[0023] [Example 1]

[0024] Please refer to Figures 1 to 8, which illustrate Embodiment 1 of the present invention. As shown in Figures 1 to 4, this embodiment discloses a non-contact particulate processing device 100, which includes a particulate container 1, an AC power device 2 electrically coupled to the particulate container 1, and a light driving device 3 facing the particulate container 1. However, the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the particulate container 1 can be used independently (e.g., for sale) or in conjunction with other devices, depending on actual needs.

[0025] In this embodiment, the particle containing device 1 is a rectangular structure at the chip-scale, and it is used to contain a liquid sample S containing a plurality of particles P, but the invention is not limited thereto. For example, the number of particles P contained in the liquid sample S can also be adjusted according to actual needs (e.g., at least one).

[0026] Furthermore, in this embodiment, the microparticle P is described as a biological microparticle; more specifically, the liquid sample S can be a bodily fluid sample from an animal (e.g., blood, lymph, saliva, or urine), and the microparticle P can be a specific type of cell or cell cluster, such as circulating tumor cells (CTCs), fetal nucleated red blood cells (FNRBCs), or bacteria, but the invention is not limited to the above. For example, in other embodiments not illustrated in this invention, the liquid sample S can also be a liquid sample from a plant. In addition, the microparticle P can also be plastic microparticles, used to adsorb viruses, bacteria, or exosomes, depending on actual needs.

[0027] The particle containing device 1 includes a photosensitive structure 11, a mating structure 12 spaced apart from the photosensitive structure 11, and an adhesive layer 13 joining the periphery of the photosensitive structure 11 and the periphery of the mating structure 12. At least one of the photosensitive structure 11 and the mating structure 12 is transparent, and in this embodiment, the photosensitive structure 11 and the mating structure 12 are two plate-like structures arranged parallel to each other with a distance between them greater than the size of any one of the particles P; however, the invention is not limited to the above description.

[0028] More specifically, the photosensitive structure 11 includes a first substrate 111, a first electrode layer 112 formed on the first substrate 111, a photoelectric layer 113 formed on the first substrate 111, and an insulator 114 formed on the photoelectric layer 113. In this embodiment, the first electrode layer 112 is formed on the bottom side of the first substrate 111, the photoelectric layer 113 is formed on the top side of the first substrate 111, and the photoelectric layer 113 has a plurality of transistors 1131 arranged in a matrix; wherein, the photoelectric layer 113 may adopt an NPN transistor architecture, a PNP transistor architecture, an NP diode architecture, or a PN diode architecture according to actual needs, but the present invention is not limited thereto.

[0029] The mating structure 12 includes a second substrate 121 and a second electrode layer 122 formed on the second substrate 121, and the second electrode layer 122 faces the photosensitive structure 11 (e.g., the photoelectric layer 113 and the insulator 114). In this embodiment, the AC device 2 is electrically coupled to the first electrode layer 112 of the photosensitive structure 11 and the second electrode layer 122 of the mating structure 12, so that the photosensitive structure 11 can be irradiated by the light emitted by the light driving device 3 to form a dielectric pattern F, thereby moving any one of the particles P within the liquid sample S through the dielectric pattern F (e.g., Figures 5 and 6).

[0030] For example, the light driving device 3 may include a camera 31 and a light source 32 associated with the camera 31. The light driving device 3 can emit light through the light source 32 to illuminate the photosensitive structure 11, so that the photosensitive structure 11 (or the photoelectric layer 113) forms the dielectric electrophoretic pattern F.

[0031] The insulator 114 includes a charge orbital T protruding from the photoelectric layer 113, and the photoelectric layer 113 is operable to generate multiple charges concentrated on the charge orbital T, such that the charge density of the charge orbital T is greater than the charge density of the outer surface of the photoelectric layer 113, so that the charge orbital T can position at least one particle P thereon by electrostatic adsorption, and the at least one particle P is defined as a target particle P1.

[0032] The photoelectric layer 113 can be used to generate multiple charges concentrated in the charge orbital T by receiving external ambient light; or, the photoelectric layer 113 can also generate multiple charges concentrated in the charge orbital T by emitting light from the light driving device 3. The present invention does not limit this.

[0033] As described above, when the target particle P1 is electrostatically adsorbed and positioned on the charge track T, the photo-driving device 3 can move the target particle P1 along the charge track T by moving the dielectrophoretic pattern F (as shown in Figures 5 and 6).

[0034] Accordingly, in this embodiment, the non-contact particle processing device 100 can form the insulator 114 on the photoelectric layer 113, so that the charge orbitals T of the insulator 114 can move and position the target particle P1 by electrostatic adsorption in conjunction with the operation of the photoelectric layer 113, thereby accurately positioning the target particle P1.

[0035] Furthermore, the charge track T can be used in conjunction with the light-driven device 3 so that the target particle P1 can be propelled by the dielectrophoretic pattern F and move rapidly along the charge track T. That is, the target particle P1 can be propelled by the dielectrophoretic pattern F (e.g., Figure 6) or moved along the charge track T after being touched (or lightly bumped) (e.g., Figure 5), thereby effectively reducing the potential damage to the target particle P1 caused by light exposure.

[0036] It should be noted that the structure of the insulator 114 can be adjusted and varied according to actual needs, provided that the charged orbital T can adsorb the target particle P1 or further provide the target particle P1 to move thereon. However, in order to enable the target particle P1 to move more smoothly and quickly on the charged orbital T, the insulator 114 preferably includes at least some of the following technical features, but the present invention is not limited thereto.

[0037] In this embodiment, as shown in Figures 2, 7, and 8, the insulator 114 includes a base layer 1141 and an orbital layer 1142. The base layer 1141 is embedded within the photoelectric layer 113, and the orbital layer 1142 is connected to the base layer 1141 and at least partially protrudes from the photoelectric layer 113. The top edge of the orbital layer 1142 forms the charge orbital T. It should be noted that the structure of the insulator 114 will be described from different angles (e.g., cross-sectional or top view) in the following description, and the insulator 114 can be designed using a structure described from a specific angle according to actual needs.

[0038] Furthermore, the insulator 114, as shown in the cross-sectional view in FIG2, comprises multiple blocks with substantially the same structure. For ease of understanding, the following description uses only one block of the insulator 114 in FIG2 (e.g., FIG7), but the invention is not limited thereto. For example, in other embodiments of the invention not shown, the multiple blocks of the insulator 114 in the cross-sectional view may have different structures.

[0039] In Figures 7 and 8 of this embodiment, the orbital layer 1142 includes two arms 1143 extending from the base layer 1141, and a gap G is formed between the inner surfaces 1143b of the two arms 1143. The free end faces 1143a of the two arms 1143 are located outside the photoelectric layer 113 and are in contact with each other, such that the gap G is jointly surrounded by the inner surfaces 1143b of the two arms 1143 and the base layer 1141, and the free end faces 1143a of the two arms 1143 form at least a portion of the charge-type orbital T.

[0040] Furthermore, each of the supporting arms 1143 includes an inner corner 1143c and an outer corner 1143d located on opposite sides of the free end face 1143a, and the height of the two inner corners 1143c is different from (e.g., lower than) the height of the two outer corners 1143d. In this embodiment, the two supporting arms 1143 are in contact with each other at their two inner corners 1143c, so that the charge track T formed by the two free end faces 1143a is approximately V-shaped and facilitates the movement of the target particle P1 on it. Moreover, since each supporting arm 1143 has the inner corner 1143c and the outer corner 1143d, it is beneficial for multiple charges to concentrate at the inner corner 1143c and the outer corner 1143d.

[0041] From another perspective, as shown in the top views of Figures 4 to 6, the charge-type track T includes multiple transverse track slots T1 and multiple longitudinal track slots T2. Each transverse track slot T1 is parallel to a first direction D1, and each longitudinal track slot T2 is parallel to a second direction D2, intersecting with the multiple transverse track slots T1. In this embodiment, the first direction D1 and the second direction D2 are perpendicular to each other, but this is not a limitation.

[0042] Furthermore, each of the multiple transverse track slots T1 and the multiple longitudinal track slots T2 at their intersections is defined as a charge concentration region T3. When the photoelectric layer 113 operates to generate multiple charge concentrations in the charge-type track T, the charge concentration region T3 has the highest charge density within the photosensitive structure 11, thereby facilitating the electrostatic adsorption of the target particle P1 to any one of the charge concentration regions T3.

[0043] Looking at Figures 4 and 7 together, in this embodiment, any one of the plurality of transverse track grooves T1 and the plurality of longitudinal track grooves T2 is equivalent to being formed by two support arms 1143. That is, any one of the plurality of transverse track grooves T1 and the plurality of longitudinal track grooves T2 has two adjacent inner corners 1143c and two outer corners 1143d located outside the two inner corners 1143c. Furthermore, in any one of the plurality of transverse track grooves T1 and the plurality of longitudinal track grooves T2, the height position of the two inner corners 1143c is different from (e.g., lower than) the height position of the two outer corners 1143d.

[0044] It should be further noted that, as shown in Figure 4, the transverse track groove T1 is a continuous groove along the first direction D1 without segmentation, and the longitudinal track groove T2 can also be a continuous groove along the second direction D2 without segmentation, but the present invention is not limited thereto.

[0045] Furthermore, in this embodiment, the particle containing device 1 is described with the photosensitive structure 11 in conjunction with the mating structure 12 and the bonding layer 13, but the present invention is not limited thereto. For example, in other embodiments of the present invention not shown, the photosensitive structure 11 may be used independently (e.g., for sale) or in conjunction with other structures, depending on actual needs.

[0046] [Example 2]

[0047] Please refer to Figure 9, which illustrates Embodiment 2 of the present invention. Since this embodiment is similar to Embodiment 1 described above, the similarities between the two embodiments will not be repeated. The differences between this embodiment and Embodiment 1 are roughly explained as follows:

[0048] In this embodiment, the free end faces 1143a of the two arms 1143 are located outside the photoelectric layer 113 and are far apart from each other, so that the gap G is connected to the outside, and the inner side faces 1143b of the two arms 1143 form at least a portion of the charge track T.

[0049] More specifically, the height of the inner corners 1143c of the two arms 1143 is higher than the height of the outer corners 1143d of the two arms 1143. In this embodiment, the two arms 1143 are positioned such that their inner corners 1143c are far apart from each other, so that the charge track T formed by the inner surfaces 1143b of the two arms is approximately V-shaped and facilitates the movement of the target particle P1 on it. That is, the target particle P1 can be partially located within the gap G.

[0050] [Example 3]

[0051] Please refer to Figure 10, which illustrates Embodiment 3 of the present invention. Since this embodiment is similar to Embodiments 1 and 2 described above, the similarities between the two embodiments will not be repeated. The differences between this embodiment and Embodiments 1 and 2 are roughly explained as follows:

[0052] In this embodiment, each of the transverse track grooves T1 is composed of multiple segments along the first direction D1, and each of the longitudinal track grooves T2 is composed of multiple segments along the second direction D2. The segmented structure of the transverse track grooves T1 and the longitudinal track grooves T2 can be adjusted and varied according to actual needs. The following description only illustrates one preferred embodiment and is not limited thereto.

[0053] More specifically, the orbital layer 1142 includes a plurality of annular segments 1144 surrounding a plurality of transistors 1131, and the plurality of annular segments 1144 are arranged adjacent to each other in a matrix, and the top edges of the plurality of annular segments 1144 together constitute the charge-type orbits T. That is, the top edges of the plurality of annular segments 1144 together constitute a plurality of transverse orbital slots T1 and a plurality of longitudinal orbital slots T2.

[0054] Furthermore, the outer contour of each of the annular segments 1144 is square, and the charge concentration region T3 is formed at the center of any four adjacent annular segments 1144 arranged in a square. From another perspective, any two adjacent arms 1143 belong to two separate annular segments 1144.

[0055] [Technical Effects of the Embodiments of the Invention]

[0056] In summary, the particle containing device and non-contact particle processing equipment and their photosensitive structure disclosed in the embodiments of the present invention can move and position the target particles by forming the insulator on the photoelectric layer, so that the charge track of the insulator can be matched with the operation of the photoelectric layer, thereby accurately positioning the target particles by electrostatic adsorption.

[0057] Furthermore, the charge-type track can be used in conjunction with the light-driven device to enable the target particle to be propelled by the dielectrophoretic pattern and move rapidly along the charge-type track. In other words, the target particle can be propelled by the dielectrophoretic pattern or moved along the charge-type track after being touched (or lightly bumped), thereby effectively reducing the potential damage to the target particle caused by light saturation.
