Abstract

The invention relates to a low-dimensional nanophase material high-flexibility assembling chip and an application method, which belong to the micro-fluidic field and the nano structure material assembly field. The method realizes the electric field distributing control in a micro-fluidic body (4) according to the following two aspects to further generate micro force used for realizing assembly control: one the one hand, the on-off control of pumping signal of each pin in a pin array (11) is controlled to realize that only some microelectrode arrays (13) have electric potential so as to further change the area size of the effective bounding region of the electric field at the top of the chip; and on the other hand, a virtual aurora pattern array is projected on a photoconductive layer (32) by a micro light pattern generator (5) to further limit the electric field boundary at the bottom of the micro-fluidic body (4) in the chip.

Description

technical field [0001] The invention is a three-dimensionally controllable high-flexibility assembly chip technology of low-dimensional nanomaterials, which relates to the field of microfluidic control and the field of assembly of nanostructure materials, especially the field of active assembly of low-dimensional nanomaterials. Background technique [0002] In recent years, with the development of nanomaterial synthesis technology, metal materials, insulating materials and semiconductor materials can be assembled to form new nanostructure materials, which are used in MEMS devices and biomedical devices. Due to the differences in chemical stability and thermal stability of various nanostructured materials, there are great challenges to achieve high-level assembly of heterogeneous nanostructured materials. The currently used assembly method consists of two steps: firstly, various nanostructure materials are synthesized separately; then, a certain micro-manipulation method is u...
