Embodiment Construction
[0016] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.
[0017] Such as figure 1 As shown, the liquid metal switch system based on the biospecific recognition combination of the present invention mainly includes the front storage capsule 1, the biospecific recognition molecule 2, the liquid metal micro-droplet 3, the biospecific recognition molecule receptor 4 and the back-end response Device 5 etc. The front-end storage capsule 1 is connected to the front-end control circuit, and can be selected according to the actual situation. Generally, soft materials with good biocompatibility such as polyethylene are used, which are capsule-shaped and have small holes; biospecific recognition molecules 2 are attached to the front-end storage On the thin film on the small hole surface of the capsule 1, protein antigens are generally selected; the liquid metal micro-droplet 3 is formed by the liquid metal extrud...

The invention discloses a liquid metal switching system based on combination of biological specific recognition. The liquid metal switching system comprises front-end storage bags, biological specificrecognition molecules, liquid metal micro-droplets, biological specific recognition molecule receptors and a back-end responder, wherein the front-end storage bags are connected with a front-end control circuit, liquid metal is stored in the front-end storage bags, small holes allowing the liquid metal to squeeze out are formed in the surface of the front-end storage bags, the surfaces of the small holes are covered with a thin film attached with the biological specific recognition molecules, the liquid metal squeezed out from the small holes forms the liquid metal micro-droplets covered withthe biological specific recognition molecules on the surfaces, the back-end responder is of a plate structure, through holes are distributed in the plate, the front parts of the holes are covered with the thin film modified by the biological specific recognition molecules, and the rear parts of the holes are connected with a circuit requiring switching on-off control. The liquid metal switching system can realize the switching on-off of the circuit in a liquid environment, greatly reduces the size of the system while maintaining diversity of the circuit, and can be precisely regulated and controlled.
Description
technical field [0001] The invention belongs to the technical field of liquid metal, relates to a liquid metal switch, in particular to a liquid metal switch system based on biological specific identification and combination. Background technique [0002] The switch is an important part of the circuit, and different functions of the circuit are realized by controlling the on-off of the circuit. Common switches can be divided into travel switches and photoelectric switches according to the principle. The principle of travel switch is mechanical contact, while the principle of photoelectric switch is the induction of light sensor. [0003] Implantable medical devices are one of the important directions of biomedical development in the future. They need to meet the requirements of small size, good biocompatibility and ability to work well in liquid environments. Most traditional switches do not have the ability to work normally under these conditions. condition. Therefore, h...
