Abstract

The invention discloses a lossless transfer device for droplets. The device comprises a power generation part and a clamping part, the power generation part comprises a movable friction material and at least two fixed friction materials, the clamping part comprises a supporting mechanism, a left dielectric wetting clamping plate and a right dielectric wetting clamping plate, the left dielectric wetting clamping plate and the right dielectric wetting clamping plate are installed on the supporting mechanism, the movable friction materials are connected with the left dielectric wetting clamping plate, and the at least two fixed friction materials are connected with the right dielectric wetting clamping plate. The invention also discloses a lossless droplet transfer method and a droplet micro-reaction method. The device is more portable; by using a crank connecting rod mechanism, the left dielectric wetting clamping plate moves in the horizontal direction, and the device can adapt to liquid drops of different sizes conveniently; the accuracy of horizontal movement of the left clamping plate is ensured; a bolt and a spring are arranged, so that the left dielectric wetting clamping platecan horizontally move leftwards or rightwards conveniently; and the movement of droplets can be controlled, and the driving and fusion of the droplets are realized.

Description

technical field [0001] The invention relates to the technical field of micro-droplet control, in particular to a non-destructive droplet transfer device and method based on a frictional nanogenerator, and a droplet micro-reaction method. Background technique [0002] With the rapid development of biochemical technology, the demand for the improvement and optimization of its research equipment is also increasing. The invention and development of micro-droplet equipment has brought new ideas to the experimental research of biology and chemistry. The key to the micro-droplet device is the driving method of the droplet. The existing driving methods include electric drive (EWOD), magnetic drive, surface acoustic wave drive, mechanical drive and so on. The dielectric wetting (EWOD) method is a commonly used droplet control method, but this method of driving droplets often requires huge external equipment and special microfluidic chips, which greatly reduces the universality of EW...
