Mold or injection molding process for single cell capture chip

Abstract

The invention relates to the technical field of micro-fluidic chips, and discloses a mold for a single cell capture chip. The mold comprises a frame, the frame is internally provided with uniformly distributed injection molding grooves, diversion pipes are installed between the injection molding grooves in a communication manner, the left and right ends of the interior of the frame are fixedly provided with fixing plates, and driving rods are fixedly mounted at the upper ends and the lower ends in the fixing plates. According to the mold or injection molding process for the single cell capture chip, an electric control rod is driven by the driving rods to move, the electric control rod performs magnetic induction line cutting motion in a magnetic field formed by an electromagnetic plate so as to generate induction current, and the induction current enters first arc-shaped teeth and second arc-shaped teeth through wires, and then in the relative movement process of the first arc-shaped teeth and the second arc-shaped teeth, internal resistance change can be caused, so that the resistance change and the voltage change can be known according to the Ohm law, and the injection molding state in the frame can be known in time through a sensor.

Description

technical field [0001] The invention relates to the technical field of microfluidic chips, in particular to a mold or injection molding process for a single-cell capture chip. Background technique [0002] Microfluidic chip, also known as micro-total analysis system or lab-on-a-chip, refers to the integration or It is basically integrated into a chip of a few square centimeters or even smaller, and then forms a network through microchannels, and the controllable fluid runs through the entire system. [0003] In microfluidic chips, it is generally necessary to make and package chip molds. When injecting fluid packaging materials into the mold, the continuous flow of liquid will enter the packaging groove, but the adhesive strength of these fluid materials is very high. It cannot fully flow into all corners of the packaging groove, resulting in poor packaging injection molding effect, and it is impossible to know the injection molding situation in real time during the chip in...
