Abstract

A digital microfluidic chip fault repair method based on the combination of improved Dijkstra algorithm and IPSO relates to the field of digital microfluidic chip fault repair, aiming at solving the problems of time consuming and low efficiency of the existing digital microfluidic chip fault repair methods. The method comprises the following steps: first, calculating the shortest path between twodroplets to be mixed based on the improved Dijkstra algorithm; the improved Dijkstra algorithm introduces a cost function into the existing Dijkstra algorithm. The cost function guides the existing Dijkstra algorithm to search in the direction of the shortest distance to the start point, the shortest distance to the end point and the longest distance to the fault point. Step 2, calculating a moving path based on IPSO, so as to realize the shortest moving distance of droplets and complete fault repair under the condition of ensuring the completion of mixing. The invention is suitable for repairing the faults of the digital microfluidic chip.

Description

technical field [0001] The invention relates to the field of digital microfluidic chip fault repair. Background technique [0002] With the development of science and technology, the field of automatic testing has expanded from the testing of analog circuits or digital circuits to the testing of MEMS (Micro-Electromechanical Systems). Microfluidic chip, also known as Lab-on-a-chip, can complete various functions of biological laboratory and routine chemical testing on a chip of a few square centimeters. It has the characteristics of miniaturization, high sensitivity, low cost, and integration. The first generation of microfluidic biochips has permanently etched microvalves, micropumps, and microchannels, and the specific operations are based on continuous fluid flow. The development of microfluidic technology and manufacturing process has promoted the generation of digital microfluidic chips, which manipulate discrete droplets on two-dimensional microfluidic arrays and hav...
