Example Embodiment
[0051] The specific embodiment of the present invention is described below:
Example Embodiment
[0052] Specific Embodiment 1: This embodiment provides a digital microfluidic chip online testing method based on the combination of tabu search and artificial potential field method. The method of the present invention is used to generate the moving path of the test droplet on the digital microfluidic chip. The movement path is represented by a sequence of nodes; the nodes are used to represent the electrodes on the digital microfluidic chip;
[0053] The method of the present invention comprises the following steps;
[0054] Step 1: Establish a mathematical model for online testing of digital microfluidic chips, and construct a taboo table.
[0055] Among them, the test task can be described as:
[0056] Starting from the starting point, the test droplet visits each node in the graph in turn according to a certain selection mechanism. In the process of searching the path, it is necessary to avoid the merging and interference areas of the test droplet at the corresponding ti...
Example Embodiment
[0075] Specific implementation mode two: the difference between this implementation mode and specific implementation mode one is:
[0076] In step 1, the mathematical model for establishing the online test of the digital microfluidic chip is specifically as follows:
[0077] Establish a model in which the test droplet traverses all vertices and their neighborhoods, the expression is:
[0078]
[0079] Wherein, t is the moment, j is the vertex where the test droplet is located, i is the vertex where the test droplet is located, and N(i) is the neighborhood of vertex i; is the value used to record whether the test droplet moves from position i to position j at time t, if so, then The value of is 1, if not, then value of 0.
[0080] The moving path of the test droplet needs to meet the following fluid constraints:
[0081]
[0082]
[0083] Among them, MR(j, t) indicates the area where the droplets that can fuse with the droplet at position j exist at the same tim...
