Abstract:
Microfluidics with the ability to control Nano-to-Pico meter volumes have caused the revolution in the systems of analytical biology and chemistry. However, the most Lab-On-Chip technologies (LOCs) depend on external control elements, so a lab is required to operate a chip. Bubble or drop logic through the bubble (drop) can control the flow internally and intrinsically digitally without utilizing of off-chip or moving components. Non-linearity is applied by using mutual drop-drop' effects on reversible linear flow in low Reynolds. for the proper exploitation of microfluidic systems, It is necessary to control droplet generation systems in one chip appropriately. The most crucial part of the microfluidic system is the droplet generation system. In this study, with bubble logic, three simple and powerful mechanisms for controlling the droplet generation line are introduced. The foundations of all the proposed mechanisms are the hydraulic resistance of the flow path and the interaction between the drops. In the present study, the numerical finite element method and COMSOL Multiphasic software are employed to illustrate the mechanisms function
