Microfluidics shows a great importance in fluid control in biomedicine area. Recently, a programmable soft microfluidic system for applications of pharmacology and optogenetics is reported in Cell. Based on the theory of thermal expansion, we established an analytic model to characterize the injection process of the microfluidic systems. Finite element analyses (FEA) were employed to validate this...
To perform the drug screening, planar cultured cell models are commonly applied to test efficacy and toxicity of drugs. However, planar cultured cells are different from the human 3D organs or tissues in vivo. To simulate the human 3D organs or tissues, 3D spheroids are developed by culturing a small aggregate of cells which reside around the extracellular matrix and interact with other cells in liquid...
