The development of drug candidates or drug combinations for treating challenging diseases such as cancers and neurodegeneration diseases is becoming increasingly urgent. However, the low efficiency of conventional drug screening platforms is a bottleneck limiting the drug evaluation process. We developed series of microfluidics-based platforms for screening drugs with high-throughput and high-accuracy. We developed a micropatterned coculture-based high-content (μCHC) platform by integrating a micropatterned coculture chip with a high-content analysis (HCA) system, for studying the neuron−cancer cell interactions and drug screening (simultaneously detecting 96 kinds of post-drug-treated conditions). The results demonstrate that the μCHC system is a facile platform for screening drug candidates or drug combinations for clinical cancer therapy with high efficiency and fidelity. We also combined a concentration gradient generator (CGG) with a single-cell trapper array (SCA) on microfluidics to evaluate the concentration-dependent bioeffects of various drug candidates. The precise control of the spatiotemporal generation of drug gradients on the CGG and the single-cell-level monitoring of the cell behaviors on the SCA by a high-content system in real time, render the CGG-SCA system a highly precise platform, which can exclude the average effect of cell population and reflect the response of individual cells to the gradient concentrations accurately. The CGG-SCA system provides an automated platform for high-throughput screening of nano medicines with high precision and low sample consumption.
