Lire la suite >Micro-electromechanical systems (MEMS) tweezers developed for the trapping and characterization of bio molecules such as DNA are also capable of cell handling, which will enable further application involving single cell characterization. However, cellular adhesion to Si tweezers surfaces can inhibit the release of cells after capture and analysis. To allow for high-throughput cell handling, the surface modification process for probe sidewalls was optimized. The hydrophilicity of sample silicon wafers modified with various chemical coatings was measured to identify the optimal process. The surface modification was then applied to MEMS probes and the feasibility of cell capture/release was evaluated.Lire moins >
