CAPILLARY-ASSEMBLED MICROCHIP (CAs-CHIP) : A NEW METHOD FOR INTEGRATING MULTIPLE CHEMICAL FUNCTIONS ONTO A SINGLE MICROFLUIDIC DEVICE

摘要

A novel concept of assembling various chemical functions onto a single microfluidic device is proposed. The concept, "CAPILLARY-ASSEMBLED MICROCHIP (CAs-CHIP), involves embedding chemically functionalized square capillaries onto a lattice microchannel network fabricated on polydimethyl siloxane (PDMS) possessing same channel dimensions to outer dimensions of square capillaries (Figure 1). This approach would allow easy fabrication of chemically-functionalized microfluidic device by freely embedding functional square capillaries on PDMS microchannel network. Here we report a fabrication method of CAs-CHIP, and an application for preparing a multiple chemical sensing chip as an example.
