Abstract

We prepared multi-step "Laplace pressure valves" in a TiO 2 modified microchannel by photocatalytic analog lithography (PAL). Utilizing the Laplace pressure valves, 11-nL liquid dispensing and a reaction chamber with 3-step Laplace pressure valves were successfully prepared. By combining them, volume regulated analysis systems such as a microchip titration system can be constructed.
