Abstract
In this paper, we employed photochemical reaction for controlling the cell adhe-sion inside the microchannel. The microscale cell patterning inside the microchannel was successful, which was difficult in the glass microchip before. Using our method, cell micropatterning can be performed directly inside the microchannel without separating the substrate and cover of the microchip for surface patterning. © 2008 CBMS.
