Abstract

Biomedical diagnostic devices always have crucial aspects on development of biomedical technology. Blood sampling process through microchannels is required in biomedical diagnostic devices. In this paper, we have investigated advancing meniscus of biomedical sample in various side-wall shaped microchannels. Advancing meniscus of liquid mainly depends on side-wall shape of microchannel, even though dynamic contact angle is sustained as same value regardless of side-wall shape.
