In this paper, we present a novel microfluidic optical
sensing system by combining a low-power conductive polymer
-based microfluidic pump and a microfluidic chip integrated
with an optical sensor. A self priming microfluidic pump is
developed using a polypyrrole. A microfluidic chip- optical
detector module that contained an optical cuvette with LED
and photo-diode optical sensing module was fabricated.
Integration of the micro pump and the microfluidic chips
complete the sensing system. The pump performance and its
application in chemical analysis have been demonstrated in the
detection of Fe ions.
