Fluorescence detection 400-480nm using microfluidic system integrated GaP photodiodes

Abstract

Ciprofloxacin is a commonly used antibiotic and the active ingredient in a veterinary antibiotic. Detecting its presence allows us to understand its absorption process in blood as well as tissue. A portable microfluidic system has been fabricated. It operates at low bias voltage and shows a linear relationship between concentration levels and system response. Detection of concentrations down to 1ppb of ciprofloxacin in microliters of solution was achieved. Copyright © 2011 Dion McIntosh et al.
