摘要
We demonstrate the use of a microfluidic device that accurately monitors bacteria levels in water. Fluorescent antibody labelled E. coli K12 bacteria in aqueous samples are flowed through the device, and spikes in the emission signal correspond to the presence of bacteria. Target bacteria could also be detected while suspended in a suspension of very low antibody concentration, suggesting that washing of bacteria could be avoided to make the detection automated and more rapid. Use of a microfluidic device will eventually enable quick on-site detection of bacteria using small quantities of sample.
