Rapid quantification of bacterial cells in potable water using a simplified microfluidic device.

A simplified microfluidic device for quantification of bacteria in potable water was fabricated and examined. Comparisons of counts of Escherichia coli by the microfluidic system and by epifluorescence microscopy closely correlated (r2=0.99). Bacteria in natural mineral water and in purified household tap water were accurately enumerated by using this system within 15 min after fluorescent staining.

Rapid and simple quantification of bacterial cells by using a microfluidic device.

This study investigated a microfluidic chip-based system (on-chip flow cytometry) for quantification of bacteria both in culture and in environmental samples. Bacterial numbers determined by this technique were similar to those obtained by direct microscopic count. The time required for this on-chip flow cytometry was only 30 min per 6 samples.
