Dynamic layer-by-layer films on nanofiber membrane: a platform for ultra-sensitive bacterial concentration detection

Abstract

Herein, a new platform was established for ultra-sensitive bacterial concentration detection. The sensing system had a linear relationship with the logarithm of bacterial concentration from 1 × 10¹ to 1 × 10⁵ CFU mL⁻¹ within 5 min. Moreover, the platform showed excellent consistency compared with the traditional standard method against practical samples.
