Rapid Broad-Spectrum Colorimetric Detection of Bacteria Using Polylysine-Mediated Gold Nanoparticle Aggregation.

Rapid on-site detection of bacterial contamination remains an urgent need in public health and environmental monitoring. Herein, we report a one-step, label-free colorimetric sensor for broad-spectrum bacterial detection based on a competitive electrostatic mechanism. Cationic poly-l-lysine (PLL) induces the aggregatio...
