Reusable microfluidic chip for pesticides detection

HKUST
Overview

HKUST developed a nanoporous silver (NPAg) sheet integrated microfluidic chip for sensitive label-free pesticide fast detection. The sensitive microfluidic chip has a detection limit down to a level which is lower than the maximum residue limits in many kinds of food set by the government regulators.
