Built-in electric field-boosted attomolar Pb²⁺ sensing on carboxylated black phosphorene
Lead ion (Pb²⁺) contamination poses a severe and persistent threat to environmental safety and human health, demanding ultrasensitive and selective detection strategies. Herein, we fabricate a carboxyl-functionalized black phosphorene-modified surface plasmon resonance sensor (Au+BP-COOH) with built-in electric field...
