Built-in electric field-boosted attomolar Pb²⁺ sensing on carboxylated black phosphorene

2026-06-02

Abstract excerpt

<title>Abstract</title> <p>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 (SPR+BP-COOH) with built-in electric field enhancement for attomolar-level and highly selective Pb²⁺ detection....
