Gold nanomaterial-based miniaturized NSET Probe for rapid and ultra-sensitive detection of toxic metals from environment

摘要

Contamination of the environment with heavy metal ions has been an important concern throughout the world for decades. Here we discuss our recent effort on the development of a miniaturized and battery operated ultra?sensitive gold nanoparticle based nanomaterial surface energy transfer (NSET) probe for screening toxic metal levels in contaminated soil, water and fish which has excellent sensitivity and selectivity. Further we describe the quenching efficiency and mechanism as a function of size and shape of gold nanoparticles
