Gold nanoparticles and catalytic DNA produce colormetric lead sensor

Abstract:
Detecting the presence of hazardous lead paint could become as simple as pressing a piece of paper against a wall and noting a color change. The colorimetric sensor is based upon DNA-gold nanoparticle chemistry, and could be used for sensing a variety of environmental contaminants.
