- ... Because of the severe health risks associated with lead pollution, rapid, sensitive, and portable detection of low levels of Pb²⁺ in biological and environmental samples is of great importance. In this work, a Pb²⁺-responsive hydrogel was prepared using a DNAzyme and its substrate as cross-linker for rapid, sensitive, portable, and quantitative detection of Pb²⁺. Gold nanoparticles (AuNPs) were fi ...
