Abstract
Heavy metal ion pollution is a serious environment problem that has attracted more and more attentions in recent years. Mercury ion (Hg 2+ ) and lead ion (Pb 2+ ) are two of the most toxic metallic pollutants even at an extremely low concentration. Copper ion (Cu 2+ ), an essential micronutrient element for human life, can cause adverse health effects when present in high concentrations. Considerable efforts have been devoted to the detection of heavy metal ions due to their high toxicity towards the ecosystem and human health. Unlike the traditional detection technologies, we have developed some simple and sensitive biosensors without the requirement of sophisticated instrumentation and skilled personnel. With the combination of DNAzyme, DNA machine and lateral flow biosensor, the visual instrument-free method offers a point-of-use solution for heavy metal ion analysis and provides a basis for the future work aiming at the development of household devices for sensitive detection of various analytes.
