英文摘要：

Much attention has been drawn to nanoparticles in electrochemical deoxyribonucleic acid （DNA） biosensors due to the advantage of enhancing the sensitivity of the biosensors. Nanoparticle tagging DNA probe,which combines of nano- technology, gene project and DNA detection, is the focus of recent research field. The principle and classification, labelled methods and principle of detection of nanoparticle tagging DNA probe are introduced. The applications of nanoparticles tagging DNA probe in electrochemical DNA biosensors arc reviewed.
