由于纳米材料具有独特的电催化性能,纳米材料越来越多地用于电化学DNA生物传感器的开发。它们为将生物识别事件与电子信号转导相结合以及设计具有新功能的新一代生物电子器件提供了良好的前景。特别是贵金属纳米粒子(Au, Pt)、碳纳米管(CNTs)、磁性纳米粒子、量子点和金属氧化物纳米粒子等纳米材料在DNA生物传感器中的应用已成为生物检测与材料科学交叉研究的新领域。在本文中,我们讨论了过去几年该领域的一些主要进展,讨论了问题和挑战,目的是激发人们对开发基于纳米材料的生物传感器的更广泛兴趣,并改善其在疾病诊断和食品安全检查中的应用。
Nanomaterials are being increasingly used for the development of electrochemical DNA biosensors, due to the unique electrocatalytic properties found in nanoscale materials. They offer excellent prospects for interfacing biological recognition events with electronic signal transduction and for designing a new generation of bioelectronic devices exhibiting novel functions. In particular, nanomaterials such as noble metal nanoparticles (Au, Pt), carbon nanotubes (CNTs), magnetic nanoparticles, quantum dots and metal oxide nanoparticles have been actively investigated for their applications in DNA biosensors, which have become a new interdisciplinary frontier between biological detection and material science. In this article, we address some of the main advances in this field over the past few years, discussing the issues and challenges with the aim of stimulating a broader interest in developing nanomaterial-based biosensors and improving their applications in disease diagnosis and food safety examination.
