Abstract

The increasing number of deaths from cardiovascular diseases has become a substantial concern in both developed and underdeveloped countries. Rapid and on-site monitoring of this disease is urgently important to control, prevent and make awareness of public health. Recently, a lot of focus has been placed on nanomaterials and modify these nanomaterials have been explored to detect cardiac biomarkers. By implementing biosensors that are modified with novel recognition elements and more stable nanomaterials, the use of electrochemistry for point-of-care devices is more realistic every day. This review focuses on the current state of nanomaterials conjugated biorecognition elements (enzyme integrated with nanomaterials, antibody conjugated nanomaterials and aptamer conjugated nanomaterials) for electrochemical cardiovascular disease detection. Specifically, a lot of attention has been given to the trends toward more stable biosensors that have increased the potential to be used as point-of-care devices for the detection of cardiac biomarkers due to their high stability and specificity. Moreover, the recent progress on biomolecule-free electrochemical nanosensors for cardiovascular disease detection has been considered. At last, the possibility and drawbacks of some of these techniques for point-of-care cardiac device development in the future have been discussed.

摘要

心血管疾病导致的死亡人数不断增加,这在发达国家和发展中国家都是一个重大问题。快速和现场监测这种疾病对于控制、预防和提高公众健康意识至关重要。最近,人们对纳米材料给予了大量关注,并探索了对这些纳米材料进行修饰,以检测心脏生物标志物。通过实施修饰有新型识别元件和更稳定纳米材料的生物传感器,电化学在即时检测设备中的应用变得越来越现实。本综述重点介绍了当前用于电化学心血管疾病检测的纳米材料共轭生物识别元件(酶与纳米材料结合、抗体与纳米材料结合和适体与纳米材料结合)的现状。具体来说,由于其高稳定性和特异性,更多关注的是朝着更稳定的生物传感器的发展趋势,这增加了其作为即时检测心脏生物标志物的设备的潜力。此外,还考虑了用于心血管疾病检测的无生物分子电化学纳米传感器的最新进展。最后,讨论了这些技术在未来即时检测心脏设备开发中的可能性和缺点。
