Abstract

Modern medicine has increased the human lifespan. However, with an increase in average lifespan risk of amyloidosis increases. Amyloidosis is a condition characterized by protein misfolding and aggregation. Early detection of amyloidosis is crucial, yet conventional diagnostic methods are costly and lack precision, necessitating innovative tools. This review explores recent advancements in diverse amyloid detection methodologies, highlighting the need for interdisciplinary research to develop a miniaturized electrochemical biosensor leveraging nanotechnology. However, the diagnostics industry faces obstacles such as skilled labor shortages, standardized selection processes, and concurrent multi-analyte identification challenges. Research efforts are focused on integrating electrochemical techniques into clinical applications and diagnostics, with the successful transition of miniaturized technologies from development to testing posing a significant hurdle. Label-free transduction techniques like voltammetry and electrochemical impedance spectroscopy (EIS) have gained traction due to their rapid, cost-effective, and user-friendly nature.

用于检测和表征淀粉样蛋白的生物传感器的最新进展：综述。

现代医学延长了人类的寿命。然而，随着平均寿命的延长，患淀粉样变性病的风险也随之增加。淀粉样变性是一种以蛋白质错误折叠和聚集为特征的疾病。早期检测淀粉样变性至关重要，但传统诊断方法成本高昂且缺乏精确性，因此需要创新工具。本综述探讨了各种淀粉样蛋白检测方法的最新进展，强调了利用纳米技术开发微型电化学生物传感器的跨学科研究的必要性。然而，诊断行业面临着各种障碍，如熟练劳动力短缺、标准化选择流程以及同时进行多种分析鉴定的挑战。研究工作的重点是将电化学技术整合到临床应用和诊断中，而微型化技术从开发到测试的成功过渡则是一个重大障碍。伏安法和电化学阻抗光谱法（EIS）等无标记传导技术因其快速、成本效益高和用户友好的特性而备受青睐。
