摘要

本研究开发了一种基于sepiolite@Pt电催化剂的新型非酶安培传感器,用于测定乳酸盐。小尺寸铂纳米颗粒(NPs)的均匀分散优化了电子传递动力学,从而降低了改性碳浆电极(CPE)的乳酸盐检测能力。该创新型传感平台对 10 至 1100 µM 的乳酸盐浓度具有线性响应。信噪比为 3σ,检测限为 2 µM。此外,对人体液中乳酸盐的精确分析表明,所提出的方法是一种高度特异性的乳酸盐监测工具。值得注意的是,该传感器的功能已扩展到测量体育锻炼时唾液样本中的乳酸盐浓度。所提出的方法提供了一种经济高效的乳酸盐监测手段,可实现快速分析和简化临床检测程序。

A Novel Clay Based Electrocatalyst for Lactate Detection in Saliva and Blood Samples during Exercise in Athletes

A Novel Clay Based Electrocatalyst for Lactate Detection in Saliva and Blood Samples during Exercise in Athletes

In this research, a new non-enzymatic amperometric sensor has been developed for the determination of lactate based on a sepiolite@Pt electrocatalyst. The uniform dispersion of small-sized platinum nanoparticles (NPs) leads to optimized electron transfer kinetics, thereby low lactate detection ability of the modified carbon paste electrode (CPE). The innovative sensing platform demonstrates a linear response to lactate concentrations ranging from 10 to 1100 µM. By using a signal-to-noise ratio of 3σ, a detection limit of 2 µM was established. Moreover, the precise analysis of lactate in human fluids suggests that the proposed method is a highly specific tool for lactate monitoring. Notably, the sensor’s capabilities were extended to include the measurement of lactate concentrations in saliva samples obtained during sport practice. The proposed method offers a cost-effective and efficient means of lactate monitoring, enabling rapid analysis times and streamlined clinical testing procedures.
