Abstract

Amperometric biosensors of different designs are often reported as having a logarithmic dependency on the target concentration. This paper provides a physicochemical basis for this behaviour if the adsorption of the analyte follows the Temkin Adsorption Isotherm over the range of concentrations of interest either by directly controlling the amount adsorbed or indirectly via the effect on the electrochemical rate constant.

安培生物传感器：为什么响应可能显示对分析物浓度的对数依赖？

不同设计的安培生物传感器通常被报道为对目标浓度具有对数依赖性。本文为这种行为提供了物理化学基础，如果被分析物的吸附在感兴趣的浓度范围内遵循Temkin吸附等温线，要么直接控制吸附量，要么间接通过对电化学速率常数的影响。

期刊介绍： Electrochemistry Communications is an open access journal providing fast dissemination of short communications, full communications and mini reviews covering the whole field of electrochemistry which merit urgent publication. Short communications are limited to a maximum of 20,000 characters (including spaces) while full communications and mini reviews are limited to 25,000 characters (including spaces). Supplementary information is permitted for full communications and mini reviews but not for short communications. We aim to be the fastest journal in electrochemistry for these types of papers.
