Here, we report the development of an electrochemical detection method for endotoxin based on the Limulus amebocyte lysate (LAL) assay. A mixture of LAL reagent and endotoxin sample solution was incubated for 1 h. The endotoxin activated a cascade reaction of zymogens contained in the LAL to generate p-nitroaniline (pNA) which was then electrochemically detected by differential pulse voltammetry (DPV). The generated pNA gave a clear peak at –0.75 V vs. silver/silver chloride (Ag/AgCl), which…

A highly sensitive endotoxin sensor based on redox cycling in a nanocavity.

It is shown for the first time that analytes such as AMF can be detected by differences in diffusion coefficients between the analyte and coexisting molecules (such as LGR-AMF) using a device with high redox-cycling efficiency.

Electrochemical sensor with substitutional stripping voltammetry for highly sensitive endotoxin assay.

Extra-highly sensitive detection of p-aminophenol liberated by the endotoxin-induced LAL reaction was successfully realized with SSV, based on the accumulation of an amperometric signal owing to exchange of the oxidation current of pAP generated at an electrodes in a reaction cell with silver deposition on another electrode in a deposition cell.

A screen-printed endotoxin sensor based on amperometry using a novel p-aminophenol conjugated substrate for a Limulus amebocyte lysate protease reaction.

A novel amperometric measurement with a screen-printed electrode not only provides compact, low-cost, and easy-to-use sensors for on-site monitoring of endotoxin, but also shows promise for use in other in vitro protease assays for biochemical research, diagnosis, and drug development.
