An ultrasensitive electrochemical sensor for phospholipase C via signal amplification based on breathing ATRP and its application

Abstract

An ultrasensitive electrochemical sensor for phospholipase C was developed via signal amplification based on breathing ATRP.

In situ growth of a cobalt porphyrin-based covalent organic framework on multi-walled carbon nanotubes for ultrasensitive real-time monitoring of living cell-released nitric oxide

“…The sensitivity was determined from the slope = 8.9 μA μM −1 cm −2 , and the sensor was found to have a low detection limit for NO (16 nM). 46,47 Table S1† lists the performance of the proposed electrochemical sensor compared to other NO sensors, showing that the analytical parameters obtained using MWCNTs@COF-366-Co were better than those obtained using several recently reported sensors. Hence, MWCNTs@COF-366-Co is a promising NO electrochemical sensor with fast response, wide linear range, high sensitivity, and low detection limit.…”
