Green dodecylamine-capped hafnium oxide nanosystem: evaluating the toxicity profile and electrochemical hydrogen sulfide sensing efficiency

Abstract

This research, for the first time, reports the fabrication of dodecylamine capped hafnium oxide nanomaterial (DDA@HfO2 NM) onto gold (Au) electrodes for highly selective and sensitive detection of sulfide (HS-)...

Unique three-dimensional ordered macroporous dealloyed gold–silver electrochemical sensing platforms for ultrasensitive mercury(ii) monitoring

“…As alternatives to spectroscopic techniques, electrochemical methods have been recognized as one of the most powerful tools for the determination of Hg 2+ due to their high sensitivity, short analysis duration, portability, low cost, and easy maintenance. [10][11][12] The discovery of nanomaterials has opened up numerous possibilities for electrochemical sensors because the selection of biomolecule immobilization matrixes and transducers is a critical step in constructing the appropriate biosensing device. [13][14][15] Researchers in this field are always motivated to discover novel nanomaterials that could enhance the functionality of electrochemical sensors.…”
