Colorimetric Nanofibers as Optical Sensors [PDF]

Advanced Functional Materials, 2017
Sensors play a major role in many applications today, ranging from biomedicine to safety equipment, where they detect and warn us about changes in the environment. Nanofibers, characterized by high porosity, flexibility, and a large specific surface area, are the ideal material for ultrasensitive, fast‐responding, and user‐friendly sensor design ...

A colorimetric sensor based on citrate-stabilized AuNPs for rapid pesticide residue detection of terbuthylazine and dimethoate

Sensors and Actuators B: Chemical, 2018
A new colorimetric sensor based on citrate-stabilized AuNPs was proposed for the rapid pesticide residue detection of both terbuthylazine (TBA) and dimethoate (DMT) with ultra-sensitivities and high selectivities.

Threshold-Responsive Colorimetric Sensing System for the Continuous Monitoring of Gases

Sensors, 2023
Colorimetric sensors are widely used because of their inherent advantages including accuracy, rapid response, ease-of-use, and low costs; however, they usually lack reusability, which precludes the continuous use of a single sensor.
