This is the first comprehensive review on methods and materials for use in optical sensing of
pH values and on applications of such sensors. The Review starts with an introduction that …

Fluorescence imaging techniques involving chemical sensors are essential tools in many
fields of science and technology because they enable the visualization of parameters which …

There has been a consistent increase in output related to the development and application
of optical chemical sensors since∼ 1980. The rise of activity was linked to the major …

Chemical analysis based on colour changes recorded with imaging devices is gaining
increasing interest. This is due to its several significant advantages, such as simplicity of …

There is a significant demand for devices that can rapidly detect chemical–biological–
explosive (CBE) threats on-site and allow for immediate responders to mitigate spread, risk …

An inexpensive hand-held device for analysis of colorimetric sensor arrays (CSAs) has been
developed. The device makes use of a contact image sensor (CIS), technology commonly …

We present a strategy that leads to the formation of high-performance hybrid pigments made
from natural anthraquinone chromophores (alizarin, purpurin) and mineral supports …

The simultaneous optical readout of a potentiometric sensor array of ion-selective electrodes
(ISEs) based on PVC membranes is described here for the first time. The optical array …

This article demonstrates an example of a wearable chemical sensor based on a fingernail
platform. Fingernails represent an attractive wearable platform, merging beauty products …
