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 …

Chronic and degenerative diseases are the main causes of death in the aging population
worldwide. These diseases are currently maintained using long term administration of …

The use of geopolymers as adsorbent materials has been increasingly investigated in the
last few years, thanks to their highly intrinsic mesoporosity and ion exchange capability. As …

Commercial pH paper is a quick and simple tool for measuring a solution's acidity/basicity,
but it only provides qualitative or semi-quantitative results, and the synthetic indicator dyes …

Inspired by traditional pH papers, two types of ratiometric fluorescent pH sensors for neutral
and alkaline pH ranges were developed in this study by using two fluorescent dyes …

Numerous methods, including pH meters and optical sensors, have been developed for the
detection of pH, which is an important indicator in various fields. However, those methods …

A novel highly selective sensitive optical sensor was prepared via the chemical
immobilization of β-2-hydroxybenzyl-5-bromo-2-hydroxyazastyrene (HBBHAS) on an epoxy …

A novel nitrogen-doped carbon dot (N-CD) was synthesized via carbonization of citric acid in
the presence of triethylenetetramine as a nitrogen source. The average size of the N-doped …

An online pH detection system is very critical in monitoring the sudden change of pH,
especially in strongly acidic and alkaline conditions. We developed a pH sensing chip which …

Chemosensors are a group of sensors—responsive sensor chemistry, sensor hardware, and
software—that report on the composition of solutions and gaseous samples. Dynamic …
