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 …

Biosensors that detect and convert biological reactions to a measurable signal have gained
much attention in recent years. Between 1950 and 2017, more than 150,000 papers have …

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 …

A general quantitative pH sensor for environmental and intracellular applications was
developed by the facile hydrothermal preparation of dicyandiamide (DCD) N-doped high …

We have developed a near-IR reversible fluorescent probe containing an organoselenium
functional group that can be used for the highly sensitive and selective monitoring of …

There is an enormous demand for chemical sensors for many areas and disciplines. High
sensitivity and ease of operation are two main issues for sensor development. Fluorescence …

In the last years, itaconic acid has gained increasing interest as future bio-based platform
chemical. To replace petrol-based compounds such as methacrylic acid in industry, the …

A near-neutral pH near-infrared (NIR) fluorescent probe utilizing a fluorophore-spacer-
receptor molecular framework that can modulate the fluorescence emission intensity through …

Optical chemical sensors are capable of continuously recording a chemical species and
thus have found (and will find) numerous applications in areas such as the chemical …

This review focuses on the emerging field of miniature bioreactors (MBRs), and examines
the way in which they are used to speed up many areas of bioprocessing. MBRs aim to …
