What are some popular uses of UV-Vis spectrophotometry?

UV-Vis spectrophotometry has a diverse range of applications in both academia and industry. Here are some articles detailing common - and novel - applications.

1. Characterisation and effect of pharmaceuticals

In early drug discovery and development, UV-Vis is a common technique implemented to identify and produce the active pharmaceutical ingredient in medicines. It is also implemented to quantify the level of impurities present. For oral medicines, the analysis of the rate and extent of drug release or dissolution can be measured using spectrophotometry techniques.

2. Characterisation and uses of nanoparticles

Nanoparticles are utilised in a vast number of science and industrial applications, from cosmetics and paints to medicines and construction materials. In order to use these materials correctly and safely, we must determine with confidence the size and chemical make-up of these nanoparticles. This can be done with UV-Vis spectrophotometry.

3. Quality analysis of water and determination of impurities

The availability of drinkable water is of upmost importance to life on earth. Impurities such as heavy metals or some microbiological contaminants can have disastrous effects on local human and wildlife populations. It is therefore useful to be able to asses the quality of water to determine how to purify it, and then to reliably confirm the level of purity. This can be done using UV-Vis methods.
