A quick way to weigh molecules

A mystery substance is analysed and found to contain, let’s say, five compounds. How is that analysis actually done? How do scientists know what substances they’re working with? There’s no magic box that identifies all chemicals: it takes a lot of time, and complicated machinery. But researchers from Griffith University have figured out one way … Continue reading A quick way to weigh molecules

Using a phone to identify molecules

With a few additions, commercial smartphones can be used as microscopes and medical monitors. But the humble phone may have more applications in scientific analysis. A group of US researchers has contributed compelling research to the growing potential for phones to carry out spectroscopy, which could allow them to identify individual chemicals in drugs, contaminants … Continue reading Using a phone to identify molecules
