Förster resonance energy transfer is a photophysical mechanism where energy is transferred from an excited molecule (the donor) to another molecule (the acceptor) via a dipole-dipole resonance interaction.

A fluorescence spectrometer is used to study the fluorescence properties of a sample. It excites a sample with a specific wavelength of light and measures the intensity and spectral distribution of the resulting fluorescence emission.

The Stern-Volmer plot is used to study the interaction dynamics between a fluorescent emitter and a quencher.

Fluorescence quenching is the decrease in fluorescence intensity of an emitter due to interaction with a quencher.

How exactly do you obtain a great Raman spectrum of graphene? This month's "20 Years of Graphene" instalment tells you exactly how to set up your Raman microscope to take a great Raman spectrum. 

In this celebration of graphene, our eBook delves into more than just graphene as it explores forms of carbon and 2D materials. Download the eBook and find out more about these cutting edge materials.

Chicago's iconic green river for St. Patrick's Day hides a surprising environmental twist! Originally, a harmful dye impacted aquatic life. Discover the switch to a safer alternative and delve into the fascinating science behind the vibrant green spectacle.

DNA is so small, that even with powerful microscopes it is difficult for us to see, so scientists use special fluorescent labels to make it easier to investigate. Discover the incredibly creative way one of our scientists, Alix, explains why scientists use fluorescent labels and how they work!

Graphene 20: We continue our celebration of Graphene by taking a closer look at the structure of the material. Using Raman spectroscopy, discover how you can investigate the quality of graphene, defects and even its local environment.

We spoke to CJ, Head of Marketing here at Edinburgh Instruments to find out more about her and her job role here. At Edinburgh Instruments, we are proud of all our employees for all they do behind the scenes, so we thought it was time to put them in the spotlight. This series does exactly that!
