Graphene Analysis: How to Configure Your Raman Microscope

In our Year of Graphene series, we've showcased why Raman microscopy is ideal for analysing graphene and other 2D materials. But what exactly is a Raman microscope, and what factors should be considered to optimise your Raman Microscope for graphene analysis?

Map of the Month – Pharmaceutical API Detection

In this Map of the Month, a formulation containing the API cetirizine (CTZ) hydrochloride, a widely used antihistamine, was imaged using the Edinburgh Instruments RM5 Confocal Microscope.

What is Photoinduced Electron Transfer? 

In photoinduced electron transfer, an electron is transferred from a photoexcited donor molecule to an acceptor molecule. The process results in charge separation and the formation of a radical cation of the donor and a radical anion of the acceptor.

What is Dexter Energy Transfer?

Dexter energy transfer, also called electron exchange energy transfer, is a photophysical mechanism where a simultaneous exchange of electrons occurs between donor and acceptor molecules.

What is Förster Resonance Energy Transfer (FRET)?

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.

What is a Fluorescence Spectrometer?

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.

What is a Stern-Volmer Plot?

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

What is Fluorescence Quenching?

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