What is Fluorescence Correlation Spectroscopy (FCS)? Fluorescence correlation spectroscopy (FCS) is a powerful analytical technique that enables the study of dynamic processes and interactions at the ...

The spectrum of a substance — how it interacts with light — provides fundamental insight into its composition. A large number of molecules is typically required to obtain a detectable light-absorption ...

In a recent article published in Nature Nanotechnology, researchers introduced an approach in single-molecule spectroscopy, significantly improving the ability to probe quantum transitions in ...

Atomic Force Microscopy-based SMFS is widely used due to its high force sensitivity and spatial resolution. In this technique, a biomolecule is attached between a surface and an AFM cantilever. As the ...

Infrared vibrational spectrum of a single protein is observed using advanced measurement techniques based on near-field optical microscopy. This method utilizes light confined at the nanometer scale, ...
