Duetta is a highly sensitive spectrofluorometer that can be used to measure transferrin at very low concentrations. By ...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is initiated by an interaction between the human angiotensin-converting enzyme type 2 (ACE2) receptor and the SARS-CoV-2 spike (S ...

Many fluorescent proteins are currently available for biological spectroscopy and imaging measurements, allowing a wide range of biochemical and biophysical processes and interactions to be studied at ...

(Nanowerk News) Proteins are naturally fluorescent in the ultraviolet, offering an appealing approach to probe proteins in their native state without introducing any external fluorescent label. The UV ...

The application of the simultaneous absorbance-transmission and fluorescence excitation-emission matrix method (A-TEEM) can be used for absorbance measurements or fluorescence EEM for multicomponent ...

Dynamics Author: Howard Goldner During the past few decades, fluorescence spectroscopy has developed into an integral technique in many scientific disciplines. In the life sciences, it is implemented ...

Rice University scientists have effectively quenched a debate over the mechanism behind a fluorescent biosensor that monitors neurons by sensing changes in voltage. The work led by Rice theoretical ...

Fluorescence correlation spectroscopy (FCS) measurements have been carried out on the intestinal fatty acid binding protein (IFABP) to study microsecond dynamics of the protein in its native state as ...

Biomedical and genetic engineers at Duke University and the Albert Einstein College of Medicine have designed a small fluorescent protein that emits and absorbs light that penetrates deep into ...

The integration of O-PTIR and laser scanning technologies is advancing microplastics analysis, offering superior chemical ...
