A major step forward toward biosensor devices that can provide fast, high-contrast detection of biomarkers in almost any environment are 'binding-activated fluorescent biosensors.' Now, a research ...

Scientists at Oak Ridge National Laboratory have developed the first-ever method of detecting ribonucleic acid, or RNA, inside plant cells using a technique that results in a visible fluorescent ...

Schematic of a generic biosensor architecture. The target analyte interacts with an immobilized bioreceptor layer, and the resulting molecular recognition event is translated by a physico-chemical ...

Binding-activated biosensors exposed to an “excitation light” of a specific wavelength only emit fluorescent light of a different fluorescent wavelength when their fluorogenic fluorescent scaffolds ...
