Watching plants switch on genes using a fluorescent protein

Biologists often use green fluorescent protein (GFP) to see what happens inside cells. GFP, which scientists first isolated in jellyfish, is a protein that changes light from one color into another. Attaching it to other ...

Nanoengineers boost signals from fluorescent sensors

Fluorescent sensors, which can be used to label and image a wide variety of molecules, offer a unique glimpse inside living cells. However, they typically can only be used in cells grown in a lab dish or in tissues close ...

Inexpensive paper sensor accurately IDs pathogenic bacteria

Bacterial infections are the leading cause of disease and death worldwide; an ongoing public health problem exacerbated by slow or inaccurate diagnostics. Now NIBIB-funded scientists have engineered an inexpensive, paper-based ...

Edible, fluorescent silk tags can suss out fake medications

Recent developments such as the explosion of online pharmacies and supply chain issues have made it easier for counterfeiters to profit from fake or adulterated medications. Now, researchers reporting in ACS Central Science ...
