Researchers have developed a miniature optical fiber biosensor capable of detecting key biomarkers of diabetic retinopathy ...

Monkeypox is a growing current health concern, with a potentially fatal variant of human mpox spreading across certain African countries, and a different non-lethal variant also now being observed ...

Porous silicon (PSi) has emerged as a highly versatile material for biosensing and optical applications, owing to its high internal surface area, tunable pore sizes and exceptional optical properties.

Biosensors are important diagnostic devices that have to be quick, cheap, and easy to use. It's also beneficial if biosensors are compact and autonomous so they can be used by anyone from doctors down ...

In a recent article published in the February issue of the journal Sensors, researchers at Texas A&M University have reported a technology that might help people with gout disease monitor their ...

Optical fiber biosensors (OFBs) achieve ultra-low detection limits for biomarkers and toxins, yet face challenges in reproducibility and scalable manufacturing.

Scientists at Cornell University, NY, have developed a synthetic biosensor that mimics properties found in cell membranes and provides an electronic readout of activity. They say it “could lead to a ...

An optical sensor for RNA samples Jing Wang and his team have developed an alternative test method in the form of an optical biosensor. The sensor combines two different effects to detect the virus ...
