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.

Engineers have harnessed quantum physics to detect the presence of biomolecules without the need for an external light source, overcoming a significant obstacle to the use of optical biosensors in ...

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 ...

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 ...

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 ...

A new variant of human mpox has claimed the lives of approximately 5% of people with reported infections in the Democratic Republic of the Congo since 2023, many of them children. Since then, it has ...

Without the prospect of herd immunity on the immediate horizon, speedy detection for COVID-19 remains imperative for helping to curb the pandemic. Point-of-care testing that can provide immediate ...

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 ...

A telecommunications engineer of the NUP/UPNA-Public University of Navarre, has designed in his Ph.D. thesis optical resonance-based biosensors for use in medical applications like, for example, the ...

Scientists at the National Research Nuclear University MEPhI (MEPhI) have studied the optical properties of detonation nanodiamonds when interacting with various biomacromolecules (biopolymer ...

Cancer is often most dangerous when it hides in the early stages. Detecting it before symptoms appear is one of the biggest challenges in modern medicine. Now, researchers from the Korea Institute of ...
