The term “biosensor” is short for “biological sensor” and is a device made up of a transducer and a biological element that may be an enzyme, an antibody, or a nucleic acid. The biological element or ...

Part 1 of this series provided an overview on using reflectometry for a pulse plethysmograph (PPG) waveform and described the physical and physiological principles at work. Much attention has been ...

(Nanowerk Spotlight) The application of nanotechnology to biosensor design and fabrication promises to revolutionize diagnostics and therapy at the molecular and cellular level. The convergence of ...

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 ...

As the World Health Organisation (WHO) keeps monkeypox on highest alert level even months later, a new research finding has found a convenient method to detect the monkeypox virus easily. "There is an ...

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 ...

Label-free and highly sensitive optical transducers are commonly based on whispering gallery modes (WGMs) excited in microcavities, with applications ranging from clinical diagnostics 1,2 and ...

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 ...

WASHINGTON - Insulin deficiency and hyperglycemia are two well-known culprits behind diabetes, both of which are reflected in blood glucose concentrations. Now, researchers are working to create ...

Jing Wang and his team at Empa and ETH Zurich usually work on measuring, analyzing and reducing airborne pollutants such as aerosols and artificially produced nanoparticles. However, the challenge the ...
