Nano-tetherball biosensor precisely detects glucose

(PhysOrg.com) -- Researchers have created a precise biosensor for detecting blood glucose and potentially many other biological molecules by using hollow structures called single-wall carbon nanotubes anchored to gold-coated ...

Biosensors: Sweet and simple

Surface-enhanced Raman spectroscopy (SERS) is a highly sensitive and versatile analytical tool that is widely used in biosensing applications. In conventional Raman spectroscopy, molecules are detected by their characteristic ...

Researchers use voltammetry to probe the brain's chemistry

(Phys.org)—Our brains are constantly awash in chemicals that serve as messengers, transporting signals from one neuron to another.  It's a really nifty system, although scientists still aren't clear on how, exactly, those ...
