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 ...

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 ...

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 ...
