New biosensor is based on a nanowire crystal array

(PhysOrg.com) -- A quick, inexpensive and highly sensitive test that identifies disease markers or other molecules in low-concentration solutions could be the result of a Cornell-developed nanomechanical biosensor, which ...

Paper strips can quickly detect toxin in drinking water

(PhysOrg.com) -- A strip of paper infused with carbon nanotubes can quickly and inexpensively detect a toxin produced by algae in drinking water. Engineers at the University of Michigan led the development of the new biosensor.

Graphene-DNA biosensor selective, simple to create

(PhysOrg.com) -- Graphene and DNA can combine to create a stable and accurate biosensor, reports a study published in the nanotechnology journal Small. The tiny biosensor might eventually help doctors and researchers better ...

Picture this—biosecurity seen from the inside

When plants come under attack internal alarm bells ring and their defence mechanisms swing into action - and it happens in the space of just a few minutes. Now, for the first time, plant scientists - including experts from ...

Forget your password: The future is 'passthoughts'

(Phys.org) —Instead of typing your password, in the future you may only have to think your password, according to School of Information researchers. A new study explores the feasibility of brainwave-based computer authentication ...
