In work that unmasks some of the magic behind memristors and 'resistive random access memory', or RRAM, researchers have shown that the metal particles in memristors don't stay put as previously thought.
Using the stuff of sand, silicon dioxide, as a binding layer for replacement bone prosthetics could allow more biocompatible artificial joints to be manufactured as well as reducing the risk of post-operative infection.
A multi-institutional research team has received a $480,000 National Science Foundation grant to build an inexpensive device that uses nanotechnology and a simple urine test to detect the most miniscule amount of bladder cancer cells in a patient.
Current drug-delivery systems used to administer chemotherapy to cancer patients typically release a constant dose of the drug over time - but a new study challenges this 'slow and steady' approach and offers a novel way to locally deliver the drugs 'on demand'.
The molecular building blocks that make up DNA absorb ultraviolet light so strongly that sunlight should deactivate them - yet it does not. Now scientists have made detailed observations of a 'relaxation response' that protects these molecules, and the genetic information they encode, from UV damage.
The contest supports the atmosphere of discovery and wonder that nanoscience and nanotechnology research represent. The first objective of this competition is for participants to have fun. The second objective is to promote the public interest and acceptance of nanos: people new to the subject really begin to understand it when they see compelling pictures.
