Tiny rulers to measure nanoscale structures
— 1 Sep 2010 09:59 | PhysicsWith the advent of nanometre-sized machines, there is considerable demand for stable, precise tools to measure absolute distances and distance changes. One way to do this is with a…
Ultrasensitive imaging method uses gold-silver 'nanocages'
— 13 Apr 2010 10:50 | TechnologyNew research findings suggest that an experimental ultrasensitive medical imaging technique that uses a pulsed laser and tiny metallic 'nanocages' might enable both the early detection…
Anticancer nanotech
— 16 Sep 2009 14:01 | HealthTiny particles of albumin, a protein found in the blood, can be used to carry radioactive isotopes to the site of a cancerous tumour in the body and so avoid many of the side-effects…
Hollow gold nanospheres show promise for biomedical and other applications
— 23 Mar 2009 13:58 | TechnologyA new metal nanostructure developed by researchers at the University of California, Santa Cruz, has already shown promise in cancer therapy studies and could be used for chemical and…
Targeted nanospheres find, penetrate, then fuel burning of melanoma
— 2 Feb 2009 08:32 | HealthHollow gold nanospheres equipped with a targeting peptide find melanoma cells, penetrate them deeply, and then cook the tumour when bathed with near-infrared light, a research team…
Engineering nanoparticles for maximum strength
— 21 Oct 2008 10:28 | TechnologyBecause they are riddled with defects, bulk crystalline materials never achieve their ideal strength; nanocrystals, on the other hand, are so small there's no room for defects. ('Nano'…
Novel technique sees into tissue at greater depth and resolution
— 17 Sep 2008 22:32 | HealthBy coupling a kicked-up version of microscopy with miniscule particles of gold, Duke University researchers are now able to peer so deep into living tissue that they can see molecules…
