Latest Colloidal gold Stories
SYRACUSE, N.Y., March 16, 2011 /PRNewswire/ -- Scientists in Syracuse University's Chemistry Department have created a new drug delivery system expected to advance the effectiveness of cancer-killing drugs.
Nanometer-scale gold particles are currently intensively investigated for possible applications in catalysis, sensing, photonics, biolabeling, drug carriers and molecular electronics.
Researchers at Case Western Reserve University have developed a little bomb that promises a big bang for cancer patients.
Scientists have created a diamond-like lattice composed of gold nanoparticles and viral particles, woven together and held in place by strands of DNA. The structure "“ a distinctive mix of hard, metallic nanoparticles and organic viral pieces known as capsids, linked by the very stuff of life, DNA "“ marks a remarkable step in scientists' ability to combine an assortment of materials to create infinitesimal devices. The research, done by scientists at the University of Rochester...
LONDON, December 21, 2010 /PRNewswire/ -- The World Gold Council (WGC) is delighted with the successful phase 1 clinical trial of a unique nanomedicine that uses nanoparticles of gold as the core of a delivery system for tumour targeted drug delivery.
A new study from researchers at North Carolina State University sheds light on how a technique that is commonly used for making single-metal nanoparticles can be extended to create nanoparticles consisting of two metals â€“ and that have tunable properties.
Gold nanoparticles, tiny pieces of gold so small that they can't be seen by the naked eye, are used in electronics, healthcare products and as pharmaceuticals to fight cancer.
Scientists can detect the movements of single molecules by using fluorescent tags or by pulling them in delicate force measurements, but only for a few minutes.
Researchers at Rensselaer Polytechnic Institute have developed a new, ultra-simple method for making layers of gold that measure only billionths of a meter thick.
A scientist at the US Department of Energyâ€™s (DOE) Argonne National Laboratory has created visible-light catalysis, using silver chloride nanowires decorated with gold nanoparticles, that may decompose organic molecules in polluted water.
