Latest Colloidal gold Stories
Using tiny gold particles and infrared light, MIT researchers have developed a drug-delivery system that allows multiple drugs to be released in a controlled fashion.
U.S. scientists say they have developed a method that makes and patterns nanoscale wires and other devices now made with expensive lithographic tools.
By Valenzuela, Stella Cortie, Michael Gold nanoparticles can target and kill the parasite Toxoplasma gondii, opening the way for a new treatment for parasitic infections in humans. Over the ages, people worldwide have revered gold as a precious metal, with its uses being many and varied.
Nanoparticles of gold too small to be seen with the naked eye have been created in laboratories, but up until now, have never been seen in nature.
By Jain, Kewal K Background: Nanobiotechnologies are being applied to molecular diagnostics and several technologies are in development. Methods: This review describes nanobiotechnologies that are already incorporated in molecular diagnostics or have potential applications in clinical diagnosis.
By Xiao, Yabing Ling, Jie; Qian, Shahua; Lin, Anqing; Et al ABSTRACT: A novel method of preconcentration of trace arsenite and arsenate by using titanium dioxide nanoparticles as adsorbent was described.
The future of cancer detection and treatment may be in gold nanoparticles â€“ tiny pieces of gold so small they cannot be seen by the naked eye.
The speed of nanoparticle assembly can be accelerated with the assistance of the molecule that carries lifeâ€™s genetic instructions, DNA, a team of researchers at the U.S. Department of Energyâ€™s Brookhaven National Laboratory recently found.
Nanomaterials are increasingly gaining the attention of not only the scientific community, but also the public due to their unique properties which endear them to new and exciting applications. These special properties can vary markedly from those of the analogous bulk materials.
A team of 13 U.K. researchers and one U.S. researcher reported in the Oct. 20 issue of the British journal that the carbon-supported gold catalysts can be fine-tuned with high selectivity for desired products through the addition of trace amounts of bismuth.
