A nanoparticle-based drug delivery concept in which an applied magnetic field directs the accumulation in tumor cells of custom-designed, drug-filled nanocarriers has been demonstrated by University at Buffalo researchers.
University of Arkansas researchers have created assemblies of nanowires that show potential in applications such as armor, flame-retardant fabric, bacteria filters, oil cracking, controlled drug release, decomposition of pollutants and chemical warfare agents.
Imagine an implantable device that could be programmed to release exact numbers of drug-laden nanoparticles at specific times over the course of weeks or months or even in response to incoming biochemical signals.
A team of investigators describes its use of plasmon resonance spectroscopy to detect the release of individual gold nanoparticles that are cleaved from a surface through the activity of a target enzyme.
The National Institute of Advanced Industrial Science and Technology (AIST) and Tohoku University have theoretically and experimentally analyzed the crystal nucleation process and the subsequent crystal growth process in the colloidal synthesis of CdSe quantum dots.
Biobarcoded nanoparticles, which up until now have proven useful only for detecting mutations one at a time, can be used in a multiplexed system to detect and distinguish among four different DNA sequences simultaneously
According to the findings of the Federal Institute for Risk Assesment (BfR) in Germany, nanoparticles are not the cause of the health disorders, in some cases severe, which occurred after using so-called sealing sprays.
Nanowires made of semiconductor materials are being used to make prototype lasers and light-emitting diodes with emission apertures roughly 100 nm in diameter?about 50 times narrower than conventional counterparts.
Bombarding a carbon nanotube with electrons causes it to collapse with such incredible force that it can squeeze out even the hardest of materials, much like a tube of toothpaste, according to an international team of scientists
