Scientists have determined the atomic crystal structure and functional mechanism of an enzyme essential for eliminating unwanted, non-nutritional compounds such as drugs, industrial chemicals, and toxic compounds from the body.
New research may lead to the development of a new breed of multimodal contrast agents that could work within a host of medical imaging platforms ? from ultrasound and computed tomography to magnetic resonance imaging and molecular imaging.
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.
