Dr. Joshua Zimmerberg, senior investigator of the National Institutes of Health, USA visited the Institute of Biophysics at the Chinese Academy of Sciences and delivered a lecture at the invitation of IBP director Professor XU Tao.
Researchers have created a unique core and shell nanoparticle that uses far less platinum yet performs more efficiently and lasts longer than commercially available pure-platinum catalysts at the cathode end of fuel-cell reactions.
The National Science Foundation's Major Research and Instrumentation (MRI) Program recently funded a $3.7 million NanoSIMS imaging mass spectrometer for 13 Arizona State University scientists and a large number of collaborators working on diverse topics involving both soft (biological) and hard materials (e.g. minerals).
The potential of nanotechnology to support biomedical applications, including techniques for intelligent diagnostics and therapeutics, probing and repairing of individual cells, nano-inspired implants, tissue engineering and regenerative medicine, is widely acknowledged. Find out more about current developments, network with other researchers and share research interests in a free online workshop on 'Nanotechnology for Biomedical Applications' organized by the ICPC Nanonet project on Friday May 28th.
Researchers explain how blasting silver nitrate solution with an electron beam can generate nanoparticles that are more effective at killing all kinds of bacteria, including gram-negative species that are not harmed by conventional antibacterial agents.
Using nanoporous silicon particles, two teams of investigators have created drug delivery vehicles capable of ferrying labile molecular therapies deep into the body. Both groups believe their new drug delivery vehicles create new opportunities for developing innovative anticancer therapies.
Researchers have created a targeted gold nanoparticle that appears to offer a more sensitive and accurate method for detecting early stage prostate cancer. These nanoparticles may also be useful for detecting lung and breast cancers, too.
Using a mixture of four quantum dots linked to antibodies that can detect cancer-associated proteins, a research team from Emory University has developed a method for mapping the molecular heterogeneity of human prostate tumor biopsies obtained from cancer patients. This method should be applicable to other types of tumors.
