Using gold nanoparticles to diagnose flu in minutes
By coating gold nanoparticles with antibodies that bind to specific strains of the flu virus and then measuring how the particles scatter laser light, the technology can detect influenza in minutes at a cost of only a fraction of a penny per exam.
Fluidigm Collaborates with BD Biosciences to Combine Cell Biology and Molecular Genetics for Single-Cell Research
Fluidigm Corporation announced today a collaboration with BD Biosciences, a segment of BD (Becton, Dickinson and Company), to co-host a public seminar series on the isolation and analysis of single cells.
Designing nanodiamond circuits for extreme environments
There is a new way to design computer chips and electronic circuitry for extreme environments: make them out of diamond.
Polymer’s hunt for nicotine
Newly synthesized polymer, fitted with molecular pincers of carefully tailored structure, effectively captures nicotine molecules and its analogues. The polymer can be used for fabrication of sensitive and selective chemical sensors to determine nicotine in solutions, and in the near future also in gases. Moreover, the polymer is suitable for slow, controlled release of nicotine, e.g., for therapeutic purposes.
NSF award to develop neural implants using graphene
Mark Ming-Cheng Cheng, Ph.D., assistant professor of electrical and computer engineering at Wayne State University, recently received a five-year, $475,000 Faculty Early Career Development (CAREER) grant from the National Science Foundation to study the potential of graphene, a novel carbon material, in the development of a reliable, high-performance, long-term implantable electrode system to improve quality of life using nanotechnology.

DNA strands that select nanotubes are first step to a practical ‘quantum wire’
Researchers describe how tailored single strands of DNA can be used to purify the highly desired 'armchair' form of carbon nanotubes.
Personal nanoparticle respiratory deposition sampler streamlines exposure assessment
Until more information becomes available on the mechanisms underlying nanomaterial toxicity, it is uncertain what measurement technique should be used to monitor exposures in the workplace. Many of the sampling techniques that are available for measuring airborne nano aerosols vary in complexity but can provide useful information for evaluating occupational exposures with respect to particle size, mass, surface area, number concentration, and composition. Unfortunately, relatively few of these techniques are readily applicable to routine exposure monitoring. That's why researchers have now developed a unique new sampler design that collects nanoparticles separately from larger particles in a way that mimics the respiratory system.
