Single-walled carbon nanotubes (SWCNTs) can kill bacteria like the common pathogen E. coli by severely damaging their cell walls, according to a recent report from Yale researchers in the American Chemical Society journal Langmuir.
A vaccine against anthrax that is more effective and easier to administer than the present vaccine has proved highly effective in tests in mice and guinea pigs, report University of Michigan Medical School scientists in the August issue of Infection and Immunity.
Purdue University researchers have developed new miniature devices designed to be implanted in the brain to predict and prevent epileptic seizures and a nanotech sensor for implantation in the eye to treat glaucoma.
Finding out whether that unusual sore in your mouth is cancerous should become a lot faster and easier in the years ahead. Scientists supported by the National Institute of Dental and Craniofacial Research (NIDCR), part of the National Institutes of Health, have engineered the first fully automated, all-in-one test, or lab on a chip, that can be programmed to probe cells brushed from the mouth for a common sign of oral cancer.
University of Surrey researchers, Dr Alan Dalton and Dr Richard Sear, have received grants totalling ?100k from the SETsquared Applied Collaborative Research Programme and the EPSRC to support collaborative work with the University of California, Irvine, researching the use of nanomaterials in stem cell growth.
Ram Devireddy, assistant professor of mechanical engineering at LSU, recently co-authored an article with Todd Monroe, assistant professor of biological and agricultural engineering, investigating the complex effects of nanoparticles on cell freezing. The report was published in the prestigious journal Nanotechnology.
Researchers at Purdue University have shown that common bacteria can deliver a valuable cargo of “smart nanoparticles” into a cell to precisely position sensors, drugs or DNA for the early diagnosis and treatment of various diseases.
The Methodist Hospital, the University of Houston, and Weill Cornell Medical College of Cornell University are combining their expertise in biomedical imaging to advance discoveries in this growing field of biomedical science and its clinical applications.
Regulatory oversight of nanotechnology is urgently needed and the Environmental Protection Agency (EPA) should act now, reports a new study released today.
Drug delivery systems have progressed from the teaspoon to time-release capsules to drug-eluting stents.
