John Toon, Georgia Institute of Technology The annual ritual of visiting a doctor's office or health clinic to receive a flu shot may soon be outdated, thanks to the findings of a new study published in the journal Vaccine. The research, which involved nearly 100 people recruited in the metropolitan Atlanta area, found that test subjects could successfully apply a prototype vaccine patch to themselves. That suggests the self-administration of vaccines with microneedle patches may one...

Drug delivery technique Using chemical "nanoblasts" that punch tiny holes in the protective membranes of cells, researchers have demonstrated a new technique for getting therapeutic small molecules, proteins and DNA directly into living cells. Carbon nanoparticles activated by bursts of laser light trigger the tiny blasts, which open holes in cell membranes just long enough to admit therapeutic agents contained in the surrounding fluid. By adjusting laser exposure, the researchers...

Researchers at Georgia Institute of Technology and Emory University have invented a painless vaccine-delivery system that may one day allow flu shots to be delivered by mail.  The new system replaces a conventional large needle with hundreds of tiny dissolvable ones embedded in a skin patch, and may even generate a better immune response than a conventional shot. The microneedles come attached to a Band-Aid like skin patch, and are so small they cannot be felt.  They scarcely...

Good news for people fearful of needles and squeamish of shots: Scientists at the 238th National Meeting of the American Chemical Society report the design of a painless patch that may someday render hypodermic needles "” as well as annual flu shots "” a thing of the past. Lined with tiny "microneedles," these patches could make treatment of diabetes and a wide range of other diseases safer, more effective and less painful. Used as tiny hypodermic needles, they could improve...

LEXINGTON, Ky. -- In what is believed to be the first peer-reviewed study of its kind involving human subjects, researchers at the University of Kentucky College of Pharmacy and the Georgia Institute of Technology have demonstrated that patches coated on one side with microscopic needles can facilitate transdermal delivery of clinically-relevant doses of a drug that normally cannot pass through the skin. Reported in the journal Proceedings of the National Academy of Sciences, the study...

WASHINGTON (Reuters) - Ultrasound energy can briefly open a door into cells to let drugs and other compounds inside, U.S. researchers reported on Tuesday in a study that could lead to improvements in medical care. Ultrasound causes the violent collapse of bubbles, which in turn creates enough force to open holes in the outer membranes of cells, the team at the Georgia Institute of Technology and Emory University in Atlanta reported. The holes, which close quickly, allow the entry of...
