A Needle From a Future Doctor You Probably Won't Notice...
"We were able to fabricate hollow, plastic microneedles using a laser-based rapid-prototyping approach," says Dr. Roger Narayan, one of the lead researchers, "and found that we could deliver a solution containing quantum dots using these microneedles.
"The motivation for the study was to see whether we could use microneedles to deliver quantum dots into the skin," Narayan says. "Our findings are significant, in part, because this technology will potentially enable researchers to deliver quantum dots, suspended in solution, to deeper layers of skin. That could be useful for the diagnosis and treatment of skin cancers, among other conditions."
