This study is the first of its kind to successfully offer topical gene therapy without toxic effects.
Although the study did not report any side effects, Dr. Mark Abdelmalek, chief of the division of laser and dermatologic surgery at Drexel University School of Medicine believes that this type of nanotechnology can cause long-term problems in the human body.
"It's naive to expect that putting something like this in the body would have absolutely no side effects,” Abdelmalek said.
"It is temporarily changing the protein while the structure is in contact with the cells, but it doesn't permanently change the genetic defect," he said. "This is all brand new and exciting, but there's still many things we just don't know."
