A Microneedle Patch That Can Melt Fat...From Mice

18 September 2017

Imagine being able to apply a patch capable of dissolving fat to any part of your body. Thanks to researchers from Columbia University and the University of North Carolina, such a patch is now a reality…at least for mice.

When applied to mice during the study, microneedles mounted on a patch carried nanoparticles of medicine to the treated areas, reducing fat by up to 20 percent.

Researchers believe that the patch will eventually help in the fight against diseases such as diabetes and obesity and will have major implications for the field of cosmetic surgery—once it is determined safe for humans.

"Many people will no doubt be excited to learn that we may be able to offer a noninvasive alternative to liposuction for reducing love handles," said pathologist Li Qiang from Columbia University.

For now, the researchers will continue to review what combinations of medicine are the safest and most effective.

The findings were published in the journal ACS Nano.
