Inspired by the hairs on honey bee legs that enable them to transport large quantities of pollen grains, we have developed microfabricated surfaces covered with hair-like micropillars capable of efficiently entrapping micron-sized particles at about 5 times greater density than commercially available drug patches; these surfaces could be used to develop drug patches grabbing higher drug contents, finding other applications in biotechnological, biomedical, and industrial fields.

This work was published on the prestigious journal Proceedings of the National Academy of Science.
