Purdue University researchers have created a drug delivery method using silicon nanoneedles with diameters 100 times smaller than a mosquito’s needle. These nanoneedles are embedded in a stretchable and translucent elastomer patch that can be worn on the skin to deliver exact doses directly into cells.

Minimally invasive patch delivers exact doses directly into cells, lessens pain, toxicity. Purdue University researchers have developed a new flexible and translucent base for silicon nanoneedle patches to deliver exact doses of biomolecules directly into cells and expand observational opportunities.
“This means that eight or nine silicon nanoneedles can be injected into a single cell without significantly damaging a cell...
