First paper comparing jet injection with tattooing techniques is online!

With the title High-speed imaging of solid needle and liquid micro-jet injections, it has been selected by the Editor of the Journal of Applied Physics as a Featured article.

we found that microjet injections are superior to solid injections in terms of energy and volumetric delivery efficiencies per injection for three different liquids.

In fact, we could reduce the environmental impact of used needles and benefit millions of people using needles for medical and cosmetic use… but more work is needed.
