Caption: Organic materials chemist Shawn Dirk focuses a projector during work on neural interfaces, which are aimed at improving amputees' control over prosthetics with direct help from their own nervous systems. Focusing prior to exposing polymers ensures that researchers pattern the desired feature sizes for the interfaces.
