title: Hot punching of high-aspect-ratio 3D polymeric microstructures for drug delivery.
abstract: Hot punching with two different strategies has been demonstrated as a new method of fabricating high aspect ratio 3D microstructures for drug delivery. It has been shown that this process is highly versatile with good replication fidelity and yield.
