Polymerized Pro‐Estrogen Microneedles via Two Photon Polymerization

open access: yesMacromolecular Rapid Communications, EarlyView.
Acrylic pro‐drugs of 17β‐estradiol were subjected to spatially controlled two‐photon polymerization to create bespoke microneedle geometries with potential biomedical applications for long‐term transdermal hormone delivery. ABSTRACT Two‐photon polymerization (TPP) is a powerful technique to create microscale structures with high precision, offering ...
