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 ...

Mass spectrometry imaging of N‐linked glycans: Fundamentals and recent advances

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract With implications in several medical conditions, N‐linked glycosylation is one of the most important posttranslation modifications present in all living organisms. Due to their nontemplate synthesis, glycan structures are extraordinarily complex and require multiple analytical techniques for complete structural elucidation.
