3D‐Printed Microinjection Needle Arrays via a Hybrid DLP‐Direct Laser Writing Strategy (Adv. Mater. Technol. 5/2023)

Direct Laser Writing In article number 2201641, Ryan D. Sochol and co-workers present a hybrid additive manufacturing strategy for 3D nanoprinting arrays of hollow, high-aspect-ratio microneedles at unprecedented scales. Microneedle array-mediated injections of microfluidic cargo into mouse brains yield distributed delivery over a large coverage area, holding unique promise for emerging biomedical microinjection applications such as treatments of neurological conditions.
