3D nanoprinting prevents microneedle clogging in serial embryo injections

Researchers at the University of Maryland have demonstrated that nanoscale 3D printing can be used to fabricate high-aspect-ratio microneedles that eliminate clogging during embryo microinjection. The results, published in Nature Communications, show that additive manufacturing via two-photon laser writing enables precise, monolithic needle designs that outperform both conventional glass needles and printed controls in serial […]
