Fig. 2: Fabrication results for esDLW-based 3D printing of microinjection needles directly atop fused silica glass capillaries.
From: 3D nanoprinting of embryo microinjection needles with anti-clogging features
a–c 3D needle tip designs. d–f Control tip designs. a, d Computer-aided manufacturing (CAM) simulations, and b, e corresponding micrographs captured during the esDLW printing process. Scale bars = 100 µm (See also Supplementary Movie S1; Supplementary Movie S2). c, f Scanning electron microscope (SEM) images of representative printing results. Scale bars = 100 µm (Expanded views = 10 µm). g,h SEM micrographs of printed integrated microporous filters. g Sectioned view. Scale bar = 100 µm (Expanded view = 25 µm). h Bottom view. Scale bar = 25 µm
