a Schematic of the synthesis process. b Photographs of the DNA solution before and after crosslinking. Scale bar: 1 cm. c SEM image of DNAgel. Scale bar: 100 μm. d G′ and G″ of DNAgel on strain amplitude sweep. e ATR-FTIR analysis of pure salmon sperm DNA and DNAgel. f Images of water droplet absorbed by DNAgel. Scale bar: 1 mm. g Representative photographs of DNAgel in 2D and 3D shape during swelling process. Scale bar: 2 cm. h Mask Cutting, i macromolding for macro manufacturing (Scale bar: 2 cm) and j micromolding for micro-manufacturing (Scale bar: 2 mm) to obtain DNAgel in diverse shapes. Representative images are shown from three (b, c, f–j) independent experiments with similar results. Source data are provided as a Source Data file.
