Anisotropy on notch-insensitive, optical, and swelling performances. a Ball plot of SNPP hydrogel with notches parallel and perpendicular to AgNP lamella and notch ratios from 0 to 50%. Error bars show the SD with sample size of 3. b UV-vis spectra of SNPP hydrogel with the incident light from two orthogonal directions. c Deformation ratio profiles of radius and height of hydrogel against time during the de-swelling and swelling process. The inset images show the cycling between the initial and de-swollen states
