a) Bioactivity evaluation of HRP‐doped silk resist and HRP enzyme after UV exposure. The ELISA test shows that enzyme activities are negatively affected during UV exposure (as shown in the photos on the right) and silk resists can help to stabilize the bioactivities to some extent during UV exposure; b) portion of the designed photomask. c–f) Double immunofluorescence staining with Nestin (green fluorescence) and nuclear staining (blue DAPI staining) of fetal neural stem cells cultured on UC–LC substrates showing the spatial guidance of cell seeding. Scale bar: 100 µm.
