Self-assembly and hydrogel formation of QDHs. a Native PAGE analysis to verify self-assembly of the QD-DNA and Y-shaped DNA nanostructures: Lane 1: Y1; lane 2: Y1 + Y2; lane 3: Y1 + Y2 + Y3; lane 4: DNA-TWJ + QD-DNA; lane 5: DNA ladder. b Photographs of QDHs under irradiation with ambient light and ultraviolet light. c Frequency sweep test were carried out between 0.05 and 500 rad/s at a fixed strain of 5% for the three color hydrogels. SEM images of DNA hydrogels with low resolution (d) scale bar: 500 μm and high resolution (e) scale bar: 500 nm
