a Schematic representation of sound assisted patterned hydrogel formation and selective cell growth. GOx: glucose oxidase, TA-AuNP: thioctic acid-functionalized gold nanoparticle, PEG-DA: poly(ethylene glycol)-diacrylate. b Time-dependent images during the formation of a concentric ring pattern obtained by applying 40 Hz of audible sound and preparation of patterned hydrogel (scale bar is 10 mm). c A photograph of the patterned hydrogel (scale bar is 10 mm). d HeLa cell growth pattern on the hydrogel (scale bar is 5 mm). e 3D fluorescence intensity plot of the region-specific cell growth pattern.
