A Fabrication of the hydrogel with boronate affinity via imprinting of SMMC-7721 cells for the capture and release of tumor cells. B Microscopy images of surface morphology of the imprinted hydrogel with fixed cells. C Cryo-scanning electron microscopy (SEM) of the nanostructures inside the imprinted hydrogel. D Schematic of the principle and procedure of controllable oriented surface imprinting of boronate affinity-anchored epitopes. E Transmission electron microscopy (TEM) image of the imprinting layer of silver NPs (AgNPs) imprinted with 60 min polymerization time.
