Abstract
Belonging to the field of tissue engineering, the invention in particular relates to a photoresponsive nanostructure film with high visible light transmittance and application thereof. The preparation method of the photoresponsive nanostructure film comprises the steps of: (1) dispersing photoresponsive nano-particles in water uniformly to form a nano-particle dispersion solution with a mass fraction of 10-20%; preparing the nano-particle dispersion solution, alcohol and an organic solvent into a precursor solution in a proportion of 0.02-0.06:6-9:1-3; and (2) adding the precursor solution onto a polystyrene culture vessel dropwise and evenly according to a concentration of 20-52 microL/cm<2>, and then conducting drying at 40-90DEG C, thus obtaining the photoresponsive nanostructure film with a grain size of 10-30nm, a thickness of 20nm-100nm and visible light transmittance of 89%-98%. Compared with the prior art, the method provided by the invention has the characteristics of high cell detachment efficiency, small cell damage, simple operation and wide applicable cell range, etc., thus having very strong practicability.
