Abstract: A method for expansion, cutting, and microscopic imaging and a superabsorbent hydrogel applicable in the method. The method is: applying an expansive substance to a biological tissue to be imaged, under the effect of the expansive substance, allowing the biological tissue to expand into an expanded tissue of which the hardness is no less than 15 kPa, and then, combined with mechanical cutting, cutting and imaging the expanded tissue, thus implementing three-dimensional expansion, cutting, and microscopic imaging of the biological tissue, and implementing three-dimensional super-resolution imaging. The method, by controlling the requirement on the hardness of the biological tissue under the effect of the expansive substance, combined with a subsequent process of repeated cutting-imaging, effectively solves the restriction on tissue thickness for super-resolution imaging and the problem of image drifts due to the tissue being soft, difficult to cut, and prone to slippage, and implements three-dimensional super-resolution imaging of a thick biological tissue that is difficult to attain with the prior art.
