Abstract: Compositions and methods for preparing and using a swellable polymer network for expansion microscopy (ExM) applications. The swellable polymer network can be prepared on demand using external stimuli for ExM applications. A variety of external stimuli can be employed, including light irradiation, pH, temperature, and magnetic fields. Network preparation using light irradiation is particularly advantageous, as it allows tuned control over the network properties through the variation of time and dose of light irradiation. In other words, light irradiation can be employed with a wavelength and intensity that enables a polymer network formation.

Abstract: Compositions for tissue engineering and drug delivery have been developed based on solutions of two or more polymers which form semi-interpenetrating or interpenetrating polymer networks upon exposure to active species following injection at a site in a patient in need thereof. The polymers crosslink to themselves but not to each other; semi-interpenetrating networks are formed when only one of the polymers crosslink. The resulting viscous solutions retain the biologically active molecules or cells at the site of injection until release or tissue formation, respectfully, occurs. As a result of studies conducted with polymer-cell suspensions forming interpenetrating polymer networks, it has been determined that polymer solutions can be formulated wherein the active species is provided by exposure of the polymer solution to an exogenous source of active species, typically electromagnetic radiation, preferably light.
