The injectable polymer solution, usually precursor formulation, is injected into the defect site by using injection tools. This solution conforms defect site and crosslink upon injection, enhancing control over scaffold formation . A recent breakthrough in biomaterial research has been introduced, exploring stimuli responsive materials that gel upon some physical stimuli like light, temperature, pH, chemical signals, enzymes, or mechanical stress . This in situ gelation method involves triggering gel formation within the body using external factors, e.g. light sensitive polymers are injected and it crosslinks within the body on exposure to specific light wavelength enabling precise, localized gelation. This method can enhance the control over conformation and scaffold behavior .
