Fig. 1From: Injectable PTHF-based thermogelling polyurethane implants for long-term intraocular applicationA Synthesis of thermogelling polyurethanes with PTHF. The degree of PTHF conjugation can be varied by changing feed ratios. B Schematic for thermogels based on bioinert PTHF for intraocular application. These hydrogels are sustainably sourced with low cytotoxicity and long-term in situ supportsBack to article page
