In this paper, we present a cost-efficient and reliable route to produce polyurea xerogel (PolyU) as versatile carrier that provides high drug loading offers tuning over diclofenac (DCF) release profile. A simple one-pot reaction of an amino-terminated-polyether-PEO crosslinker, hexamethylene diisocyanate trimer-HDI, allow us obtain the polymeric networks. The gelation time during sol-gel react...
