Thermogelling chitosan (CS)/glycerophosphate (GP) solutions have been reported as a new type of parenteral in situ forming depot system. These free-flowing solutions at ambient temperature turn into semi-solid hydrogels after parenteral administration. Formulation parameters such as CS physico-chemical characteristics, CS/gelling

Polysaccharides are a new class of pervasive biopolymers that display many advantages including wide availability, sustainability, inherent inclusion of chemical functionality, biocompatibility and biodegradability. Current efforts are focused on the catalytic transformation of these macromolecules into fuels and platform chemicals.
