Several types of polymers are used to create PNPs, including: - Polylactic acid (PLA) - Polyglycolic acid (PGA) - Poly(lactic-co-glycolic acid) (PLGA) - Polycaprolactone (PCL) - Chitosan and other natural polymers
These polymers are chosen based on their biocompatibility, biodegradability, and mechanical properties.
