Various types of polymers can be used to create nanoparticles, including biodegradable polymers like polylactic acid (PLA), polyglycolic acid (PGA), and poly(lactic-co-glycolic acid) (PLGA). Non-biodegradable polymers such as poly(methyl methacrylate) (PMMA) and polystyrene are also used in certain applications. The choice of polymer depends on the desired properties and application of the nanoparticles.
