Introduction to Polymer Nanoparticles


Polymer nanoparticles (PNPs) are produced from a polymeric material with colloidal organic compounds in nanosize, and they have versatile applications due to their unique properties. These particles, composed of large macromolecules with repeating subunits, can range in size from around 100 nm to 1um. PNPs can be synthesized in nanosphere or nanocapsule shapes and structures. Polymer particles are increasingly becoming the subject of interest in various fields because of their unique properties and versatile applications. 


Production Methods of Polymeric Nanoparticles


Depending on the type of drug to be loaded in the polymeric NPs and their requirements for a specific administration route, different methods can be used to produce particles. No matter which preparation method is adopted, the products are usually obtained as aqueous colloidal suspensions.
