Abstract:
The performance of polymeric nanomaterials relies greatly upon their properties which are intimately related to the methods of fabrication of their materials. Among various synthetic polymers the polymers of 2-hydroxyethyl methacrylate (PHEMA) maintains a prime position in the biomedical field due to their useful physicochemical properties and suitability for controlled drug delivery applications. Furthermore, the addition of iron oxide to PHEMA nanoparticles imparts superparamagnetism to the nanoparticles and expands the range of their uses to include magnetic drug targeting applications. Here we focus on three methods for preparation of PHEMA nanoparticles, one by suspension polymerization, a second by emulsion polymerization without the use of any surfactants, and the final one with the incorporation of iron oxide into PHEMA nanoparticles.
