Biodegradable Multifunctional Nanoparticles An effective drug delivery System The implementation of nanomaterials has been proven useful in fields spanning from molecular imaging, and molecular diagnosis, to targeted therapy in biomedical research. This variety may be accredited to the natural advantages given to these drugs in their composition. These nanomaterials have improved circulation times, enabled precise targeting, enhanced dissolution rates, and allow for enhance contrast when used as imaging agents- all from a change in partial size and encapsulation technique. Current methods of nanoparticle formation follow an extensive process of naturally occurring amalgamations between hydrophilic and hydrophobic components, leaving many aspects of particle formation unpredictable. This experiment explores a new approach to the formation of multifunctional Nanoparticles with the implementation of the Flash Nano-Precipitation (FNP) method; which, in a direct infusion between a hydrophobic drug-polymer mixture and water, creates the desired Nanoparticles nearly simultaneously upon infusion. Furthermore, this study tests the stability of these particles, and aims to display the ability of this method to precisely engineer aspects of these particles. In this heightened control of such nanoparticles, greater material efficiency is allotted. Moreover, the biodegradable properties of the polymers, and the methods of direct targeting available due to the nanoscale, allows for a lessened dosage of drugs that are harmful to the body (i.e. many drugs used in the treatment of cancer,) enabling a lessened use of chemicals both harmful to the body and the environment.
