Polymeric Nanoparticles in Drug Delivery

Abstract

Polymeric nanoparticles (PNPs) are tiny particles with a size between 1 and 1000 nm that can include active substances that have been surface-adsorbed over onto polymeric core or are entrapped inside of them. Both nanospheres and nanocapsules fall under the umbrella of “nanoparticles,” which are characterized by their morphological structure. This material is anticipated to be extensively used in various sectors, including drug delivery systems, catalysts, biosensors, nanocomposites, agriculture, and the environment because of its extremely small size and large surface area. Particle size, geometry, material selection, and processing methods are all study topics of interest to establish the optimal nanosystem for more efficient and focused delivery of therapeutic applications. Drug delivery methods such as drug conjugation and drug entrapment, prodrugs, stimuli-responsive systems, imaging modalities, and theranostics all use PNPs. The goal of the technique of using polymeric nanoparticles for drug delivery is to maximize therapeutic effectiveness while reducing side effects.
