Introduction to nanoparticles in pharmacy: A review

The creation of innovative medication delivery methods utilizing nanoparticles has seen an exponential increase in interest in recent years. When compared to traditional drug delivery methods, nanoparticles can provide substantial benefits in terms of high stability, high specificity, high drug carrying capacity, and the ability to for the capacity to deliver both hydrophilic and hydrophobic drug molecules, regulated release, and the ability to utilize in multiple administration methods. The classification, preparation techniques, characterization, application, benefits of nanoparticles, and health implications are the main topics of this paper. There are various instances where different methods can be used to analyse certain physical attributes. The difficulties in the reproducible and reliable characterization of nanomaterials must also be overcome by researchers from different domains, considering the growing importance of nanoparticles in basic research and applications following their synthesis and subsequent rounds of processing (like annealing). This review’s main goal is to provide an overview of the current state of knowledge on the application, developments, benefits, and drawbacks of a wide range of experimental approaches that can be used to characterize nanoparticles. According to the concept or group of the technique being used, the information they can supply, or the materials they are intended for, various characterization approaches are categorized.
