The topic of nanotechnology is one that is expanding quickly and has the potential to transform a number of scientific disciplines, including medication research. Researchers can develop new medications that are safer, more precise, and effective than current treatments by manipulating matter at the nanoscale level. The application of nanotechnology to the discovery of new drugs is more promising than ever in 2023. The creation of targeted medication delivery systems is one of the most intriguing uses of nanotechnology in the drug discovery process. The efficiency of the treatment is increased while the risk of adverse effects is reduced by these methods, which employ nanoparticles to deliver medications specifically to particular cells or tissues. For instance, scientists have created nanoparticles that, when required, may directly deliver medications to tumors and pass the blood-brain barrier.
