Drug discovery is a complex, lengthy and also expensive process of inventing a new medication in the field of pharmaceuticals, biotechnology and pharmacology for saving lives. Drug discovery involves stages namely, target identification, target validation, high-speed screening and lead optimization. A drug that cannot be delivered properly to its site of action is definitely useless.
Many scientists are pursuing ways to treat disease and finding ways for drug delivery methods. A team of scientists from University of Florida had conducted research on the drug-delivery vehicles to test the nanoparticles movement. Also, Washington University scientists are aimed to research on the speeding the development of novel drugs to treat rare diseases in the fields of cancer science, immunology, neuroscience, cardiology. Researchers at the Institute of Bioengineering and Nanotechnology and IBM have demonstrated sustained drug delivery using a hydrogel resulted in significant tumor size reduction size.
The demand of drug usage is increasing rapidly. A faster and safer method of drug delivery is the aim of drugs. Pharmaceutical and biotechnology industries are more relied on the advanced technologies with the use of nanobiotechnology in order to speed up the development of new drugs. Nanotechnology will be applied through all the drug developmental stages starting from formulations for optimal delivery till the clinical trials for diagnostic applications. Nanotechnology based assays will enable high-throughput cost-saving screening. The most important pharmaceutical applications of nanotechnology are in drug delivery, providing improved intracellular delivery possibilities. Nanosubstances like fullerenes could be potential drugs for the future generations.
