Drug delivery refers to the process or method of providing a pharmaceutical substance to a human or animal for obtaining a therapeutic effect. Nanomaterials are frequently utilized in pharmaceuticals and medicine due to their unique optical, mechanical and electrical properties. They are also used for developing novel therapeutics, detecting biological molecules and imaging of sick tissues. Emerging technologies such as MEMS, 3DP and MF have been studied for the production of diagnostics or drug delivery systems. These technologies have the potential to fight pandemics by offering a preventive, predictive and personalized (3P) medical approach. New technologies allow for the creation of devices that are simpler to use, which can monitor or diagnose a condition quickly, as well as control the release of biologics or drug molecules. The topics covered in this extensive book deal with the emerging materials and technologies in drug delivery. It provides significant information to help develop a good understanding of the recent studies in this field. The readers would gain knowledge that would broaden their perspective in this area of pharmaceutical science.
