Dear Colleagues

In general, for every dollar we spent on acquiring a drug, we spent another dollar addressing its side effects. One technique to optimise drug side effects is using nanotechnology technique. The technique of nanoencapsulation of potential therapeutics was pioneered by Prof Thomas Chang at McGill University in the 1960s and 1970s as a way to overcome major obstacles in therapeutic delivery systems and to enable improved uptake of enzymes and drugs into the body where they can be used as a therapy for a medical disorder. Since then, the technology made significant advancement in various delivery systems, including within the hearing and balance disorders. This special issue aims to address various novel nanoencapsulation and bio-printing technologies for drug administration and targeted delivery.
