Overview of Nanotechnology Applications in Healthcare

Microorganisms gaining drug resistance, difficulty in disease screening, unavailability of point-of-care diagnostic tools are few challenges in the healthcare industry. Over the past few decades, much research has been directed towards developing new nanomaterials with tunable properties for diverse applications in biomedicine, bioimaging, disease diagnosis, therapeutic formulations, etc. Nanosystems specifically used in the healthcare sector include specially designed and functionalized nanomaterials for suitable applications. Nanotechnology finds important applications in identification of specific types of cancers even before their onset, identification of specific infections, targeted gene and drug delivery systems, etc.
