The present and future of nanotechnology in human health care

摘要

Nanotechnology is a multidisciplinary field that covers a vast and diverse array of devices derived from engineering,physics,chemistry,and biology.The burgeoning new field of nanotechnology,opened up by rapid advances in science and technology,creates myriad new opportunities for advancing medical science and disease treatment in human health care.Applications of nanotechnology to medicine and physiology imply materials and devices designed to interact with the body at subcellular (i.e.,molecular) scales with a high degree of specificity.This can be potentially translated into targeted cellular and tissue-specific clinical applications designed to achieve maximal therapeutic efficacy with minimal side effects.In this review the chief scientific and technical aspects of nanotechnology are introduced,and some of its potential clinical applications are discussed.
