Nanosensors and their Pharmaceutical Applications: A Review

Abstract

Nanotechnology research is rolling worldwide, having an impact on multiple sectors and with a general belief that medical and biological applications will form the greatest area of expansion over the next decade. This field is mainly driven by an endeavour to bring radical solutions to areas of medical need, not fulfilled presently. This article discusses the basic concepts and developments in the field of nanosensors and their applications in pharmaceutical and medicine fields. Various types of nanosensors including optical nanosensors, electrochemical nanosensors, chemical nanosensors, electrometers, biosensors, and deployable nanosensors are described. It describes the progression of this field of research from its birth up to the present, with emphasis on the techniques of sensor construction and their application to biomedical systems.
