Role of nanotechnology in biomedical applications: an updated review

Abstract

The particles in nanometre size can be developed to provide opportunities for research for developing specific and highly selective drug delivery systems or biosensors which are highly used in biomedical research. Nanoparticles are smaller in size and can cross the blood-brain barrier easily because of their size, this unique property can be utilized for developing novel drug delivery systems and modern biosensors with higher specificity. In this current review, we discuss the history and various types of preparation and applications of nanotechnology in different fields.
