Nanomedicine in sensing, delivery, imaging and tissue engineering: advances, opportunities and challenges

Engineered nanomaterials are at the forefront in rapidly emerging field ‘nanomedicine’, and are offering exciting opportunities in healthcare. The nanomaterials acquire remarkable potential due to their unique physicochemical properties at nanoscale, making them suitable for medicinal usages. In this chapter, we aim to highlight on advances, opportunities and challenges in nanomedicine, herein special emphasis is given on important aspects of sensing, delivery, imaging and tissue engineering. We further hypothesize that fundamental understanding of the interactions between nanomaterials and biological systems may provide a foundation for engineering the next generation nanoscale devices for a range of medicinal usages.
