Monitoring Tissue Healing Through Nanosensors

Lei Yang and Thomas J. Webster

Abstract Nanotechnology is the use of materials with at least one dimension less than 100 nm. Nanotechnology has already revolutionized numerous fields, from construction to computers. Recently, nanotechnology has also been used to improve disease detection and treatment by developing wireless in situ sensors. Importantly, the use of wireless technologies in medicine, such as wireless body area networks and wireless personal area networks, is not new as they provide many promising applications in medical monitoring systems to measure physiological data from specific anatomical areas. Nanotechnology can aid in the functioning of wireless medical devices since it can provide for materials smaller in size (thus, minimally interacting with tissues to invoke an immune response), better in properties (such as electronic), and more similar to those of natural tissues since natural tissues are composed of nano-scale entities. In fact, studies have demonstrated increased tissue growth, decreased inflammation, and decreased infection of numerous nanoscale compared to currently used micron-scale materials. Due to the above, an ever-expanding range of therapeutic and diagnostic applications are being pursued by academic and industrial researchers. This chapter aims to provide a comprehensive review of recent developments in wireless sensor nanotechnology for monitoring and controlling cell responses.

Diabetes 2

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
