Study and Analysis of Thermal Behavior of Human Red Blood Cells Due to in-vivo Optical Communication
MetadataShow full item record
In-vivo nano-sensor networks primarily consist of nano-sized particles which are able to communicate amongst themselves inside the body in real time. In-vivo wireless nano sensor networks have opened the gateway for various medical application. While in-vivo nano-sensors have helped in the development of various health monitoring applications, the nano-channels have helped in various drug delivery applications. At the nanoscale range, acoustics communication has exploited the ultrasonic waves. At the same time, molecular communication has also been exploited where chemical and biological nanosensors have been used for health monitoring and detection of diseases. Exploitation of terahertz waves for the operation of the nanoscale devices have been in practice. But it has its limitations in its in-vivo use since the high freuency terahertz waves leads to water absorption, therefore having negative impact on the cells. Hence, optical window is proposed as a promising frequency range for intra-body wireless communication as they have suitable wavelengths to build nano-antennas. Additionally, absorption is minimal at optical frequencies for in-vivo communication. But the propagation of light generates heat and extreme heating can lead to the deformation of tissues which are unwanted. Thus, we propose a method of optical communication at the cell level without any adverse thermal impact on the blood cells that can help in further health monitoring through imaging without any adverse effect on the individual cells.The research aims at providing a preceding insight into the possibility of communication at desired data rate without affecting surrounding environment.
