Förster rezonans enerji transferi (FRET) tabanlı nano-haberleşme

Nanoscale communication is a novel and quite interdisciplinary research area which aims to design and develop communication networks among nano-size machines to extend their limited capabilities for groundbreaking biomedical, industrial and environmental applications. In this thesis, we propose and investigate a novel nanoscale wireless communication method based on a physically realizable phenomenon, F örster Resonance Energy Transfer (FRET) which is observed among fluorescent molecules such as semiconductor nanoparticles and organic dyes. Based on the well-established theory of FRET, we first information theoretically model FRET-based point-to-point communication channel between a single pair of fluorophore-based nanomachines with single-exciton transmission scheme. Furthermore, we analyze the performance of FRET-based point-to-point and broadcast nanoscale communications with multi-exciton transmission scheme performing realistic Monte Carlo simulations. We also propose a long range nanoscale communication channel based on multi-step FRET. We develop electrically and chemically controllable information routing techniques that are applicable to FRET-based nanonetworks. Moreover, we analyze FRETbased mobile molecular nanonetworks deriving analytical models for FRET-based mobile ad hoc molecular nanonetworks (FRET-MAMNET) and FRET-based mobile molecular sensor/actor nanonetworks (FRET-MSAN). Lastly, we perform an experiment in which we achieve to transfer data with the transmission rates of 50, 150 and 250 kbps through the mixture of Fluorescein and Rhodamine B as the donor/acceptor pair. This experiment is one of the rst physical realizations of communications at nanoscale.
