Signal generation and storage in FRET-based nanocommunications

摘要

The paper is concerned with Forster Resonance Energy Transfer (FRET) considered as a mechanism for communication between nanodevices. Two solved issues are reported in the paper, namely: signal generation and signal storage in FRET-based nanonetworks. First, luciferase molecules as FRET transmitters which are able to generate FRET signals themselves, taking energy from chemical reactions without any external light exposure, are proposed. Second, channelrhodopsins as FRET receivers, as they can convert FRET signals into voltage, are suggested. Further, medical in-body systems where both molecule types might be successfully applied, are discussed. Luciferase-channelrhodopsin communication is modeled and its performance is numerically validated, reporting on its throughput, bit error rate, propagation delay and energy consumption.
