The paper is concerned with Förster 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.

本文关注的是Förster共振能量转移（FRET），它被认为是纳米设备之间进行通讯的一种机制。本文报告了两个已解决的问题，即：基于FRET的纳米网络中的信号生成和信号存储。首先，提出了萤光素酶分子作为FRET发射体，其能够自身产生FRET信号，并从化学反应中吸收能量而没有任何外部光暴露。其次，建议使用通道视紫红质作为FRET接收器，因为它们可以将FRET信号转换为电压。此外，还讨论了可能成功应用两种分子类型的医疗体内系统。对萤光素酶-通道视紫红质的通信进行了建模，并对其性能进行了数值验证，报告了其吞吐量，误码率，传播延迟和能耗。
