  Nano-communication has gained significant attention in the last few years, as
a means to establish information transfer between future nano-machines.
Comparing with other communication techniques for nano-scale (calcium ions
signaling, molecular or catalytic nanomotors, pheromones propagation,
bacteria-based communication), the phenomenon called Forster Resonance Energy
Transfer (FRET) offers significantly smaller propagation delays and high
channel throughput. In this paper, we report our recent experiments on
FRET-based nano-networks performed in the Laboratory of Cell Biophysics of the
Jagiellonian University, Krakow. We propose to use Alexa Fluor dyes as nano
transmitters and receivers, as they enable to create multiple-input
multi-output (MIMO) FRET communication channels and thus enhance FRET
efficiency. We measure FRET efficiency values, calculate bit error rates for
the measured scenarios and extend the calculations to consider a general case
of MIMO (n,m) FRET channels.
