Wireless Communication Through Microtubule Analogue Device: Noise-Driven Machines in the Bio-Systems

摘要

Looking beyond ionic communication in bio-systems that is limited to a narrow band of kHz frequency domain is our objective. Microtubule, a vital subcellu-lar biomolecule found in almost all eukaryotic living systems, plays an important role in processing the cellular information. Therefore, here we introduce a microtubule analogue device, which wirelessly communicates with the neighboring microtubules and harvest energy from the noise present in the environment. The device is composed of spatially arranged lattice geometry with two different lattice parameters made of capacitors as tubulin protein analogue arranged on cylindrical shape structures. To demonstrate that the noise is harvested, both the devices are operated by noise, no ordered signal is applied in any measurement. Separation between both the devices is varied, while nearing the distance, the transmitted signal increases continuously and when they are taken further apart, the signal decreases gradually to null at ～ 140 cm. We image live, the generation and transmission of magnetic flux condensate between these two devices. This experiment is also repeated by inserting a magnetic shield 99.99% pure Ni sheet between two structures, which allows very less wireless transmission due to the shielding. The wireless communication frequency is in the range kHz-MHz.
