Experimental Studies on a Single Microtubule: Investigation of Electronic Transport Properties
Presented by Anirban Bandyopadhyay
October 22, 2010
ABSTRACT
Using
nanotechnology we have studied electronic transport properties of a
single microtubule (MT) under direct current/bias (DC) and alternating
current (AC) of varying frequencies. Our study ranged from 10 K to the
room temperature. At specific, 1) spontaneous MT growth under AC signal
that led to Froelich Condensation, 2) ballistic electronic transport
under DC and AC signal, 3) ferroelectric MT properties under DC signal.
Applications of MT as a multilevel information processing and memory
device (beyond binary logic) will be discussed. I will present our
rigorous study to unravel the origin of room temperature coherent
transport in terms of band energy diagrams where point contacts between
valence and conduction band triggers transport of electrons/quasi
particles. Finally, I will describe challenges and resolution of
detection of MT topological qubits based on Hemchandra/Fibonacci MT
geometry at physiological temperature.
About the speaker: Dr.
Anirban Bandyopadhyay completed his doctorate in supramolecular
electronics at IACS, Kolkata, India, in 2005. He is a permanent
scientist in NIMS, Tsukuba Japan. In 2008, he and his colleagues
invented nano brain an artificial molecular processor that mimics a
fundamental hardware feature of our neural network. Apart from holding
executive positions in particular scientific organizations and editorial
board of information related journals, he is involved in setting up a
global platform for creating a super-intelligent molecular machine
"Bramha". For details about his works, and publications please visit
