Description:
Magnetotactic bacteria are a group of prokaryotic cells that orient and migrate along the geomagnetic field lines for their physiological functions and anaerobic/microaerophilic requirements. We report the use of magnetotaxis i.e. sensitivity towadrs megnetic field of Magnetospirillum magneticum as a functional component in very large scale integration (VLSI) design and fabrication. It is known that magnetotaxis arises out of a chain of magnetic nanoparticles within the bacterial cell that acts as a dipole. We propose a simple MATLAB based analysis and modeling of magnetic field acting on the chain of nanoparticles around a current carrying microwire. COMSOL was used to design the appropriate solenoid mesh containing the microwires.Our simulation results show that it is possible to manipulate the bacteria as "skilled workers" to transport select nanoparticles conducive to microchip fabrication. The use of magnetotactic bacteria may lead to the design of biomolecule based transformative integrated circuits well below the current feature size.
