Abstract: In this research on a novel application of electrospinning as a means of nanopatterning, iron oxide nanoparticles are being used to achieve nanopatterns on a glass substrate. Nanopatterning is a technique that can produce patterns with nanoscale details on surfaces. It is the fabrication of a nanoscale pattern, especially as a part of an electronic component that is widely used in the semiconductor industry. Electrospinning is a fast and simple process driven by the electrical forces on the surface of polymeric fluids, producing polymer filaments using an electrostatic force. This electrospinning technique can serve various purposes, such as the fine control of the fiber diameters, the production of a defect-free or defect-controllable fiber surface, and the formation of continuous single nanofibers. The patterns obtained play a crucial role in the operation as well as performance of the fabricated electronic, optical or magnetic device and the associated systems. The sample that we electrospun is a Magnetospirillum sp. strain AMB-1 (Magnetospirillum magneticum), which is a Gram-negative alpha-proteobacterium that synthesizes nano-sized magnetite crystals, otherwise known as magnetosomes, aligned intracellularly in a chain-like fashion. Several times electrospinning of the bacterial solution was done in order to set the optimization parameters i.e., by varying voltage, flow rate and the distance. By using electrospinning, the nanopatterns, of magnetite can be created for different applications such as growth of CNT’s, magnetic recording, as well as flexible electronics.
