Laser-Assisted Nanomaterials Fabrication from Thin Films for Magnetic Biosensors
Laser nanostructuring is a powerful tool to produce different nanomaterials such as nanoparticles and surface relief structures. It was shown that pulsed laser ablation of thin 250 nm Fe film in acetone allows obtaining core-shell Fe@FeO nanoparticles with a mean size of 90 nm. Fabrication of femtosecond laser-induced periodic surface structures on a Si substrate surface with subsequent deposition of a NiFe/IrMn exchange-biased bilayer causes the appearance of an additional out-of-plane magnetization component with keeping exchange bias. Obtained nanomaterials look promising for designing magnetic biosensors with an improved detection limit.
