Magnetization hysteresis and AC susceptibility measurements were performed on the discontinuous metal–insulator multilayer [Co80Fe20(1.4 nm)/Al2O3(3 nm)]10. CoFe forms ferromagnetic single-domain particles being embedded in the Al2O3 matrix. Due to strong dipolar inter-particle interactions a ‘‘superferromagnetic’’ correlation of particle moments was previously stated. The dynamical magnetic pr...

A novel multiplexed sensing scheme based on Brownian relaxation for biomolecules tagged to magnetic nanoparticles (MNPs) in liquid environment is proposed. Feasibility of the technique has been verified by the experiments with the mixture of differently sized magnetic nanoparticles using a newly developed room temperature, miniaturized AC magnetic susceptometer. The AC magnetic susceptibility m...

In this article, the stress/stress sensing capability of FeSiB thin films is demonstrated and discussed. The relies on change in permeability by application stress, compressive tensile, DC magnetic field. This susceptibility/permeability was tested exciting field (AC) being same direction with applied stress. susceptibility shown to exhibit a maximal value at given critical Moreover, amplitude ...

Infection with Aspergillus terreus is more likely to result in invasive, disseminated disease when compared to other Aspergillus species; importantly this species appears to be less susceptible to the antifungal drug amphotericin B. Unique to this species is the ability to produce specialized structures denoted as accessory conidia (AC) directly on hyphae both in vitro and in vivo. With the hyp...

Antibody-functionalized magnetic nanoparticles dispersed in phosphate-buffered saline solution were used as reagents immunomagnetic reduction assays. Biomolecules are detected bioliquid samples when they associate with and reduce the AC susceptibility χ ac of reagent at a given frequency. In this study, chemical kinetics for real-time during association was investigated. The between biomolecule...
