“…A feasible solution to these issues currently under investigation involves coating the magnetic nanoparticles with organic or inorganic materials to form core-shell nanostructures (16)(17)(18)(19)(20). In the present study, silica was adopted to coat iron-cobalt material, primarily since silica does not affect the optical properties of the nanoparticles due to its transparency.…”

Nanomedical systems have attracted considerable attention primarily due to suitability in applications for specific cell selection through biomolecular targeting and rare cell detection enhancement in a diverse, multicellular population. In the present study, magnetic nanoparticles were prepared for use in high accuracy cell sensing. Magnetic nanoparticle growth was assisted by mid-infrared lighting. By this mechanism, a narrow window, estimated to be 2%, was achieved for the dimension distribution of grown nanoparticles. Combined with silicon nanowire (SiNW) transistors, a sensor with ultra high sensitivity for the detection of specific potential low abundance biomarkers has been achieved, which has been specifically used to detect interleukin-6 (IL-6) at extremely low concentrations. A novel biosensor with high sensitivity has been fabricated and utilized in the detection of IL-6 at 75 fM to 50 pM. The system consists of an SiNW transistor and magnetic nanoparticles with even dimension distribution. The novel sensor system is suitable for quantifying IL-6 at low concentrations in protein samples.

“…Ong et al [10] investigated the synthesis of FeCo nanoparticles by pulsed laser depositing using a diffusion cloud chamber. Baker et al [11] and Binns et al [12,13] performed X-ray magnetic circular dichroism (XMCD) measurements on exposed and Co coated Fe clusters and noticed an increase in the spin moments and even a relative larger enhancement of the orbital moments in comparison with bulk Fe.…”
