Homogeneous Protein Analysis by Magnetic Core–Shell Nanorod Probes

Homogeneous Protein Analysis by Magnetic Core-Shell Nanorod Probes.

Studying protein interactions is of vital importance both to fundamental biology research and to medical applications. Here, we report on the experimental proof of a universally applicable label-free homogeneous platform for rapid protein analysis. It is based on optically detecting changes in the rotational dynamics of magnetically agitated core-shell nanorods upon their specific interaction w...

Separation and Recovery of Platinum by Magnetic Coreshell Nanostructures Modified with N-(2-aminoethyl)-3- aminopropyltrimethoxysilane

In this paper, Fe3 O4 @SiO2 core/shell magnetic nanostructure has been synthesized and modified by N-(2-aminoethyl)-3-aminopropyltrimethoxysilane (AEAPTMS). Fe3 O4 @SiO2 was used as a novel adsorbent for separation of hexachloroplatinic acid. X-ray diffraction (XRD), scanning electron microscopy (SEM), and FT-IR technique were used to characterize morphologies and surface texturing of these ads...

Magnetic force microscopy using fabricated cobalt-coated carbon nanotubes probes

Magnetic force microscope ( MFM ) is a powerful technique for mapping the magnetic force gradient above the sample surface. Herein, single-wall carbon nanotubes (SWCNT) were used to fabricate MFM probe by dielectrophoresis method which is a reproducible and cost-effective technique. The effect of induced voltage on the deposition manner of carbon nanotubes (CNT) on the atomic force microscope (...

Gold nanorod probes for the detection of multiple pathogens.

Identity profiling of cell surface markers by multiplex gold nanorod probes.

Gold nanorod molecular probes (GNrMPs) were designed and fabricated for multiplex identification of cell surface markers in HBECs. Cells were probed directly using dark field microscopy integrated with a spectral imager for simultaneous detection of up to three surface markers. The immunophenotype composition of these cell lines indicative of their metastasis potential was assessed using the GN...
