We report on specific magneto-capturing followed by Multidimensional Protein Identification Technology (MudPIT) for the analysis of surface-exposed proteins of intact cells of the bacterial opportunistic pathogen Pseudomonas aeruginosa. The magneto-separation of cell envelope fragments from the soluble cytoplasmic fraction allowed the MudPIT identification of the captured and neighboring protei...

We present a theoretical and experimental study on the biosensing sensitivity of Au/Co/Au multilayers as transducers of the magneto-optic surface-plasmon-resonance (MOSPR) sensor. We demonstrate that the sensing response of these magneto-plasmonic (MP) transducers is a trade-off between the optical absorption and the magneto-optical activity, observing that the MP multilayer with larger MO effe...

Diluted magnetic semiconductors (DMSs) are semiconductors alloyed with magnetic elements [1]. The physical properties of these materials can be tuned by both charge and spin, thus, they have great potential of being used in a wide variety of spintronic applications, such as magneto-optical, magneto-electrical, and magneto-transport devices. Spintronics (spin+electronics) is the technology that ...

Magneto-Optical Spectroscopy of (III,Mn)V Ferromagnetic Semiconductors

Iron-filled magnetorheological polymers, when cured in the presence of a magnetic field, result in having a transversely isotropic structure with iron particles forming chains along the direction of applied magnetic induction. In this work, we model the magneto-viscoelastic deformation (and magnetization) process of such polymers. Components of the deformation gradient and the applied magnetic ...

Background & Aims: Antibodies, well-known as immunoglobulins (Igs), are produced by B lymphocytes and specifically defend against pathogens. Igs are glycoproteins and have high diagnostic value in several diseases including infections (1). Igs are composed of light and heavy chains (2, 3). Each chain is comprised of about 110-120 amino acid residues which create immunoglobulin folds named domai...

We report on a series of measurements on the microscopic structure and the magneto-optical properties of a calamitic liquid crystalline compound in its nematic phase. Structural studies show the existence of short-range, tilted smectic order consistent with pretransitional effects above an underlying smectic phase. Concomitantly, magneto-optical results exhibit the existence of an optic axis no...
