Abstract: The invention provides immunochromatographic test strips and methods for detecting and quantifying S-Adenosylmethionine (SAM), S-Adenosylhomocysteine (SAH) and Homocysteine (HCy) in a sample, comprising: (a) making fluorophore conjugated antibodies; (b) immobilizing SAM, SAH and HCy on a solid support; (c) providing a sample, combining said sample with a conjugate selected from the group consisting of lanthanide chelate conjugates and quantum dot conjugates (QD) with anti-SAM, anti-SAH or anti-HCy, wherein said combining is performed under conditions that allow formation of a competitive complex comprising said conjugate, said SAM, SAH or HCy on the solid support and SAM, SAH or HCy in a sample when present; and (d) detecting the presence of the complex, if present, by monitoring a spectral emission mediated by the fluorescent conjugates in the complex, wherein the emission indicates the presence and quantity of SAM, SAH or HCy in the sample.

Abstract: Elastomeric fluoropolyether lubricant topcoats are formed on a protective overcoat of a magnetic recording medium. Embodiments include forming a an amorphous carbon layer having a thickness of no greater than about 25 ? as the protective overcoat and polymerizing a fluorpolyether having one or more acrylate groups on the amorphous carbon layer to form the elastomeric fluoropolyether topcoat lubricant directly on the protective overcoat.

Abstract: A high areal recording density, perpendicular magnetic recording medium, comprises: (a) a non-magnetic substrate having a surface with a layer stack formed thereon, the layer stack comprising, in overlying sequence from the substrate surface: (b) a soft ferromagnetic “keeper” or underlayer; (c) an anti-ferromagnetic coupling layer structure; and (d) a hard ferromagnetic perpendicular recording layer including a multilayer magnetic superlattice structure; wherein layers (b), (c), and (d) in stacked combination provide the medium with improved thermal stability and a high perpendicular coercivity which can exceed about 6,500 Oe.

Abstract: Reactive monomers of cyanate esters are vapor deposited onto thin film disks used for magnetic recording. The monomer films are then irradiated with ultraviolet (UV) light to polymerize the deposited monomer to form a solid, robust polycyanate ester overlayer on the disk that becomes smoother, more corrosion resistant and, when lubricated, more durable than disks without the overlayer. The polycyanate ester overlayer can either replace the conventional carbon overcoat or allow a substantially thinner carbon overcoat to be used.
