A biosensor may provide a magnetoresistive (MR) film comprising a nonmagnetic layer may be sandwiched between the two ferromagnetic layers. The MR film may be positioned on a substrate, where the edges of the MR film are in contact with leads. Additionally, the leads may be in contact with pads. The sensors may provide quasi-digital readout that enable greatly enhanced sensitivity. In some embodiments, biosensors may be arranged as array of sensors. The array of sensors may be arranged as a symmetric or asymmetric N&#xd7;Narray, where Nand Nare integers, Nrepresents the number of sensors linked together in series, and Nrepresents the number of sensor sets in parallel, where each sensor set may comprise one or more sensors. Further, the array of sensors may be coupled to a voltmeter, which may be a single voltmeter in some cases that allows the sensors to all be probed simultaneously.

Biosensor for detecting a single magnetic label

The invention is a novel and non-obvious design and implementation of an inductive sensor for quantifying magnetic particles. The invention parts way from the conventional methods of using wounded coils to a design that is compatible with an integrated circuit (IC) chip fabrication processes and/or printed circuit board (PCB) manufacturing. The increased accuracy from these fabrication methods provides a significant improvement to sensor sensitivity. In addition, the design of the inductive sensor enables easy integration with lateral flow assay (LFA) technology. The sensor can be applied to detect and quantify molecules to provide information on health, hazard or safety.

Ultra-sensitive volumetric magnetic particle detector

In the systems and methods for synthesizing a thin film with desired properties (e.g. magnetic, conductivity, photocatalyst, etc.), a metal oxide film may be deposited on a substrate. The metal oxide film may be achieved utilizing any suitable method. A reducing agent may be deposited before, after or both before and after the metal oxide layer. Oxygen may be removed or liberated from the deposited metal oxide film by low temperature local or global annealing. As a result of the annealing to remove oxygen, one or more portions of the metal oxide may be transformed into materials with desired properties. As a nonlimiting example, a metal oxide film may be treated to provide a magnetic multilayer film that is suitable for bit patterned media.

Systems and methods for locally reducing oxides

Embodiments of the present disclosure provide a method for selective removal of atoms from a substrate. Such a method comprises forming a patterned mask over at least a portion of the surface of the substrate to form a masked portion and an unmasked portion of the surface. In an embodiment, the method comprises exposing the surface to low energy light ions. In a related embodiment the low energy light ions selectively remove atoms from the unmasked portion of the substrate. In some embodiments, the method further comprises removing the mask. In another embodiment, the present disclosure relates to a method of creating a plurality of magnetic domains on a magnetically susceptible substrate. In an embodiment, the present disclosure pertains to a method of forming a magnetic medium.

System and method for selectively removing atoms and uses thereof

An auto loading and auto dampening cleaning apparatus which comprises a base sweeping pad, a fluid reservoir superimposed over said sweeping pad which defines a slit between the two, a handle having a fork shaped frame which is rotateably attached to the sweeping pad. A lower roll bar contains clean, cleaning material and an upper roll bar receives soiled cleaning material. First and second trigger mechanism activates the roll bars and fluid reservoir to advance the cleaning material and disperse cleaning solution onto the cleaning material on the lower roll bar passes through the slit defined by the fluid reservoir and sweeping pad around the bottom of the sweeping pad and up to the upper roll bar.

Auto loading and auto dampening cleaning apparatus

A die board assembly includes a support plate providing a plurality of through holes arranged along lines of an X-Y grid pattern. The support plate further provides a plurality of shaped apertures positioned within the support plate to a selected depth. One of the apertures is positioned between each pair of the through holes, the apertures providing aperture legs coincident with the lines of the X-Y grid. A plurality of rigid cylindrical receivers are adapted for engagement within one of the through holes and a plurality of resilient bumpers, are engaged within the cylindrical receivers for support thereof, each of the bumpers being segmented into a plurality of segments with segment spaces in separation thereof. A plurality of elongate blades each provide a working edge and in opposition thereto, an engagement edge, the engagement edge configured so as to engage a plurality of the shaped apertures and at least one of the resilient bumpers such that a terminal surface of the bumpers extends beyond the working edge of the blades relative to the support plate. Each elongate blade engages at least one of the segment spaces between the resilient bumper segments in support of the blade.
