Abstract: Disclosed are miniaturized electronic systems, devices and methods for biomarker analysis, which can be incorporated into blood collection tubes and other containers that enable the immediate isolation, concentration, analysis and storage of disease related biomarkers upon blood draw. In some aspects, a miniaturized electronic system includes a high-surface area folded or sandwiched electrokinetic microelectrode array chip device that allows both AC dielectrophoretic (DEP) and DC electrophoretic based separation and isolation and other processes to be used for the concentration and biomarkers.

Abstract: Three-dimensional boron particle loaded thermal neutron detectors utilize neutron sensitive conversion materials in the form of nano-powders and micro-sized particles, as opposed to thin films, suspensions, paraffin, etc. More specifically, methods to infiltrate, intersperse and embed the neutron nano-powders to form two-dimensional and/or three-dimensional charge sensitive platforms are specified. The use of nano-powders enables conformal contact with the entire charge-collecting structure regardless of its shape or configuration.

Abstract: Methods for manufacturing solid-state thermal neutron detectors with simultaneous high thermal neutron detection efficiency (>50%) and neutron to gamma discrimination (>104) are provided. A structure is provided that includes a p+ region on a first side of an intrinsic region and an n+ region on a second side of the intrinsic region. The thickness of the intrinsic region is minimized to achieve a desired gamma discrimination factor of at least 1.0E+04. Material is removed from one of the p+ region or the n+ region and into the intrinsic layer to produce pillars with open space between each pillar. The open space is filed with a neutron sensitive material. An electrode is placed in contact with the pillars and another electrode is placed in contact with the side that is opposite of the intrinsic layer with respect to the first electrode.
