Abstract: An allergen detection device that includes a sensor comprising a circuit board, an electropolymerized molecularly imprinted polymer film (MIP) that includes receptor sites imprinted in a first surface of the polymer, the receptor sites configured to accept a trace molecule of an allergen, and an electropolymerized non-imprinted polymer film. The sensor is configured to detect the presence of the trace molecule upon binding to one or more of the receptor sites on the MIP.

Abstract: Embodiments herein are directed to semiconductor package assemblies and methods of forming. In some embodiments, a semiconductor package assembly includes a substrate, a first metallization layer disposed adjacent the substrate, and a semiconductor die disposed in thermal contact with the first metallization layer. The semiconductor package assembly may further include a die attach layer disposed between the semiconductor die and the first metallization layer, the die attach layer including a polymer matrix and a nano-metal particle filler.

Abstract: There are described compositions and methods for the laser marking of products or their packaging. The compositions comprise transition metal oxides, saccharides and/or flame-retardant agents, optionally with other additives, dispersed in a carrier.

Abstract: A laser-markable composition comprises a binder and an oxyanion of a multivalent metal.

Abstract: An apparatus for positioning a graft and catheter operable for subcutaneous access to the vascular system of a patient. A surgically created, hybrid arteriovenous shunt is provided which comprises a flexible graft and a venous outflow catheter connected to the graft via surgical anastomosis over a cuff. The graft is connected to an arterial source and then to a single lumen venous outflow catheter which deposits dialyzed blood directly into the heart at the right atrium. Methods of surgical placement and performing hemodialysis using embodiments of the apparatus are provided.

Abstract: Laser-markable compositions and methods for providing an image on a substrate are provided. A laser-markable composition can include a pigment, a solvent, and a conductive polymer that absorbs IR radiation. This can be used to mark a substrate, using a low-energy laser. Irradiation can be by means of a near-IR laser source, and the conductive polymer can absorb radiation and transfer heat to the pigment.
