    Abstract: Ein verbessertes Substrat zur Herstellung einer Leiterplatte (PCB) umfasst eine auf ein Glasfasersubstrat aufgebrachte hydrophobe Silanbeschichtung einer Silanzusammensetzung, die mit einem Silanhaftvermittler vermischt ist. Der Silanhaftvermittler wird auf die Oberfläche des Substrats aufgebracht, um das Substrat mit einer Lackbeschichtung zu verbinden. Durch das Aufbringen des Silanhaftvermittlers auf die Oberfläche des Substrats werden Oberflächensilanole erzeugt, welche in das Anwachsen von anodisch leitfähigen Fasern (CAF) verwickelt sind. Eine Silanzusammensetzung, welche mit den Oberflächensilanolen reagiert, wird auf die Oberfläche des Substrats aufgebracht, welches den darauf aufgebrachten Silanhaftvermittler aufweist, um die hydrophobe Silanbeschichtung zu bilden. Die Oberfläche, welche durch die hydrophobe Silanbeschichtung/das Substrat dargestellt wird, ist hydrophob und weitgehend Silanol-frei. Diese Oberfläche wird anschließend getrocknet, und es wird darauf Lack aufgetragen. Dann werden das Substrat, die hydrophobe Silanbeschichtung und der Lack Härtungsbedingungen ausgesetzt, um die PCB zu definieren.

    Abstract: A method of forming a sample assembly of a biological sample having target antigens comprises: forming at least one sample trench within an outer layer, the sample trench having a bottom surface; forming a base layer; bonding a first set of antibodies within the sample trench on a first surface of the base layer; exposing the sample trench with the first set of bonded antibodies to the biological sample having target antigens, the target antigens bonding with the first set of antibodies within the sample trench; bonding a second set of antibodies to nanoparticles, the first and second sets of antibodies being biologically identical; and exposing the target antigens within the sample trench to the second set of antibodies bonded to the nanoparticles, the second set of antibodies bonding with the target antigens within the sample trench.

    Abstract: An enhanced substrate for making a printed circuit board (PCB) includes a hydrophobic silane coating of a silane composition intermixed with a silane coupling agent applied to a glass fiber substrate. The silane coupling agent is applied to the surface of the substrate for coupling the substrate to a varnish coating. Applying the silane coupling agent to the surface of the substrate creates surface silanols, which are implicated in conductive anodic filament (CAF) growth. A silane composition, which reacts with the surface silanols, is applied to the surface of the substrate having the silane coupling agent applied thereto to form the hydrophobic silane coating. The surface presented by the hydrophobic silane coating/substrate is hydrophobic and essentially silanol-free. This surface is then dried, and varnish is applied thereto. Then, the substrate, hydrophobic silane coating and varnish are subjected to curing conditions to define the PCB.
