摘要:
A method of bonding an antimicrobial cationic polyelectrolyte to the surface of a substrate is described, wherein the antimicrobial thus attached to the substrate provides the substrate with antimicrobial properties, and at least a portion of the bonded antimicrobial is substantially non-leachable during normal conditions of use and storage. A method of manufacturing an antimicrobial material is described which comprises exposure of the substrate to a solution of antimicrobial cationic polyelectrolyte, followed by drying the exposed substrate thoroughly to impart a non-leaching property to at least a portion of the antimicrobial cationic polyelectrolytes.
摘要:
A reduced ground spring probe array and a method for controlling the impedance of the signal spring probes in the reduced ground spring probe array. Signal spring probes are positioned in a row-column format across the surface of the spring probe tower. Ground spring probes are positioned in a row/alternating-column format across the surface of the spring probe tower such that one ground probe is positioned between two or more signal probes. In doing so, a void space exists for every other ground probe column such that one or more signal lines may be routed within the void space or the array may be compressed to establish a smaller overall spring probe tower footprint.

A multiwell plate device is provided having a frame, a substantially flat substrate and a multiwell structure supported by the substrate. The multiwell structure includes multiple bottomless wells formed therein. The substrate is supported by the frame and may be processed by an automated arrayer or instrument that is used to print or spot arrays in a pattern on a reaction surface of the substrate. Thereafter, the multiwell structure may be engaged with the substrate and the multiwell structure and substrate may be engaged with the frame in an upright orientation. For scanning or other analysis, the multiwell structure and substrate may be disengaged from the frame, inverted 180°, and then reengaged with the frame in the inverted orientation.
