Patent number: 7846396Abstract: A droplet sample holder, especially a sample holder for use in a measuring instrument utilizing surface plasmon resonance. The sample holder reduces or minimizes the measurement distortion result of the droplet “pherpheral concentration effect” by surrounding the analysis zone with a wettable (hydrophilic) zone that captures the periphery of the droplet to keep the pheriphery of the droplet and the increased concentration of the analyte out of the analysis zone. The wettable zone is surrounded by a nonwettable (hydrophobic) zone that restricts the periphery of the droplet to analysis zone and the wettable zone.Type: GrantFiled: May 31, 2005Date of Patent: December 7, 2010Assignee: Sierra Sensors GmbHInventors: Daniel B.
