Beschreibung
Zusammenfassung:	A hand-held or portable SPR device focuses light at two or more positions on a noble metal sensor surface, functionalized to enable detection of different SPR curves and their respective minima. The detection is accomplished substantially simultaneously by obtaining SPR signals contemporaneously from the different locations on the sensor surface, on the same sensor. The SPR device may incorporate multiple light sources or a single light source with a beam that is shifted by deflectors in seriatim to focus on different positions on along the functionalized sensor surface. To control wettability of the sensor surface (to augment multiplexing), the sensor surface may include i) the addition of surface assembled monolayers (SAMs) and ii) surface bombardment by gaseous plasmas, most notably O2.
