Abstract
Description
- - für die Auslesung sind sehr empfindliche Detektoranordnungen erforderlich, die zudem Anregungs- und Fluoreszenzlicht streng voneinander trennen müssen,
- - die Quantifizierung ist problematisch, da die Quantenausbeuten der Fluoreszenz sehr stark umgebungsabhängig sind (Tanke, H. J.; Herman B. Fluorescence Microscopy, Springer Verlag (1998)). Deshalb sind quantitative analytische Aussagen oft gar nicht oder nur mit einem sehr hohen Meßaufwand erreichbar (Rost FWD Quantitative Fluorescence Microscopy, Cambridge University Press. (1991), so daß beispielsweise eine Auswertung nur unter Einbeziehung von Messungen an mehreren Chips möglich wird (Hacia, J. G.; Brody, L. C.; Chee, M. S., Fodor, S. C.; Detection of heterozygous mutations in BRCA1 using high density olionucleotide arrays and two colour fluorescence analysis, Nature Genetics 14, 441-447 (1996)). Häufig scheitert jedoch selbst ein qualitativer Nachweis.
- 1. Eine einfache Handhabung des Affinitätssensors ist gewährleistet, da keine giftigen, cancerogenen und umweltschädlichen Farbstoffe zur Markierung zum Einsatz gelangen.
- 2. Es ist eine Unabhängigkeit des Signals von der chemischen Umgebung gegeben, weshalb der Affinitätssensor für quantitative Messungen verwendet werden kann.
- 3. Es erfolgen keine stofflichen Veränderungen (Ausbleichen o. ä.) während der Messung. Deshalb kann sogar bei einer scannenden Auslesung des aktiven Flächenbereichs 22 das ganze Assay beleuchtet bleiben, ohne daß Veränderungen in den Meßsignalen eintreten.
- 4. Kurze Inkubationszeiten sind gewährleistet, da selbst für eine hohe Anzahl einzelner Bindungsflächen der aktive Flächenbereich sehr klein festlegbar ist.
- 5. Durch den vorgeschlagenen Aufbau des Affinitätssensors ist ein günstiges Signal-Rausch-Verhältniss gegeben, wodurch kurze Meßzeiten realisierbar sind.
- 6. Durch die Möglichkeit der Ausbildung einer hohen Anzahl einzelner Bindeflächen auf einer sehr kleinen aktiven Fläche 22 ist die Auslesung mittels einfacher mikroskopischer Apparaturen gegeben. Im Gegensatz zum Stand der Technik sind keine Fluoreszenzoptiken und keine großen Objektive erforderlich.
- 7. Die Affinitätssensoren, die mit den Nanopartikelbelegungen versehen sind weisen eine langfristige Lagerstabilität auf, da die Partikelbelegungen von sich aus keinerlei Veränderungen erfahren, wodurch ihre Archivierung ermöglicht wird, was in der Medizin, insbesondere Gerichtsmedizin, der Umwelttechnik, der Prozeßkontrolltechnik und der Forschung neue Möglichkeiten eröffnet.
- 8. Durch die Quantifizierbarkeit und Lagerstabilität der Affinitätssensoren ist die Möglichkeit des Aufbaus von Kalibrier- oder sogar Eichnormalen gegeben.
Claims (13)
- - einem Objektiv eines üblichen lichtoptischen Mikroskops mit einer numerischen Apertur zwischen 0,1 bis 0,9, zwecks Bestimmung der durch die Nanopartikelbelegungen (31) erzeugten optischen Absorption, Reflexion oder Streuung oder
- - durch eine Vorrichtung zur Bestimmung der Plasmonenresonanz erfaßbar sind.
