CA 2460212

The invention provides efficient methods for rapidly and sensitively identifying cellular and viral targets in medical, industrial, and environmental samples. The invention labels targets and then detects them using large area imaging. Diagnostic tests based on the invention can be rapid, ultrasensitive, quantitative, multiplexed, and automated. The tests minimize sample preparation and do not require nucleic acid amplification or cell culture. A broad range of cells and viruses can be detected by the tests. Tests based on the invention can deliver the high level sensitivity of nucleic acid amplification tests, the user-friendliness, and speed of immunoassays, as well as the cost effectiveness and quantification offered by microbiological tests. The invention embodies the best attributes of the current diagnostic technologies, while addressing gaps in the diagnostic repertoire.

L'invention concerne des procédés efficaces destinés à identifier rapidement et avec sensibilité des cibles cellulaires et virales dans des échantillons médicaux, industriels et de l'environnement. L'invention permet de marquer des cibles et de les détecter au moyen d'une imagerie à grande plage. Les tests de diagnostic reposant sur l'invention peuvent être rapides, ultrasensibles, quantitatifs, multiplexés et automatisés. Les tests minimisent la préparation d'échantillon et ne nécessitent ni amplification d'acides nucléiques ni culture cellulaire. Il est possible à l'aide de ces tests de détecter un large domaine de cellules et de virus. Les tests reposant sur l'invention peuvent délivrer la sensibilité de niveau élevé des tests d'amplification d'acides nucléiques, la rapidité des tests immunologiques, être conviviaux pour l'utilisateur et présenter l'efficacité économique et la quantification offertes par les tests microbiologiques. L'invention met en valeur les meilleurs attributs des techniques de diagnostic actuelles tout en remédiant aux manques du répertoire de ces techniques.
