Abstract
- A combination of an immuno-affinity enrichment strategy and sensitive amperometric read-out was implemented in a point-of-care platform intended for bacterial infection analysis. Bacterial cells, selectively captured and enriched from complex matrices through immuno-affinity, were detected by amperometric monitoring of the redox state of metabolic activity indicators, providing species identification and viable-cell quantification. The method was successfully employed for the diagnosis of bacterial infections including antimicrobial susceptibility testing with only several hours of total working time. Immunaffinitätsanreicherung und empfindliches amperometrisches Auslesen wurde in einer Point‐of‐Care‐Plattform zur Analyse bakterieller Infektionen kombiniert. Bakterielle Zellen wurden aus komplexen Matrices durch Immunaffinität selektiv eingefangen und angereichert und durch amperometrisches Untersuchen des Redoxzustands stoffwechselaktiver Indikatoren nachgewiesen. Die Identität der bakteriellen Spezies und die Zelllebensfähigkeit wurden so bestimmt. Die Methode wurde erfolgreich zur Diagnose bakterieller Infektionen verwendet, was die Untersuchung der Antibiotikasensibilität innerhalb von nur wenigen Stunden Gesamtarbeitszeit mit einschloss.
