Abstract:
A photochrome-aptamer switch assay (PHASA) and biosensing device, based on it, that allows detection and quantification of analytes within minutes and removes laborious purification and washing protocols that limit some bioassays to several hours of incubation. The PHASA device comprises a single synthetic aptamer for sensing a single analyte of interest or alternatively, a series of different aptamers for sensing different preselected analytes. The aptamer is immobilised onto the surface of the device for the rapid assay of the analyte. The switchable reporter element of the PHASA device is any sensitive photochrome or fluorochrome probe, such as stilbene or diazo derivative chemically modified with the "pseudo- hapten" moiety connected to one end of the molecule. The pseudo-hapten mimics an active part of the preselected ligand or analyte, which creates strong interactions with the active site of the aptamer. The PHASA device does not rely on fluorescence intensity quantification or on fluorescence quenching. Rather, a unique feature of the switchable reporter molecule is their reporting power via an instant conformational change upon irradiation with the excitation light. This makes it unique in the sense that most fluorescent labels or probes either do not possess this intramolecular switchable nature or require the separation of adjacent fluorophores.
