Aptamer based dispersion assay using tunable resistive pulse sensing (TRPS) by Emily R. Billinge, Mark Platt

“…The technique allowed the detection of thrombin down to sub picomolar concentrations, and an increase in sensitivity over previous assays on the same platform. The sensitivity of the assay is attributed to each thrombin protein disrupting multiple aggregates resulting in a signal amplification.…”

Tuning colourimetric indicator displacement assays for naked-eye sensing of pyrophosphate in aqueous media by Xuejian Liu, Huy Tien Ngo, Zijun Ge, Stephen Butler, Katrina A. Jolliffe

“…A library of anion receptors comprising cyclic peptide scaffolds bearing two (ZnII-DPA) anion binding sites have been synthesised and their anion binding abilities evaluated using colourimetric indicator displacement assays with three different indicators. The resulting chemosensing ensembles provided excellent discrimination between polyphosphate ions, with several of the receptor:indicator combinations providing naked-eye sensing of pyrophosphate ions in aqueous solutions containing more than 100 fold excess of ATP.…”

A continuous luminescence assay for monitoring kinase activity: signalling the ADP/ATP ratio using a discrete europium complex by Sarah Hewitt, Jonathan Parris, Romain Mailhot, Stephen Butler

“…We report the application of a stable cationic europium complex [Eu.1]+ in a continuous-read luminescence assay for kinase activity. [Eu.1]+ binds reversibly to ATP and ADP in water, at neutral pH, in the presence of Mg2+ ions, providing distinctive luminescence responses that permits the kinase-catalysed conversion of ATP to ADP to be monitored in real-time.…”
