摘要
(Graph Presented) Layered enzyme assays: The use of a layered sol-gel based material allows for spatial separation of coimmobilized enzyme and fluorescent aptamer reporter species. This provides a route for facile assaying of enzyme activity and inhibition in cases where the aptamer signals the presence of the enzyme substrate. This then results in accurate IC50 determinations. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
