Biosensor comprising an activatable acceptor fluorogen linked via a linker to a donor which transfers energy to the fluorogen on detecting an analyte wherein the fluorogen component reacts and a 100 fold increase in intensity results when the fluorogen interacts non-covalently with an activator e.g. fluorogen activator peptide.
