A highly selective optical biosensor based on ligand-induced folding. The sensor is sufficiently selective that we can detect its target peptide even in blood serum, a realistically complex and contaminant-ridden clinical material. Shown are background-subtracted fluorescence spectra of 1 μM sensor in 50% FCS and in serum doped with 8 mM target peptide.
