Fluorescence-based oligonucleotide probes, also known as molecular beacons (MBs), are popular for detecting nucleic acids with high specificity. Here, the authors demonstrate self-sequestration of MB-based biosensors and target strands within peptide-based coacervates, increasing local concentrations and significantly increasing the sensitivity and kinetics of the DNA biosensors.
