title: Sensitive detection of protein by an aptamer-based label-free fluorescing molecular switch.
abstract: We report an aptamer-based method for the sensitive detection of proteins by a label-free fluorescing molecular switch (ethidium bromide), which shows promising potential in making protein assay simple and economical.
