Label-free protein quantitation by dielectric spectroscopy of dual-frequency liquid crystal

•A novel method based on dual-frequency liquid crystal (DFLC) is developed for label-free protein assay.•The unique dielectric nature of DFLC is the key of the mechanism.•The frequency-dependent dielectric properties resolve the problem caused by cell-gap variations.•Dielectric analysis permits unam...
