Digital (nano)colloid-enhanced Raman spectroscopy enables reproducible quantification of a wide range of target molecules at very low concentrations through single-molecule counting, overcoming the challenges of signal heterogeneity and poor reproducibility faced by conventional surface-enhanced Raman spectroscopy.

Research published in Nature shows that surface-enhanced Raman spectroscopy carried out with colloids can quantify a range of molecules down to concentrations at the femtomolar level.
