## Abstract The detection of underivatized anionic sulfonates, carboxylates, amino acids, sugars, and artificial sweeteners, and of cationic dopamine, ephedrine, and metanephrine in microfabricated electrophoresis devices is demonstrated. This was achieved by highβvoltage contactless conductivity m
Contactless conductivity measurements were found to be suitable for the direct detection, i.e., without needing any labels, of a range of biochemically relevant species, namely amino acids, peptides, proteins, immunoglobulin, and DNA. It was also possible to monitor the products of the enzymatic dig
