Abstract Some of the challenges with detection of ultra-low concentrations of analytes are to achieve sufficient sensitivity of the measurement and to direct the analyte species to the sensor (electrode) surface. This review describes various strategies that are available to address these challenges: method of electrocatalytic amplification, electrochemical measurements performed in combination with electrokinetic preconcentration of analytes, ultra-sensitive analysis utilizing increased surface area and also the manipulation by the magnetic force.
