a, Optical image of a representative multi-sample ferrobotic platform for individual testing (here, 32 test sites). b, Exploded schematic of the microfluidic layer and actuation/sensing layer for a ferrobotic viral testing device designed for individual testing. c, Programmed input current profiles of two neighboring (12-mm apart) on-board resistive heaters and the correspondingly established local temperature profiles. d, Characterization of optical sensor readout versus standard Nanodrop readout (using solutions containing different concentrations of a pink color dye. Error bars, mean values ± SE (n = 5 independent optical sensor readouts). e, Schematic diagram of the circuitry for a multi-sample individual testing PCB (extended into an array format). f, Schematic diagram of the control circuitry used for multiplexed testing (featuring an expanded coiled navigation floor).
