Abstract: A type of microfluidic platform, photothermal bar-chart chip (PT-Chip), uses on-chip nanomaterial-mediated photothermal effect as a tunable microfluidic driving force to drive ink bar-charts in a visual quantitative readout fashion. The photothermal bar-chart pumping performance can be adjusted remotely by tuning the irradiation parameters, without the need to change any on-chip parameters. The PT-Chip enables a POC visual quantitative diagnostics, by forming nanomaterial-mediated photothermal effects-driven bar-chart microchip for visual quantitative immuno-sensing. In this immunoassay, biomolecules are visually quantified by directly reading the distance that fluids move on the PT-Chip.
