Photothermal microfabrication system: (
A) Schematic of the new agarose microneedle etching system. (
B) Schematic of a conventional agarose direct etching system. (
C) In the new system, a platinum-coated microneedle is heated by the focused near-infrared laser to melt microchannels in the thin agarose layer. (
D) A phase-contrast image showing spot heating from light absorption at the tip of the 0.7 μm-diameter microneedle. Bar, 10 μm. (
E) A micrograph of four 200 μm-long microchannels with 6 (blue arrow), 7 (orange arrow), 8 (green arrow) and 9 mW (red arrow) near-infrared lasers. Bar, 50 μm. (
F) Microchannel widths—blue ([mean ± SD
