a Monitoring the photothermal heating of the BDS gel with a thermal imaging camera. b–e Photographs of the descending process of the BDS gel in a 10 mg/mL D-glucose solution and under irradiation of a sunlight simulator (hh:mm:ss:ms – t0 starts when the gel has finished ascending – the whole movie process is shown in Supplementary Fig. S10a). f Time-resolved glucose concentration of the solution during the irradiation. The red and blue areas represent the ascent (red) and descent (blue) of the BDS-gel. g Schematic representation of the temperature-dependent buoyancy behavior of the shuttle gels.
