a Optical transmittance at 650 nm for five cycles between the SMEH-CS and ASP-CS dissipative processes over time. The blue parts represent the light-induced formation of ASP-CS, and the gray parts represent the dissociation process. b The energy changes over the dissipative assembly process. c Decrease in absorbance of SMEH-CS at 424 nm upon 420 nm irradiation over time at different irradiation power densities from 5 to 25 mW/cm2. d Variation in absorbance at 424 nm and optical transmittance at 650 nm during the thermal dissociation process of ASP-CS over time at different temperatures. e Partial confocal images of SMEH-CS-C153 in aqueous solution over time showing reversible formation/dissociation of fluorophore-loaded nanoparticles, including two cycles (the first cycle is on the top line, and the second cycle is on the bottom line; scale bar = 5 μm). f Total number of fluorescent particles detected by confocal microscopy over time (measured every 20 s for the formation process and every 5 min for the dissociation process). ([SMEH]initial = 0.15 mM, [CS] = 40 μg/mL, [C153] = 0.001 mM, λex = 405 nm, λem = 480–520 nm, temperature: 25 °C, optical power density: 15 mW/cm2 unless mentioned).
