Characterization of the HA‐SNAs system. a) Size and b) zeta(ζ)‐potential changes of the nanosystem during the preparation. c) FTIR spectra of the HA, sense DNA, and ^DNAHA. d) SEM images of HA‐SNAs at different magnification and the TEM images of (d(iv)) Au NPs, d(v)) SNAs, and d(vi)) HA‐SNAs. f) Photothermal images of SNAs, HA+SNAs, HA‐SNAs irradiated at 808 nm (1.5 W cm⁻²) for 14 min, respectively. g) Temperature profiles of SNAs, HA+SNAs, HA‐SNAs irradiated at 808 nm (1.5 W cm⁻²) for 14 min, respectively. h) Temperature profiles of HA‐SNAs irradiated at 808 nm for 14 min with power densities of 1.0 and 1.5 W cm⁻², respectively.
