(a) Schematic illustration of the preparation of AADF via a facile one-step synthetic method. (b) Cryo-TEM micrographs of AADF. Scale bar is 200 nm. (c) Hydrodynamic size distributions of AADF in aqueous solution. (d) Comparison of Z-average sizes and the zeta potentials of AADF. (e) X-band EPR spectra of the hydroxyl radicals captured by DMPO after treatment with 100 μg/mL C70-Ala and C70-Lys. Ultrapure water was used as a blank. (f) Scavenging efficiency with the concentration increase of AADF measured by EPR.
