Fig. 2. Characterization of LProd.

Fig. 2.

(A) The surface charge (Zeta potential) of LDNc, LDNc-PMI and LProd measured in PBS buffer (pH 7.4) by DLS at 37 °C. All data points were the average of 20 measurements and were fitted by to a Gaussian distribution. (B) FT-IR spectroscopy of LDNc, LDNc-PMI and LProd. (C) UV-vis absorption spectra of LDNc, LDNc-PMI and LProd. (D) Small angle X-ray scattering (SAXS) diffractograms of LProd measured at the concentration of 0.1 mg/mL in PBS. The orange line is the least squares fit to the data (green points) using a rod model. (E) Corresponding chord length distributions calculated from (D). P (r) = chord length distribution function; R = radius. (F) The schematic illustration of nanobacteria-like LProd size, which was obtained from (E). (G) TEM image of LProd taken at 100 kV. (H) SAXS diffractograms of 1 mg/mL LProd in PBS. The orange line is the least squares fit to the data (green points) using a sphere model. (I) Corresponding chord length distributions calculated from (H). (J) Internal morphology of LProd obtained from (I). (K) High-resolution TEM (HRTEM) image of LProd taken at 300 kV.
