    Bruker Corporation d2 phaser x ray diffractometer
    Preparation and characteristics of Au-HA-functionalized SN38 NPs. (a) HA NPs are prepared by complexing SN38 with a human serum albumin (HSA)-based HA/PEI mixture. Simultaneously, Au NP-incorporated HA NPs (Au/HA NPs) are synthesized by integrating PEI-stabilized Au NPs into the HA/albumin complex. HA-functionalized SN38 NPs are prepared using a lyophilization–hydration method. (b) Transmission electron microscopy images of HA NPs and Au/HA NPs. Samples are negatively stained with 2 % uranyl acetate before imaging. Scale bar = 200 nm. (c) The average size and zeta potential of HA NPs and Au/HA NPs are analyzed using dynamic light scattering and aqueous electrophoresis. Each experimental group includes five samples ( n = 5). Data are expressed as the mean ± standard error of the mean. Statistical analyses are performed using the Mann–Whitney U test. (d) Full scan XPS spectrum of HA NPs and Au/HA NPs. <t>(e)</t> <t>X-ray</t> diffraction patterns of SN38, HA NP, and Au/HA NPs. (f) Storage stability of NPs as evaluated according to particle size (D) is determined by dissolving the re-lyophilized HA NPs and Au/HA NPs in 1 mL double-distilled water (ddH 2 O). Each experimental group include five samples ( n = 5). (g) Colloidal stability of NPs, as measured according to particle size (D), is assessed in Dulbecco's Modified Eagle Medium (Gibco) supplemented with 10 % ( v /v) fetal bovine serum to evaluate stability under physiologically relevant conditions. Each experimental group includes five samples (n = 5). (h) Representative and (i) quantitative cell surface CD44 expression posttreatment with SN38, HA NPs, and Au/HA NPs in A549, H226, and LLC cells as determined using flow cytometry. Each experimental group includes five samples (n = 5). Data are expressed as the mean ± standard error of the mean. Statistical significance is assessed using the one-way analysis of variance with Tukey's multiple comparisons test. * P < 0.05; ** P < 0.01; *** P < 0.001.
