説明
<jats:title>Abstract</jats:title><jats:p>Fluorescent gold nanoclusters (AuNCs) capped with lysozymes are used to deliver the anticancer drug doxorubicin to cancer and noncancer cells. Doxorubicin‐loaded AuNCs cause the highly selective and efficient killing (90 %) of breast cancer cells (MCF7) (IC<jats:sub>50</jats:sub>=155 n<jats:sc>m</jats:sc>). In contrast, the killing of the noncancer breast cells (MCF10A) by doxorubicin‐loaded AuNCs is only 40 % (IC<jats:sub>50</jats:sub>=4500 n<jats:sc>m</jats:sc>). By using a confocal microscope, the fluorescence spectrum and decay of the AuNCs were recorded inside the cell. The fluorescence maxima (at ≈490–515 nm) and lifetime (≈2 ns), of the AuNCs inside the cells correspond to Au<jats:sub>10–13</jats:sub>. The intracellular release of doxorubicin from AuNCs is monitored by Förster resonance energy transfer (FRET) imaging.</jats:p>
