= 38.8 ± 2.8%), blue-green photoluminescence yield and low cytotoxicity. Photophysical properties were demonstrated by the photogeneration of Au nanostructures upon 300 nm light exposure, according to the calculated semiconductor band-gap value of 2.45 eV. In summary, the synthesized nanocomposite exhibits enhanced thermal responsiveness, robust photothermal properties, and high structural stability, making it a promising platform for targeted cancer therapy and precision drug delivery applications.
