"诊疗一体化"多功能探针可在准确了解病变位置和类型的同时实施治疗,有望在实现疗效最大化的同时将不必要的毒副作用减少到最低[1].具有良好生物亲和性和易修饰性的金纳米材料为发展"诊疗一体化"探针提供了一种理想的基体材料.一方面,其可直接作为示踪剂用于暗场等成像研究,或与荧光等其他信号元件整合而被赋予多模式信号[2];另一方面,其自身即可作为有效光吸收剂进行光热转换用于光热治疗[3].

手性药物在体内的药理活性、代谢过程及毒性存在着显著差异[1].因此,手性表征及识别在生命过程中极其重要.本文利用室温磷光光谱法以及时间分辨磷光光谱法实现了对氧氟沙星对映体的手性识别,同时,借助分子模拟等方法[2]进一步对分子手性识别机理进行了探讨.
