基于金纳米颗粒 (AuNP) 的目标可激活荧光探针已被开发用于可视化体内蛋白水解活性,该探针由染料标记肽和聚乙二醇的自组装异质单层功能化。提出了一种一步合成策略,可以简单地生成表面定义的 AuNP 探针库,作为定制和评估探针特性的一种方法,以在蛋白酶激活后实现最大荧光增强。针对胰蛋白酶和尿激酶型纤溶酶原激活剂的最佳 AuNP 探针需要掺入暗猝灭剂才能实现 5 至 8 倍的信号放大。这些探针在小鼠肿瘤模型中表现出延长的体内循环时间和高图像对比度。
Target-activatable fluorogenic probes based on gold nanoparticles (AuNPs) functionalized with self-assembled heterogeneous monolayers of dye-labeled peptides and poly(ethylene glycol) have been developed to visualize proteolytic activity in vivo. A one-step synthesis strategy that allows simple generation of surface defined AuNP probe libraries is presented as a means of tailoring and evaluating probe characteristics for maximal fluorescence enhancement after protease activation. Optimal AuNP probes targeted to trypsin and urokinase-type plasminogen activator required the incorporation of a dark quencher to achieve 5 to 8-fold signal amplification. These probes exhibited extended circulation time in vivo and high image contrast in a mouse tumor model.
