基于纳米颗粒的诊断和治疗剂因其在临床肿瘤学和其他生物医学研究中的潜力而引起了人们的极大兴趣。 [1]多功能纳米结构已被证明可用于体内应用,例如用于药物输送的脂质和聚合物纳米胶囊、[2] 用于磁共振成像的氧化铁纳米颗粒、[3] 用于 X 射线计算机断层扫描的金纳米颗粒、[4] 以及用于荧光成像的量子点 (Qdot)。 [5] Qdot 代表了过去十年中转化为生物学的令人兴奋的纳米技术之一。尺寸可调的发光使它们作为生物标记、成像和传感的多色荧光团很有吸引力。 [6, 7] 然而,对于体内应用,Qdot 的内在毒性是一个至关重要的问题,[8] 这可能会阻碍其最终的临床转化。因此,使用生物良性材料设计明亮的探针对于许多体内临床应用来说是非常理想的。
Nanoparticle-based diagnostic and therapeutic agents have attracted considerable interest because of their potential for clinical oncology and other biomedical research.[1] Versatile nanostructures have been demonstrated for in vivo applications, such as lipid and polymeric nanocapsules for drug delivery,[2] iron oxide nanoparticles for magnetic resonance imaging,[3] gold nanoparticles for X-ray computed tomography,[4] and quantum dots (Qdots) for fluorescence imaging.[5] Qdots represent one of the exciting nanotechnologies translated to biology in the past decade. The size-tunable luminescence makes them appealing as multicolor fluorophores for biological labelling, imaging, and sensing.[6, 7] For in vivo applications, however, the intrinsic toxicity of Qdots is of critical concern,[8] which may impede their final clinical translation. Therefore, the design of bright probes with biologically benign materials is highly desirable for many in vivo clinical applications.
