具有特异性受体配体的纳米颗粒的功能化使得它们能够在靶向组织中积累,并且可以在治疗上用于运输药物或用于诊断目的(Parveen等人,Nanomedicine 8:147-166,2012)。我们最近可以表明,即使在生理条件下,使用量子点作为用整合素结合肽功能化的模型纳米颗粒,也可以实现靶向视网膜和脉络膜毛细血管中的内皮细胞(Pollinger et al.,Proc Natl Acad Sci 110:6115-6120,2013)。尽管我们使用的化学方法在文献中有很好的描述,并且可能被认为是用于该目的的标准方法,但仍有许多制备步骤是微妙的,值得特别注意。因此,我们打算逐步描述量子点表面上的配体固定的关键方法,以方便读者重现我们的工作。在这里,我们描述了用c(RGDfC)作为靶向肽的量子点的化学修饰,其允许所得到的修饰的纳米颗粒粘附到视网膜组织中的内皮细胞。我们通过展示我们以前研究的一些体外结果来说明所得颗粒的性质。这样做,我们同时鼓励读者首先通过流式细胞术和共聚焦显微镜对颗粒与细胞的相互作用进行广泛的体外分析来检查预期用于体内靶向细胞的颗粒,以确认成功的功能化。只有这样,将功能化量子点应用到小鼠的体循环中才导致纳米颗粒在视网膜和脉络膜血管中的期望定位(Pollinger等人,Proc Natl Acad Sci 110:6115-6120,2013)。
The functionalization of nanoparticles with specific receptor ligands enables their accumulation in targeted tissues and can be used therapeutically to transport drugs or for diagnostic purposes (Parveen et al., Nanomedicine 8:147–166, 2012). We could recently show that targeting endothelial cells in retinal and choroidal capillaries can be realized even under physiological conditions using quantum dots as model nanoparticles functionalized with an integrin-binding peptide (Pollinger et al., Proc Natl Acad Sci 110:6115–6120, 2013). Even though the chemistry that we used was well described in the literature and may be considered standard for the purpose, there are a number of preparation steps that are delicate and deserve special attention. It is, therefore, our intention to describe step by step the critical methods of ligand immobilization on quantum dot surfaces to facilitate the reader to reproduce our work. Here we describe the chemical modification of quantum dots with c(RGDfC) as targeting peptide that allows the resulting modified nanoparticles to adhere to endothelial cells also in the retinal tissue. We illustrate the properties of the resulting particles by showing some of the in vitro results from our previous studies. Doing so, we concomitantly encourage the reader to check particles intended for targeting cells in vivo first by extensive in vitro analysis of particle interaction with cells by the means of flow cytometry and confocal microscopy to confirm the successful functionalization. Only then the application of functionalized quantum dots into the systemic circulation of mice led to the desired localization of nanoparticles in the retinal and choroidal blood vessels (Pollinger et al., Proc Natl Acad Sci 110:6115–6120, 2013).
