近年来,医用纳米颗粒的开发在药物传递纳米制剂设计领域中占据了中心地位。医用纳米颗粒结合了治疗性递送系统(脂质体、胶束、纳米乳剂等)。使用成像试剂(MRI、光学、PET、CT)。这种结合允许对疾病器官和组织中的治疗性纳米颗粒进行非侵入性体内监测。在这里,我们报告了一种新型的全氟聚醚(PFPE)纳米乳液,其中含有一种不溶于水的亲脂性药物。该配方能够使用19F核磁共振成像和近红外(NIR)光学成像两种成像方式对纳米乳剂的生物分布进行非侵入性监测。该纳米乳液由作为19F磁共振示踪剂的PFPE-酪胺、碳氢油、表面活性剂和近红外染料组成。制备采用自组装和高能乳化相结合的方法,得到平均直径180 nm和低多分散指数(PDI小于0.2)的液滴。模型非类固醇抗炎药(NSAID)塞来昔布以0.2 mg/mL的浓度加入到处方中。已报道的纳米乳液的性质,包括小颗粒尺寸,在19F核磁共振和近红外荧光光谱下的可见性,以及携带药物的能力,使其成为一种有吸引力的潜在癌症成像和治疗药物。
Theranostic nanoparticle development recently took center stage in the field of drug delivery nanoreagent design. Theranostic nanoparticles combine therapeutic delivery systems (liposomes, micelles, nanoemulsions, etc.) with imaging reagents (MRI, optical, PET, CT). This combination allows for non-invasive in vivo monitoring of therapeutic nanoparticles in diseased organs and tissues. Here, we report a novel perfluoropolyether (PFPE) nanoemulsion with a water-insoluble lipophilic drug. The formulation enables non-invasive monitoring of nanoemulsion biodistribution using two imaging modalities, 19F MRI and near-infrared (NIR) optical imaging. The nanoemulsion is composed of PFPE-tyramide as a 19F MRI tracer, hydrocarbon oil, surfactants, and a NIR dye. Preparation utilizes a combination of self-assembly and high energy emulsification methods, resulting in droplets with average diameter 180 nm and low polydispersity index (PDI less than 0.2). A model nonsteroidal anti-inflammatory drug (NSAID), celecoxib, was incorporated into the formulation at 0.2 mg/mL. The reported nanoemulsion’s properties, including small particle size, visibility under 19F NMR and NIR fluorescence spectroscopy, and the ability to carry drugs make it an attractive potential theranostic agent for cancer imaging and treatment.
