外源性药物的输送可以实现非侵入性疾病监测,但现有的低剂量方法需要复杂的基础设施。在本文中,我们描述了一种微剂量规模的纳米颗粒注射制剂,询问凝血酶的活性,凝血酶是凝血的关键调节因子,并产生疾病状态的尿报告。我们建立了一个定制的单分子检测试验,使尿中的血栓栓塞性疾病的小鼠使用的剂量的纳米颗粒诊断剂,属于监管准则的“微剂量”的歧视。
The delivery of exogenous agents can enable noninvasive disease monitoring, but existing low-dose approaches require complex infrastructure. In this paper, we describe a microdose-scale injectable formulation of nanoparticles that interrogate the activity of thrombin, a key regulator of clotting, and produce urinary reporters of disease state. We establish a customized single molecule detection assay that enables urinary discrimination of thromboembolic disease in mice using doses of the nanoparticulate diagnostic agents that fall under regulatory guidelines for “microdosing.”
