A rod-shaped plant virus having an interior surface and an exterior surface, and at least one imaging agent that is linked to the interior and/or exterior surface is described. The rod-shaped viruses can be combined into larger spherical nanoparticles. A rod-shaped plant virus or spherical nanoparticles including an imaging agent can be used in a method of generating an image of a tissue region of a subject such as a tumor or atherosclerotic tissue by administering the virus particle to the subject and generating an image of the tissue region of the subject to which the virus particle has been distributed.
本文描述了一种具有内表面和外表面的杆状植物病毒,以及至少一种与内表面和/或外表面相连的成像剂。杆状病毒可组合成较大的球形纳米颗粒。杆状植物病毒或包括成像剂的球形纳米粒子可用于生成受试者组织区域(如肿瘤或动脉粥样硬化组织)图像的方法中,具体方法是将病毒颗粒施用于受试者,并生成受试者组织区域的图像,病毒颗粒已分布到该组织区域。
