    • A first method for medically imaging a patient includes obtaining a carrier medium containing fluorescent nanoparticles. The carrier medium containing the fluorescent nanoparticles is disposed inside the patient at a site where the carrier medium will migrate to specific tissue of known shape. The nanoparticles are activated to fluoresce. Image data of the patient is obtained including the specific tissue after the specific tissue has picked-up the fluorescing fluorescent nanoparticles. The known shape of the specific tissue is identified in the image data. An image representation of the image data is created using the identified known shape as a fiducial. An image of the image representation of the image data is displayed. In a second method, the carrier medium is injected inside tissue of the patient at a site where the carrier medium will be localized in the injected tissue, and the injecting deposits the medium in a predetermined shape in the tissue.
    • 用于医学成像患者的第一种方法包括获得含有荧光纳米颗粒的载体介质。 含有荧光纳米颗粒的载体介质在载体介质将迁移到具有已知形状的特定组织的位置处置于患者体内。 纳米颗粒被激活以发荧光。 在特定组织拾取荧光荧光纳米颗粒后,获得包括特定组织的患者的图像数据。 在图像数据中识别特定组织的已知形状。 使用所识别的已知形状作为基准来创建图像数据的图像表示。 显示图像数据的图像表示的图像。 在第二种方法中,将载体介质注射到患者的组织内,在载体介质将被定位在注入的组织中的位置处,并且注射将培养基以预定形状沉积在组织中。

    • Various compositions, methods, and devices are provided that use fluorescent nanoparticles, which can function as markers, indicators, and light sources. The fluorescent nanoparticles can be formed from a fluorophore core surrounded by a biocompatible shell, such as a silica shell. In one embodiment, the fluorescent nanoparticles can be delivered to tissue to mark the tissue, enable identification and location of the tissue, and/or illuminate an area surrounding the tissue. In another embodiment, the fluorescent nanoparticles can be used on a device or implant to locate the device or implant in the body, indicate an orientation of the device or implant, and/or illuminate an area surrounding the device or implant. The fluorescent nanoparticles can also be used to provide a therapeutic effect.
    • 提供使用可用作标记物,指示剂和光源的荧光纳米颗粒的各种组合物,方法和装置。 荧光纳米颗粒可以由包围生物相容的外壳如二氧化硅壳的荧光团芯形成。 在一个实施方案中,荧光纳米颗粒可以被递送到组织以标记组织,使得能够识别和定位组织,和/或照亮组织周围的区域。 在另一个实施方案中,荧光纳米颗粒可用于装置或植入物以将装置或植入物定位在体内,指示装置或植入物的取向,和/或照亮装置或植入物周围的区域。 荧光纳米颗粒也可用于提供治疗效果。
