荧光标记物微粒由含有特殊荧光染料的聚合物合成，这种荧光染料采用手持式UV 灯(Wood's Lamp)即可被有效激发。
这种荧光是一种明亮的黄绿色。这种微粒是球形的，直径为 1-10 μm，密度为 1.05 g/cm3。因此此种微粒很容易悬浮于液体介质中。
Effectively mark the “risk zone” in evaluating regional ischemia with Thermo Scientific™ Fluoro-Max Green Particulate Marker Particles, brilliant yellow-green particles that lodge in the capillaries. Easily seen under fluorescent illumination, these particles are made of polymer containing a fluorescent dye that excites efficiently with a handheld UV lamp (i.e., Wood's Lamp). They are spherical, 1-10μm in diameter, and have a density of 1.05g/cm3, which makes them easy to suspend in an aqueous medium.
Various dyes and particulate markers have been used to mark the “risk zone” in evaluating regional ischemia. These include Evans Blue, India Ink and Fluorescein. However, these dyes tend to rapidly migrate throughout the tissue making the risk zone difficult to identify.
Fluorescent particulate markers are effective because they lodge in the capillaries and are easily viewed under fluorescent illumination. The particles are heavily loaded with dye, resulting in a very strong fluorescence that can easily be seen. They are invisible under white light, allowing the non-risk tissue to be examined for infarction. Since the dye is embedded in the interior of the particles, it does not leach out or cause indiscriminate staining.
