摘要：
Polymeric particles are provided for use in therapeutic and/or diagnostic procedures.The particles include poiy[bis(trifluoroethoxy) phosphazene] and/or a derivativesthereof which may be present throughout the particles or within an outer coatingof the particles. The particles may also include a core having a hydrogel formedfrom an acrylic-based polymer. Such particles may be provided to a user in specificselected sizes to allow for selective embolization of certain sized blood vesselsor localized treatment with an active component agent in specific clinical uses.Particlesof the present invention may further be provided as color-coded microspheresor nanospheres to allow ready identification of the sized particles in use. Suchcolor-coded microspheres or nanospheres may further be provided in like color-coded delivery or containment devices to enhance user identification and providevisual confirmation of the use of a specifically desired size of microspheresor nanospheres.
