Fluorescent Microspheres

Ocean NanoTech's carboxylated fluorescent microspheres are polystyrene based microspheres with monodispersed size ranging from 0.3 µm to 0.5 µm. The photostable fluorescent dye (europium chelate) is physically encapsulated in the microspheres, which prevents dye leaching. These fluorescent microspheres have a high density of carboxylic acid functionalized surface for targed protein or ligands immobilization. Fluorescent microspheres are a critical material for the application of IVD and life sciences.
