As these days we use a wide range of nano particles that are made from different materials while following different methods, the use of the polystyrene micro particles is also on the rise. As far as the polystyrene is concerned, this is the mostly used plastic material. This plastic material is used for the making of a wide range products and applications. When the styrene monomers are polymerized, the polystyrene like plastic material is obtained. Now the top quality polystyrene microspheres 1μm are announced in cheap and these micro particles are in great demand in the biomedical field and for the applications that are used for such sector.
