Polyvinyl butyral nanobeads: preparation, characterization, biocompatibility and cancer cell uptake

Posavec, Damir ; Dorsch, Andre ; Bogner, Udo ; Bernhardt, Guenther ; Nagl, Stefan


We describe the synthesis of spherical poly(vinyl butyral) (PVB) nanobeads by controlled pptn. via addn. of non-solvent. Effects of various reaction parameters on nanoparticle size were investigated by dynamic light scattering and electron microscopy. The ability to incorporate dopant mols. was studied using a fluorescent perylene deriv. as a model additive, and the dye-doped nanoparticles were ...
