    Vitamin B12-hyperbranched polymer was synthesized and characterized by UV-vis and NMR spectroscopy as well as DLS. The shape of hybrid polymer was also directly observed by TEM. Microenvironmental polarity around vitamin B12 derivative on the polymer was evaluated by UV-vis absorption peak with α-band of vitamin B12 chromophore.
