An osteosynthesis device is provided. A slit is formed in the plate between the opening and at least one edge of the plate. The dendritic polymer platinates exhibit high drug efficiency, high drug carrying capacity, good water solubility, good stability on storage, reduced toxicity, and improved anti-tumor activity in vivo. be a mold for the manufacturing of wind turbine blades or such blades. A variety of ways of affecting the efficacy of the process are described, such as varying the time the aqueous solution is exposed to the MIPS or varying the quantity of MIPS that the aqueous solution is exposed to.
