This invention is something which offers the method at least of locking the carbohydrate molecule of 1 kinds, this method becomes, a certain surface the surface which was covered with the plasma polymer by the fact that at least it makes contact with the plasma of the monomer of 1 kinds including the fact that the occurring and the aforementioned polymer surface are made to contact with the carbohydrate molecule.本発明は、少なくとも1種の炭水化物分子を固定する方法を提供するものであり、この方法は、ある表面を少なくとも1種の単量体のプラズマと接触させることでプラズマ重合体で被覆された表面を生じさせそして前記重合体表面を炭水化物分子と接触させることを含んで成る。
