< Topic >Offer of the new vitreous substance, and its use which are stabilized the biological material.SolutionsIncluding the substance which includes the useful vitreous material in stabilization of the biological material and the biological material, being the composition which becomes, the composition which features that the description above itself at least includes one gas cavity. And, being production method of the vitreous product, when it generates the gas from process and II) particular 2nd material which mix the 2nd material which can produce the 1st liquid material and which can form i) glass to generate the gas, including the process which makes the glass the 1st material form simultaneously, including the glass which becomes, includes the gas with that the method of making vitreous construction ones form which become.< Selective figure >Figure 1【課題】生物学的材料を安定化させる新規なガラス質物質、及びその使用の提供。【解決手段】生物学的材料と、生物学的材料の安定化に有用なガラス質の材料を含む本体を含んでなる組成物であって、前記本体が少なくとも1つのガス空洞を含むことを特徴とする組成物。並びに、ガラス質の生成物の製造方法であって、i)ガラスを形成できる第1の液体材料と、ガスを発生させることができる第2の材料を混合する工程と、ii)当該第2の材料からガスを発生させるのと同時に第1の材料にガラスを形成させる工程を含んでなり、それによりガスを含むガラスを含んでなるガラス質の構築物を形成させる方法。【選択図】図1
