Abstract:
A method for manufacturing a bioactive glass ceramic material is firstly to prepare a calcium phosphate series ceramic material and a nano-scaled titanium dioxide powder with a specific proportion of anatase type titanium dioxide structure. Then, the calcium phosphate series ceramic material and the nano-scaled titanium dioxide powder are mixed according to a specific proportion for obtaining a mixture. The mixture is then melted and quenched to form a biomedical glass. Finally, the biomedical glass can be further ground into a biomedical glass powder, and a heat treatment can be applied to recrystalize the powder so as to obtain the bioactive glass ceramic material. Also, the bioactive glass ceramic material can be further polarized into a electrified bioactive glass ceramic material which can promote the growth of a broken bone.
Abstract:
The invention provides new methods for synthesizing oligonucleotides that allow for deprotection of the oligonucleotides under more mild conditions than existing methods. The invention further provides a nucleoside base protecting group that is stable under oligonucleotide synthesis conditions, but which can be removed under more mild conditions than existing protecting groups, as well as nucleoside synthons having such base protecting groups.
