Abstract

A pH-switchable carrier composition includes a plurality of bioactive glass particles, wherein each of the bioactive glass particle is optionally at least a partially coated with a surface modifier; wherein the bioactive glass particles, with or without, the surface modifier can bind to a nucleic acid compound upon contact at pH in the range of about 7 to about 11, and exhibit controlled release of the nucleic acid compound at pH in the range of about 5 to 6.
