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.

Abstract: Described herein are articles and methods of making articles, for example glass articles, comprising a thin sheet and a carrier, wherein the thin sheet and carrier are bonded together using a modification (coating) layer, for example a cationic polymer coating layer, and associated deposition methods, the carrier, or both, to control van der Waals, hydrogen and covalent bonding between the thin sheet and the carrier. The modification layer bonds the thin sheet and carrier together with sufficient bond strength to prevent delamination of the thin sheet and the carrier during high temperature (?600° C.) processing while also preventing formation of a permanent bond between the sheets during such processing.
