The invention comprises compositions and methods useful for encapsulation and controlled release of guest molecules, such as drugs. Compositions of the present invention comprise a matrix comprising molecules that are non-covalently crosslinked by multi-valent cations, wherein the molecules that are non-covalently crosslinked are non-polymeric, have more than one carboxy functional group, and have at least partial aromatic or heteroaromatic character The compositions are characterized in that a guest molecule may be encapsulated within the matrix and subsequently released.
该发明包括用于封装和控制释放客体分子(如药物)的组合物和方法。本发明的组合物包括一个基质,该基质由多价阳离子非共价交联的分子组成,其中非共价交联的分子是非聚合物,具有多于一个羧基官能团,并且具有至少部分芳香或杂环芳香性质。该组合物的特点在于,客体分子可以被封装在基质内,并随后释放。
