  • Pulsed bio-agent delivery systems based on degradable polymer solutions or hydrogels
    Publication number: 20040258753
    Abstract: A degradable oligomer or polymer aqueous solution or a degradable polymer hydrogel, wherein degradation occurs by cleavage of the oligomer or polymer backbone and/or, in the case of a hydrogel, by cleavage of cross-linking bonds within the hydrogel, is useful as a component of a time-controlled explosion bio-agent release system or a pulsed bio-agent delivery system comprising at least one biologically active agent and an outer semi-permeable lipid or polymer membrane, wherein bio-agent release or delivery begins after a lag time.
