A composition for facilitating delivery of biological agents, comprising a therapeutic or diagnostic agent and a supramolecular complex, the latter comprising (i) a block copolymer, having at least one nonionic, water soluble segment and at least one polyionic segment, and (ii) at least one charged surfactant having hydrophobic groups. The charge of the surfactant is opposite to the charge of the polyionic segment of the block copolymer. The constituents of the supramolecular complex are bound by interaction between the opposite charges thereof and between surfactant hydrophobic groups. The therapeutic or diagnostic agent may be an ionic substance, in which case the ionic substance has a net charge opposite to that of the block copolymer, the net charge being no more than 10.

Composition for delivery of biological agents and methods for the preparation thereof

A composition for facilitating delivery of biological agents, comprising a supramolecular complex including as constituents a block copolymer, having at least one nonionic, water soluble segment and at least one polyionic segment, and at least one charged surfactant having hydrophobic groups, the charge of the surfactant being opposite to that of the polyionic segment of the block copolymer. The constituents of the complex are bound by interaction between the opposite charges thereof and between surfactant hydrophobic groups. The complex may include an anionic surfactant having a biological activity, in which case the net charge of such anionic surfactant is no more than about 10.

Compositions for delivery of biological agents and methods for the preparation thereof

A method and composition are disclosed for providing a two-part polymer binder additive for a fibrous sheet for improving both its strength and durability. The two-part polymer binder may be added to augment organic binders to increase board strength and durability or to reduce the amount of organic binder required. The polymers may also be added in place of conventional organic binders or added in addition to organic binders to improve sag resistance and fibrous sheet performance.

Fibrous sheet binders

Improved pharmaceutical compositions useful in targeting biological agents to particular tissue and compositions useful for administering biological agents to the brain.
