titleOfInvention | Materials and methods related to polyion and substance delivery |
abstract | A material and method for delivering a desired substance to a target site, wherein the carrier and the substance together form at least three layers that associate by ionic interaction at a first pH, wherein the at least one layer comprises: Containing an ionizable group, including a charge conversion material having a positive charge at a first pH, a smaller positive, neutral or negative charge at a second pH, wherein at least one layer is negative at a first pH Disclosed is a layered carrier containing charged polyions and at least one layer containing a desired substance. Preferred carriers are based on polyBis-Tris which is a charge conversion material and polyacrylic acid which is a polyionic polymer. |
