| abstract |
The present invention is embodied by a composition that is capable of entailing a therapeutically or diagnostic agent, typically non-orally available, through the gastrointestinal tract such that the therapeutic or diagnostic agent is bioavailable. The composition may or may not target specific cell receptors, such as hepatocytes. Therapeutic agents include, but are not limited to, insulin, calcitonin, serotonin, and other proteins. Targeting is achieved by biotin or metal-based targeting agents. |
