Materials and methods for multidirectional biotransportation in virotherapeutics

A process for making a molecule that specifically binds to more than one target molecule, the process comprising:

• a step for performing a function of obtaining a binding domain capable of binding to pIgR on mucosal endothelium;
• a step for performing a function of obtaining a binding domain capable of binding to a second target on a second cell or a virus;
• and
• a step for performing a function of providing a molecule capable of binding to a pIgR antigen on mucosal endothelium and a second target on a second cell or a virus optionally wherein the step for performing a function of obtaining a binding domain capable of binding to a second target is repeated n times and further comprising n steps for performing a function of providing a binding domain capable of binding to a pIgR on mucosal endothelium and n number of target molecules, wherein n is at least 2.
