wherein in Formula I, at least one of R.sup.1 to R.sup.4 is —COOR.sup.5 and R.sup.5 is —C.sub.0-C.sub.10alkyl(C.sub.2-C.sub.10alkynyl) or —C.sub.0-C.sub.10alkyl-C.sub.2-C.sub.10alkenyl(C.sub.2-C.sub.10alkynyl), preferably a terminal alkynyl. The bifunctional linker is used in a cycloaddition to tether two entities, for example a protein or antibody, and an active agent, to form a bisconjugate. The bifunctional linker also be used to form a conjugate, followed by cycloaddition in the presence of a comonomer composition to form a bisconjugate including a protein or antibody linked to an adhesive polymer network. Catalysis can be provided by a copper-containing paint on a surface to adhere the bisconjugate to the surface. Methods of synthesis and use of the bisconjugates imaging, diagnostic, and therapeutic applications are also described.
