Abstract: A hydrogel network includes a hydrogel polymer having a coupling site, an oligonucleotide conjugated at a terminal end to the hydrogel polymer at the coupling site, and a functional moiety coupled between the terminal end of the oligonucleotide and the coupling site. Such a hydrogel network can be formed by a method including activating a coupling site of a substrate and binding a linker moiety coupled to a terminal end of an oligonucleotide to the activated coupling site, a functional moiety coupled between the terminal end of the oligonucleotide and the linker moiety.

Abstract: A polymer substrate, such as a polymer coating or a polymer hydrogel network, includes carboxyl moieties that can be used as conjugation sites to which receptor or analyte molecules can be attached. In an example, the polymer substrate includes a polyacrylamide polymer network having alkanoic acid moieties or derivatives thereof, which can react with carboxyl activating compounds to provide an activated alkanoate moieties on the polyacrylamide network. Amine-terminated nucleic acids can react with the activated alkanoate moieties to capture the nucleic acid to the polymer network through an alkylamide moiety.

Abstract: A method of conjugating a substrate includes exchanging a counter ion associated with a biomolecule with a lipophilic counter ion to form a biomolecule complex, dispersing the biomolecule complex in a nonaqueous solvent, and coupling the biomolecule complex to a substrate in the presence of the nonaqueous solvent.
