Methods of binding biomolecules to a substrate are provided that include contacting the biomolecule with a branched linking moiety to form a branched linking structure. The branched linking structure is then contacted with a binding moiety on the substrate to form a coupled substrate binding structure, thereby binding the biomolecule to the substrate. The biomolecule may contain a Lewis base or a nucleophile to react with a Lewis acid or electrophile in the branched linking moiety. Alternatively, the biomolecule may contain a Lewis acid or electrophile that can react with a Lewis base or nucleophile in the branched linking moiety. Additionally, the biomolecule can be bound to the substrate through a covalent or non-covalent bond.
