Figure 3. Different types of anchoring groups in covalent binding immobilization strategies^[71]. (A) Carboxylate anchoring through chelating, unidentate, or bridging binding; (B) phosphonate anchoring through mono-, bi-, and tridentate binding; (C) silatrane anchoring through mono-, bi-, or tridentate binding; (D) hydroxamate anchoring through chelating, unidentate, and bridging binding; and (E) acetylacetonate anchoring through chelating and bridging binding.
