The term molecular recognition refers to the specific interaction between two or more molecules through noncovalent bonding such as hydrogen bonding, metal coordination, hydrophobic forces,〔"The Binding of Benzoarylsulfonamide Ligands to Human Carbonic Anhydrase is Insensitive to Formal Fluorination of the Ligand" Angew. Chem., Int. Ed., Volume 52, Issue 30, pp. 7714-7717 2003; DOI: 10.1002/anie.201301813〕〔"Water Networks Contribute to Enthalpy/Entropy Compensation in Protein–Ligand Binding" J. Am. Chem. Soc., 2013, 135 (41), pp 15579–15584; DOI: 10.1021/ja4075776〕 van der Waals forces, π-π interactions, halogen bonding, electrostatic and/or electromagnetic effects. In addition to these ''direct'' interactions as well solvent can play a dominant ''indirect'' role in driving molecular recognition in solution. The host and guest involved in molecular recognition exhibit molecular complementarity. ==Biological systems== Molecular recognition plays an important role in biological systems and is observed in between receptor-ligand,〔"The Binding of Benzoarylsulfonamide Ligands to Human Carbonic Anhydrase is Insensitive to Formal Fluorination of the Ligand" Angew. Chem., Int. Ed., Volume 52, Issue 30, pp. 7714-7717 2003; DOI: 10.1002/anie.201301813〕〔"Water Networks Contribute to Enthalpy/Entropy Compensation in Protein–Ligand Binding" J. Am. Chem. Soc., 2013, 135 (41), pp 15579–15584; DOI: 10.1021/ja4075776〕 antigen-antibody, DNA-protein, sugar-lectin, RNA-ribosome, etc. An important example of molecular recognition is the antibiotic vancomycin that selectively binds with the peptides with terminal D-alanyl-D-alanine in bacterial cells through five hydrogen bonds. The vancomycin is lethal to the bacteria since once it has bound to these particular peptides they are unable to be used to construct the bacteria’s cell wall. Recent work suggests that molecular recognition elements can be synthetically produced at the nano-scale,〔Zhang, Landry, Strano et al. Nature Nanotechnology 2013 http://www.nature.com/nnano/journal/v8/n12/full/nnano.2013.236.html〕 circumventing the need for naturally-occurring molecular recognition elements for the development of sensing tools for small molecules.
