Interactions with Organic Molecules

Many of the molecules that constitute living organisms, such as amino acids, enzymes, proteins, and DNA, are chiral and present in only one of the two enantiomeric forms. When small, chiral organic molecules interact with the homochiral molecules of biological... 

Organic compounds interact with each other and with the inorganic, macro, micro, and colloidal components in soil. Complex and simple organic molecules form complexes with inorganic cations and anions and with colloidal... 

Therapeutic and toxic effects of drugs result from their interactions with molecules in the patient. Most drugs act by associating with specific macromolecules in ways that alter the macromolecules biochemical or biophysical activities. This idea, more than a century old, is embodied in the term receptor the component of a cell or organism that interacts with a drug and initiates the chain of events leading to the drug s observed effects. 

Many PSPs are composed of probe dyes, such as polycyclic aromatic hydrocarbons (e.g., pyrene) and coordination compounds (e.g., platinum por-phryins and ruthenium(II) polypyridyl complexes) immobilized in various gas permeable polymer films such as silicon polymer, organic glassy polymers (e.g., poly(methylmethacrylate), polystyrene), fluorinated polymers, or cellulose derivatives such as ethyl cellulose [9,10]. As probe molecules interact with polymer matrices directly, the properties of PSPs strongly depend on the properties of polymer matrices. The oxygen permeability of polymer matrix is an especially important factor for highly sensitive PSP.
