31. Nafion can be manufactured with various cationic conductivities. 32. These compounds are nitrogenous cationic surface active agents. 33. Typical slow-response probes include cationic carbocyanines and rhodamines, and ionic oxonols. 34. It is a high charge density cationic polymer. 35. Cationic polymers such as chitosan promote cell adhesion.36. Also, the homopolymerization of alkyl vinyl ethers is achieved only by cationic polymerization. 37. Other links include Toll-like receptors, polyethyleneglycol, fusogenic and cationic lipids. 38. The charged catalyst can be cationic or anionic. 39. It has been described as a cationic metallosilanone. 40. Typical modified starches for technical applications are cationic starches, hydroxyethyl starch and carboxymethylated starches.
