Abstract. In this review the properties of annealed, quenched and betainic (or zwitterionic) polyampholytes in solution and gel state are analyzed. The stimuli-responsive character of water- soluble and water-swelling polyampholytes exhibiting temperature-, salt-, pH-, solvent-, DC- and bio-sensitivity is considered. Self-healing and shape memory behavior of polyampholyte gels is also in the eyeshot of this review. Catalytic properties of metal nanoparticles and enzymes immobilized within macroporous polyampholyte cryogels to design stable, active and selective flow through catalysts in reactions of hydrolysis, hydrogenation and oxidation of various substrates are highlighted. Future perspectives in development of polyampholytes are outlined.
Key words. polyampholytes, stimuli-sensitivity, hydrogels, cryogels, catalysis
