pH-sensitive nanoparticles formed by interchain hydrogen boding of poly(methacrylic acid-block-ethylene oxide) (PMAA-b-PEO) copolymers were prepared and investigated at pH < 5. Both the molecular weight Mw and the hydrodynamic radius Rh of nanoparticles increase with decreasing pH of solution.
pH citlivé nanočástice byly připravené při pH < 5 asociací blokového kopolymeru poly(kyseliny methakrylové-blok-oxidu ethylenu) (PMAA-b-PEO) vodíkovými vazbami. Molekulární hmotnost Mwa hydrodynamický poloměr Rh nanočástic rostl s klesajícím pH roztoku.
