Ionic strength and pka
Webwere less effective at low pH and became more effective at high pH for both of ionic strength. Anions possessed a more potent effect on the zeta potential at high and low pH except for 0.1 M salts concentration at high pH. In general, isoelectric point of biomolecules changed with ionic environment. WebBesides pH of the solution, ionic strength of the medium determines the swelling behavior of these PDEAEMA-based NGs. According to PDEAEMA properties, an increase in pH of the solution led to a reduction of the VPTT showing values physiologically relevant (38 °C and pH 7.1) ( Figure 3 ) [ 25 ].
