Effect of the pH value of the environment on the release of payloads from NCs prepared with (A) ketone-functionalized dextran (KeDNC0.5) and (B) aldehyde-functionalized dextran (OxDNC0.5). Using rhodamine-functionalized dextran as the payload with a molecular weight (1) Mn = 150 kDa and (2) Mn = 500 kDa. Measured at a pH value of 7.4 (■), 6.0 (●), and 5.2 (▲).
