Release of lactic acid from (A) nanocarrier-based hydrogels, and (B) hydrogels with passively entrapped lactic acid at 37 °C, n=3; mean±SEM. (A) The nanocarrier-based hydrogels showed a controlled release of lactic acid with maximum release of 10% in PBS and 14% in AB. (B) The hydrogels with passively entrapped lactic acid showed a burst release of lactic acid in PBS with 90% and 80% lactic acid released from 4% w/v and 6% w/v hydrogels, respectively within 30 min.
