Nanoparticle response to temperature at different pH values (G1) when (a) acrylic acid, (b) 8-nonenoic acid and (c) 9-decenoic acid were used as comonomers with NIPAm. (d) ION − IOFF was calculated at for (a), (b), and (c) at (43–37°C), (41–35°C) and (39–33°C), respectively. ION − IOFF was significantly increased between pH 7.4 and 6.8 for (b) and (c) (p-values 0.0399 and 0.0218) as well as 7.4 and 6.2 (p-values 0.0364, 0.0048, respectively.)
