Interactions between tritiated gliadin and zein nanosystems and various human cell lines as a function of incubation times. (A): Freeze-dried cryoprotectant-free gliadin nanoparticles prepared with 1 mg/mL of polymer and 0.1% w/v of SRO2. (B): Freeze-dried cryoprotectant-free zein nanoparticles prepared with 2 mg/mL of polymer and 1.25% w/v of SD. (C): Freeze-dried gliadin nanoparticles containing 10% w/v of mannose as cryoprotectant. (D): Freeze-dried zein nanoparticles containing 10% w/v trehalose as cryoprotectant. Results are the mean of three different experiments ± standard deviation. * p < 0.05, ** p < 0.001 (with respect to the untreated cells).
