Figure 3. PLA nanoparticles do not induce cell toxicity
Concentrations of PLA NPs up to 4 mg/ml (and a contact time as long as 48 h) did not induce cell toxicity or any detectable interference with the metabolic and proliferation abilities of the cultured RPE cells. The number of viable cells per well on day 4 of cultured bovine RPE cells incubated with increasing concentrations of blank nanoparticles for 48 h. The number of viable cells within the different cultures remained similar without significant differences between them (p<0.05).
