Nanoparticles diluted in ultrapure water on 1: 1000 proportion, triplicate measurements, day 1. Control poly butyl-cyanoacrylate nanoparticles (PBCAnp) and nanoparticles loaded with polymyxin B 5 mg/mL (PBCAnp-polB); particle size distribution D10, D50, and D90 correspond to 10%, 50%, and 90% of total particles under the reported particle size value, respectively.
