Resumen: Electrospray was used as a one-step technique to generate inhalable ciprofloxacin-loaded chitosan sub-micron particles with potential use in the treatment of pulmonary infections. The effect of operating parameters was studied and the preparation method optimized. The final sizes of ciprofloxacin-loaded particles were 386.1 +/- 248.5 nm and 501.1 +/- 276.3 nm for high and low molecular weight chitosan, respectively. The high surface charge of the particles formed, around +45 mV, enhances their mucoadhesive properties. The particles were biocompatible with alveolar cell line (A549), and showed a high antimicrobial activity against two of the most common respiratory pathogens Staphylococcus aureus and Pseudomonas aeruginosa.
