- Hypothesis: Biopolymer–CaCO3 hybrid microparticles exposed to hydrolytic enzymes can provide new surface tailorable architectures. Soluble Alginate Lyase hydrolyzed alginate chains exposed on microparticle surface are generating considerable matrix changes. The change of porosity and surface to volume ratio is expected to influence absorption of drugs, thereby affecting controlled release profiles. The developed hybrid system potentially shows interesting properties for lung drug administration. Experimental: Hybrid microparticles were developed by colloidal co-precipitation of CaCO3 in presence of biopolymers: alginate (Alg) or Alg–High Methoxylated Pectin (HMP), followed by treatment with Alginate Lyase (AL). Surface architectures were observed by SEM. The increase in area to volume ratio was confirmed by BET isotherms. Also, enzymatic changes were elucidated by biophysical methods (EDAX, DSC, FTIR, XRD) and determination of the total carbohydrates content. Levofloxacin (a fluoroquinolone antibiotic) as model drug was incorporated by absorption. The drug release profile and the antimicrobial activity of the microparticles were tested against Pseudomonas aeruginosa. Findings: After enzyme treatment, microspheres showed 4 μm diameter and increased porosity. While CaCO3–Alg microspheres resulted in a rougher surface, CaCO3–Alg–HMP ones exhibited “nano-balloon” patterns on surface. Both AL-treated microparticles showed up to 3 and 7 times higher Levofloxacin encapsulation than no treated ones. Microparticles showed controlled drug release profiles and enhanced antimicrobial effect. The present work demonstrates a significant progress in the development of new carriers with potential application for lung infections treatment.
