Abstract
Composite nanomaterials represent a new trend in the biomedical field. Coupling inorganic/organic constituents with non-toxicity/biocompatibility properties leads to develop the new systems having special characteristics that can be used in various bio-applications. This paper describes the preparation and characterization of psyllium-based composites containing TiO2 nanoparticles in order to develop new therapeutic strategies for aspirin drug delivery. The structural characteristics of obtained materials were investigated by FTIR spectroscopy. The UV–vis spectrophotometric analysis was performed to evaluate the aspirin release behavior under different pH conditions at 37°C. Combining psyllium (as an excellent source of fiber) with TiO2 inorganic unit (as vehicle of aspirin) it was found that polymeric-TiO2 networks have promising potential for controlled aspirin release as therapeutic agent.
