Kalsiyum aljinat seryum oksit nanokompozit malzemelerin şişme özellikler

Biopolymer-nanoparticle composites are one of the emerging materials in the interdisciplinary applications for biomedical science, mechanical engineering and chemistry. This kind of materials exhibit very useful properties such as biocompatibility, high surface area, and drug entrapment. Especially for biological applications, swelling properties of the materials are one of the very important parameters. Sustained release and diffusion parameters of the biochemical agents and drugs are related to the absorption of the liquid which the nanocomposite matrix is in contact with. In this experimental study, the swelling parameters of cerium oxide-calcium alginate nanocomposites in three different liquid medium, namely pure water, isotonic sodium chloride solution, and simulated gastric fluid is investigated. Here, nanoparticles of cerium oxide are synthesized by cerium-alginate biopolymer route and then dispersed in sodium alginate solution in order to achieve a homogeneous dispersion. Due to the origin of the nanoparticles, to the best of our knowledge, this kind of study is also reported for the first time in the literature. Keywords: cerium oxide, alginate, nanocomposite, swelling.
