Article Citation - WoS: 24Citation - Scopus: 28Development of Amoxicillin-Loaded Electrospun Polyurethane/Chitosan Β-Tricalcium Phosphate Scaffold for Bone Tissue Regeneration(Ieee-inst Electrical Electronics Engineers inc, 2018) Topsakal, Aysenur; Uzun, Muhammet; Ugar, Gaye; Ozcan, Aslihan; Altun, Esra; Oktar, Faik Nuzhet; Gunduz, OguzhanBiocompatible nanocomposite electrospun fibers containing Polyurethane/Chitosan/beta-Tri calcium phosphate with diverse concentrations were designed and produced through the electrospinning process for bone tissue engineering applications. After the production process, density measurement, viscosity, electrical conductivity, and tensile strength measurement tests were carried out as physical analyses of blended solutions. The chemical structural characterization was scrutinized using Fourier transform infrared spectrometer (FTIR), and scanning electron microscopy (SEM) was used to observe the morphological details of developed electrospun scaffolds. Cell viability, attachment, and proliferation were performed using a L929 fibroblast cell line. Based on the physical, SEM, FTIR analysis, and cell culture studies, preferable nanofiber composition was selected for further studies. Amoxicillin (AMX) was loaded to that selected nanofiber composition for examination of the drug release. In comparison with other studies on similar AMX controlled products, higher drug loading and encapsulation efficiencies were obtained. It has been clearly found that the developed nanofiber composites have potential for bone tissue engineering applications.Book Part Citation - WoS: 18Citation - Scopus: 23Stem Cell and Advanced Nano Bioceramic Interactions(Springer-verlag Singapore Pte Ltd, 2018) Kose, Sevil; Kankilic, Berna; Gizer, Merve; Dede, Eda Ciftci; Bayramli, Erdal; Korkusuz, Petek; Korkusuz, FezaBioceramics are type of biomaterials generally used for orthopaedic applications due to their similar structure with bone. Especially regarding to their osteoinductivity and osteoconductivity, they are used as biodegradable scaffolds for bone regeneration along with mesenchymal stem cells. Since chemical properties of bioceramics are important for regeneration of tissue, physical properties are also important for cell proliferation. In this respect, several different manufacturing methods are used for manufacturing nano scale bioceramics. These nano scale bioceramics are used for regeneration of bone and cartilage both alone or with other types of biomaterials. They can also act as carrier for the delivery of drugs in musculoskeletal infections without causing any systemic toxicity.
