Calcium carbonate (CaCO3) is a widely used material in biomedical applications owing to its biocompatibility and widespread occurrence in nature, especially in the exoskeletons of marine organisms. The ability to undergo polymorphic transformation between CaCO(3)polymorphs in aqueous environments provides a wide range of applications in the biomedical field, i.e. vaterite can gradually dissolve to release drugs or calcite can provide rigidity as a bone regeneration material. In this study, CaCO(3)particles including ellipsoidal vaterite, bowknot-like aragonite, and rhombohedral calcite were synthesized via solution mixing method by altering precursor ratio, pH, temperature, and solvent concentration. Afterwards, CaCO(3)particles were interacted with human bone cells (hFOB) to assess cellular proliferation for orthopedic applications. Results showed that hFOB cell viability can be altered by the polymorph and concentration of CaCO(3)particles. As an important finding, while proliferation of hFOB cells was promoted up to 5 days in vitro upon the interaction with vaterite and calcite particles, cellular proliferation was inhibited by aragonite particles at the highest particle concentration. Therefore, this work systematically showed the potential use of different CaCO(3)polymorphs in orthopedic applications.

Synthesis of calcium carbonate particles for biomedical applications Oral, Çağatay Mert; Ercan, Batur; Department of Metallurgical and Materials Engineering (2020) Calcium carbonate (CaCO3) particles have been widely used in biomedical applications owing to their biocompatibility and biodegradability. In order to effectively utilize CaCO3 particles in biomedical applications, their physical and chemical properties should be systematically controlled. However, this is a challenging task due to the presence of three different anhydrous CaCO3 polymorphs having complex crystallization behavior. In this thesis, CaCO3 particles were synthesized at distinct environments to c...
Influence of pH on morphology, size and polymorph of room temperature synthesized calcium carbonate particles Oral, Cagatay M.; Ercan, Batur (2018-11-01) Calcium carbonate (CaCO3) particles have been used in various applications, including medicine, drug delivery and orthopedics. Having three different polymorphs and exhibiting complex crystallization behavior, it is a challenging task to systematically control physical properties of CaCO3 particles for desired applications. Herein, the influence of pH and [Ca2+]:[CO32-] ratio on the morphology, size and polymorph of room temperature synthesized CaCO3 particles were investigated. Although, in literature, eth...
Synthesis of calcium carbonate microspheres via inert gas bubbling for orthopedic applications Oral, Cagatay M.; Caliskan, Arda; Goctu, Yagmur; KAPUSUZ, DERYA; Ercan, Batur (Elsevier BV, 2020-02-15) Calcium carbonate (CaCO3) microspheres consisting of vaterite polymorph have been widely used in biomedical applications. Specifically, vaterite microspheres having hollow cores showed significant potential in drug delivery, however the spontaneous transformation of vaterite to other polymorphs in aqueous environments reduced its controlled in vivo release capability. In this work, calcite and aragonite microspheres having hollow/porous inner cores were synthesized -for the first time-using sodium dodecyl s...
Synthesis and applications of ion incorporated amorphous calcium-magnesium carbonate Göçtü, Yağmur; Ercan, Batur; Department of Metallurgical and Materials Engineering (2023-1-18) Amorphous calcium carbonate (ACC) can be synthesized using co-precipitation technique and different ions can typically be incorporated into its amorphous structure to enhance its stability. Although ACC was investigated for various applications, its antibacterial properties have not been explored. In this thesis, two different types of magnesium stabilized amorphous calcium carbonate (ACMC) nanoparticles were synthesized for antibacterial applications. In the first part selenite ions, and in the secon...
Removal of imidacloprid from wastewaters by ozonation and photo-ozonation Sönmez, Büşra; Dilek, Filiz Bengü; Department of Environmental Engineering (2019) The widespread occurrence of micropollutants in the receiving water bodies apparently shows that conventional wastewater treatment plants (WWTP) are not capable to remove these compounds. Imidacloprid (IMI), which is a specific pollutant and an insecticide, exceeded Environmental Quality Standards (EQS) value (0.14 µg/L, annual average) in several receiving water bodies of WWTPs in Yeşilırmak basin. With the aim of examining advanced treatment methods to meet EQS value and to achieve good surface water qual...
