Biomaterials are divided into various classes. One of them is bioceramics. Ceramics such as hydroxyapatite (HA), tricalcium phosphate (TCP), which form the inorganic part of the composite, are widely used in biomedical implant applications and bone regeneration due to their bioactive and biodegradable properties. In this study, bioceramic (HA, Florapatite (FA), TCP) synthesis was performed from human tooth minerals. Structural (X-ray Powder Diffraction (XRD), Fouirer Transform Infrared Spektrofotometre (FTIR)) and morphological-elemental (Field Emission Gun Scanning Electron Microscopy (FEGSEM)- Energy dispersive X-ray spectroscopy (EDS)) analyzes of the bioceramic structure have been performed to characterize the materials that can be used in major tissue engineering applications. © 2018 IEEE. 4th Electric Electronics, Computer Science, Biomedical Engineerings' Meeting, EBBT 2018 -- 18 April 2018 through 19 April 2018 -- Mon, 01 Jan 2018 00:00:00 GMT https://hdl.handle.net/20.500.12294/1929 2018-01-01T00:00:00Z https://hdl.handle.net/20.500.12294/1897 Electrohydrodynamic atomization (EHDA) technique for the health sector of polylactic acid (PLA) nanoparticles Buluş, Erdi; İsmik, Deniz; Mansuroğlu, Demet Sezgin; Fındıkoğlu, Maral Selin; Bozkurt, Bahadır; Şahin, Yeşim Müge; Doğancı, Erdinç; Doğancı Dandan, Merve; Sakarya, Gülseren Polylactic acid (PLA) is a kind of environmental thermoplastic polymer. Aliphatic polyesters, such as PLA, are a biocompatible polymer with mechanical properties, transparencies and non-toxic properties. These properties are used in consumer products such as packaging, automobile, furniture, food, textile and pharmaceutical industry. In this study, PLA nanoparticle was produced by electrohydrodynamic atomization (EHDA) which is a nanotechnological method. The EHDA system produces micro or nanoparticles by providing an optimization network in the case of high pressure and controllable controllability. Structural properties of the produced nanoparticles (Fourier Transformed Infrared Spectroscopy (FTIR)), thermal (Differential Scanning Calorimeter (DSC)) and morphological (Field Emission Gun Scanning Electron Microscopy (FEGSEM)) characterization studies were made and their properties were determined. PLA nanoparticles with biodegradable properties can be used both as a master and as an additive in clean air filter, tissue engineering and biomedical applications. © 2019 IEEE. 2019 Scientific Meeting on Electrical-Electronics and Biomedical Engineering and Computer Science, EBBT 2019 -- 24 April 2019 through 26 April 2019 -- Tue, 01 Jan 2019 00:00:00 GMT https://hdl.handle.net/20.500.12294/1897 2019-01-01T00:00:00Z https://hdl.handle.net/20.500.12294/1894 İyonik jelleşme yöntemi ile aloe vera yüklü kitosan nanopartikül sentezi Ismık, Deniz; Fiındıkoğlu, Maral Selin; Mansuroğlu, Demet Sezgin; Buluş, Erdi; Şahin, Yeşim Müge Aloe Vera, a long-lived and xeromorphic plant, is known for its therapeutic properties. Several beneficial effects have been reported including AV, hypoglycemic, wound and burn healing, gastroprotective, anticancer, antifungal and anti- inflammatory properties. Chitosan, a biocompatible and biodegradable polymer, has attracted the interest of scientists in recent years thanks to its antibacterial, antimicrobial and antifungal effects. In this study, production of AV loaded chitosan nanoparticles was investigated. Tripolyphosphate (TPP) was used as crosslinker. Field Emission Gun Scanning Electron Microscopy (FEG-SEM) was used to determine the surface characterization and size of chitosan nanoparticles produced by ionic gelation technique. In addition, UV-Spectrometry was used to determine the amount of AV loaded into the produced nanoparticles. AV loaded chitosan nanoparticles produced in this study, as well as antibacterial and antifungal properties, as well as the active substance loading capacities are high and can be designed according to the desired area in many areas (cosmetics, pharmaceuticals, biomedical and tissue engineering, etc.) can be used as a candidate material. © 2019 IEEE. 2019 Scientific Meeting on Electrical-Electronics and Biomedical Engineering and Computer Science, EBBT 2019 -- 24 April 2019 through 26 April 2019 -- Tue, 01 Jan 2019 00:00:00 GMT https://hdl.handle.net/20.500.12294/1894 2019-01-01T00:00:00Z https://hdl.handle.net/20.500.12294/1580 Synthesis and Characterization of Hydroxyapatite Powders From Eggshell For Functional Biomedical Application Buluş, Erdi; İsmik, Deniz; Mansuroğlu Sezgin, Demet; Şahin, Yeşim Müge; Tosun, Gül Apatitic phosphates are considered within the category of bioceramics. HA and its derives are used of in the fields of medicine, orthopedics and dentistry in order to support a grow up of new bone cells. HA structures have a high biocompability and are widely in biomedical applications. On the other hand, synthesis of HA structures necessitates complex technologies (microwave sintering, hydrothermal synthesis etc.) and their production costs high. This study aims the production of nano apatitic structures with great biocompability from a natural material. Simple hotplate method was used to obtain natural, nano scale HA from eggshells. After calcination and sintering processes at different temperatures, the obtained apatitic phosphate powders have been structurally characterized by infrared spectroscopy (FT-IR) and X-ray diffraction (XRD). Morphological investigation has been conducted by FEG-SEM images. Biological investigations have been carried out for the produced nanosized bioceramics and the results reveal that these nanomaterials are promising for tissue engineering purposes.
