Ozon Yağı İçeren Nanoteknolojik Yara Örtüsü Üretimi ve Karakterizasyonu
No full textBu çalışmada suda kolay çözünebilmesi, kolay spinlenebilmesi, nitelikli nanofiber yüzeyler oluşturabilmesi gibi özellikleri bakımından elektroeğirme yöntemi için oldukça kullanışlı olan polivinil alkol (PVA) kullanılmıştır. Hassas terazide tartılarak granül haldeki PVA ile saf suyun kütlece %10’luk karışımı hazırlanmıştır. Karışım ısıtıcılı manyetik karıştırıcıda 80 ºC sıcaklıkta 3 saat boyunca karıştırılmış ve 24 saat boyunca oda sıcaklığında bekletilmiştir. Oluşan %10’luk PVA çözeltisine %5 oranında ozon yağı maddesi katılarak 45 dakika 30 ºC sıcaklıkta manyetik karıştırıcıda karıştırılmıştır. %10 PVA, %10 PVA-%5 Ozon Yağı kompozitleri elektroeğirme tekniği ile elde edilmiştir. Elde edilen kompozitlerin Alan Emisyon Tabancalı Taramalı Elektron Mikroskobu (FEGSEM) ile morfolojik karakterizasyonları gerçekleştirilmiştir. Diyabet hastaları başta olmak üzere kronik yaralara yönelik ürettiğimiz membranlar hızlı yara iyileştiri özellikleri ile ideal malzeme adayı olabilecektir
A Review Polylactic Acid and Gelatin Biomaterial GBR (Guided Bone Regeneration) and Multilayer GBR Membranes
No full textThe reflections of the rapid development of technology are clearly seen in the health sector, especially in the field of tissue engineering. The road covered by tissue engineering and nanotechnology branches is frequently encountered in the field of innovative medical devices. It is an undeniable fact that the innovations brought by materials science in the dental field such as dental prostheses and implants within the scope of medical devices increase the quality of life. There are various brands and models of oriented bone membrane (GBR) membrane systems in the dental medical market. The subject of this review is to examine the general properties of GBR systems, which is an innovative medical device, and to make a general evaluation in terms of osteoconductivity. The purpose of this review is to examine GBR membrane systems as an overview of GBR membrane systems and multilayer GBR applications made from gelatin (GEL) and polylactic acid (PLA) polymers, which are easy to find as materials and more affordable in price. In addition, it is aimed to contribute to the work of young scientists who will work on GBR membrane systems
Electrohydrodynamic Atomization (EHDA) Technique for the Health Sector of Polylactic Acid (PLA) Nanoparticles
No full textPolylactic 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
