Nowadays, biomaterials have attained great importance in medical sector owing to the urgent requirement of the material systems which can be suitable for different sorts of human body treatments. Among the various biomaterials available, commercially, polymeric materials occupy great importance because of their near-to-organ characteristics, biocompatibility, corrosion resistance, and other essential mechanical features. The current applications of biopolymers include scaffolding, load-bearing implants, intraocular lenses, artificial heart valves, cardiovascular prostheses, cardiopulmonary bypass, hemodialysis, and dental and orthopedic applications. Although there exist numerous established fabrication routes for biopolymers, yet, their post processing is often required in order to achieve required geometrical and topographical performances. Therefore, machining of the processed biopolymers is often required. The aim of this article was to present a crisp review of the machining of different biopolymers. Further, being an ultraprecision machining operation, specific attention has been paid on the diamond turning technique as well as a case study has been performed to study the effect of process parameters on the resulting characteristics. Overall, the current work will provide a unique platform which could be helpful for young biomedical engineers and scientists focusing on precision surface engineering.

Anahtar kelimeler Biyopolimerler Endüstriyel polimerler Ambalaj sektörü Doğal ve sürdürülebilir kaynaklar Özet Polimerler; istenilen özellikte sentezlenebilme, kolay işlenebilme, korozyona uğramama, hafiflik ve düşük maliyete sahip olma gibi özelliklere sahip gelişmiş materyallerdir. Sahip oldukları bu özellikler sayesinde polimerler, endüstride birçok kullanım alanı bulmuştur ve bu alanlar gün geçtikçe artmaktadır. Endüstriyel polimerler göstermiş oldukları yüksek potansiyel ve özelliklerin aksine, doğal bir süreç ile yok edilememesi sonucu kirlilik oluşturmakta ve ancak maliyetli parçalanma işlemleri sonucunda bertaraf edilebilmektedir. Bununla birlikte, petrol kaynakları gibi tükenir kaynaklardan elde edilmeleri, polimer sektöründe süreklilik ve çevre uyumu açısından yeni arayışlara yol açmıştır. Biyopolimerler, endüstriyel polimerlerin tükenir kaynaklardan elde edilmeleri ve bertarafının zor olması gibi dezavantajları sonucu, başta ambalaj sektörü olmak üzere birçok alanda alternatif materyal olarak ön plana çıkmıştır. Doğal ve sürdürülebilir kaynaklardan elde edilen biyopolimerler, mekanik ve termal özellikleri sayesinde endüstriyel polimerlerin taşıdığı özelliklere eşdeğer özelliklerde olup; biyopolimerlerin ilerleyen yıllarda polimer endüstrisinde önemli bir yere sahip olacağı öngörülmektedir. Bu derleme çalışmasında biyopolimerin çeşitleri hakkında bilgiler verilmiş ve sektörlere göre kullanım alanları incelenmiştir.

Sodium alginate and hyaluronic acid are being used extensively in wound care applications for their exceptional properties, including gelation, biocompatibility, exudate absorption, and the ability to provide a moist environment to the wound bed that accelerates healing. This research work presents the potential of developing silver and zinc ions loaded bioactive fibers for wound care applications with improved absorption, swelling (gelling), and antibacterial properties. The effect of loading silver and zinc on alginate/hyaluronic acid biofiber absorption, swelling (gelation), tensile and antibacterial activity were analyzed. It was found that the addition of silver and zinc salts improved the absorption, tensile, and gelation properties of alginate/hyaluronic acid fibers. Zinc-containing fibers exhibited superior properties to silver-containing fibers. The presence of hyaluronic acid influenced the release of silver and zinc ions in various liquid media with a maximum of 26 g/g absorption was observed which suggested the good wound exudate absorption capacity of the developed fibers. The developed fibers showed good antibacterial activity against Staphylococcus aureus and Escherichia coli strains.
