In this proceeding, architecting novel magnetic Cross-Linked-Enzyme-Aggregates (CLEA) nanoparticles to effectively and controllably modify textile surfaces without damaging the fabric itself, will be discussed. The efficiency is due to exponentially increased surface concentration of biocatalyst and to the choice of aggregate size which controls the penetration depth and hence preventing the fabric disruption. In addition, due to the presence of magnetic nanoparticles, the continuous recovery and reusability makes this design more economic and ecologic compared to the conventional chemical processes. The careful fabrication and functionalization of such a design with preliminary results will be presented in this contribution.

Tekstilde Çapraz Bağlı Enzim Topluluklarının Kontrollü Yüzey Modifikasyonunda Kullanılması

Öz

Bu makalede, manyetik nano-parçacıkların da içinde bulunduğu, çapraz bağlı enzim topluluklarının (CLEA) oluşturulması ve tekstil işlemede kullanılması fikri ve uygulaması sunulmuştur. CLEA’nın, serbest enzimlere göre daha verimli olmasının iki temel nedeni vardır. Birincisi ayarlanabilen CLEA büyüklüğü ile enzim etkinliğinin kumaşın gözeneklerine girme miktarı sınırlandırılabilir ki bu, kumaşın mukavemetini artırır. İkincisi ise, enzimlerin kumaşın istenmeyen bölümlerine girişini engelleyerek, yalnızca yüzeye yönlendirilmeleri sayesinde yüzey işlenme veriminin arttırılmasıdır. Bunlara ek olarak, CLEA içine yerleştirilmiş manyetik nano-parçacıklar CLEA’nın tekrar tekrar kullanılmasına imkan sunar. Önerilen süreç, alışılagelmiş kimyasal süreçlerle karşılaştırıldığında daha tutumlu ve çevrecidir. İlk CLEA tasarımımız ve uygulamaları, öncül ölçüm sonuçları ile beraber sunulmuştur
