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

Anahtar kelimeler
