Günümüzde nanofiber komponenler (poliakrilonitril dimetil formamit gibi)bir çok mühendislik alanında ve gıda sektöründe kullanılmaktadır. Çevre vehedef olmayan organizmalar üzerindeki muhtemel etkilerin belirlenmesigerekmektedir. Drosophila melanogasterMeigen (Diptera: Drosophilidae) gelişim biyolojisi ve çevre çalışmalarında çokçalışılan model bir organizmadır. Bu çalışmada, erginler nanofiber(elektrospinle üretilen 260 nm çap aralığına sahip PAN-DMF) kaplı diyetlebeslenerek yetiştirilmiş, ergin evreye kadar biyolojik özellikler gözlenmiştir.Nano fiberin etkisi ile D. melanogaster'in yaşama gelişme ve hayattakalma oranları araştırılmıştır. Besin yüzeyi ve canlılık SEM kullanarakgörüntülenmiştir. Elde edilen sonuçlara göre, PAN-DMF kontrollekarşılaştırıldığında besin yüzeyinin uygun olduğu görülmüş; ve böceğin gelişimsürecini kötü etkilemediği bulunmuştur. Besinle ilişkili organizmalardananofiberler kullanılabilir, fakat bu bileşenlerin çevre ve hedef olmayanorganizmalar üzerindeki etkilerinin anlaşılabilmesi için çok detaylıçalışmalara gerek duyulmaktadır.

Today nanofiber components (polyacrylonitrile dimethylformamide etc.) are used in many engineering fields and food industry. Possibleeffects are need to be identified on the environment and non-target organisms. Drosophila melanogaster Meigen (Diptera:Drosophilidae) hasbeen one of the most studied organisms, working as a model in developmentalbiology and environmental studies. In this study, adults were fed withnanofiber coated diet (PAN-DMF; produced by the electrospinning, range ofdiamer 260 nm), eggs were obtained from adults, and biological traits wereobserved until the adult stage. The effect of nanofiber on survivorship anddevelopment ratio of D.melanogasterwere investigated. Nutrient surface and viability werevisualized by using SEM. According to the obtained results, PAN-DMF is suitedwith the nutrient surface compared to controls; and was found to have noadverse effect on the development of insect. Nanofibers can be used in foodcontact organisms, but more detailed studies would be needed to understand theeffects of these components on environment and non target organisms.
