Nanobiyoteknoloji,
nanobilim ve teknolojide çarpıcı ve en hızlı gelişen alanlardan biridir. Altın
nanopartikülleri (AuNP'ler), yeşil sentez ile herhangi bir yüzey aktif madde,
stabilizatör  ve kimyasal madde
kullanılmadanbıttım(Pistacia terebinthus) yaprak özütü kullanılarak elde edilmiştir.
Elde edilen AuNP’lerin karekterizasyonu UV-vis, SEM-EDX, XRD, FTIR ve TGA-DTA
ile yapıldı. SEM-EDX, analizi incelendiğinde sentezlenen nanomalzemelerin
kristal boyutunun 100 nm’nin altında olduğu ve kristal yapısının küresel olduğu
anlaşılmaktadır. UV-vis, analizi verileri gösterdiki oda koşullarında farklı
zaman aralıklarında yapılan ölçümler sonucunda renk değişimi ile maksimum dalga
boyunun 335 nm’de karesteristik pik verdiği görüldü. XRD analizi verilerinden
kristal yapılarının boyutu 14.37 nm büyüklükte olduğu hesaplandı. Ayrıca
çalışmamızda sentezlenen nanomalzemenin TGA-DTA analizi yapılarak
nanoparçacıkların 1000 oC ‘ye kadar dayanıklı olduğu rapor edildi.
