Abstract AR
تم تحضير دقائق الذهب و الفضة العالقة النانوية باستعمال تقنية الليزر النبضي بقصف هدف معدني بسمك مغمور في الماء المقطر.
تم فحص الحجم و التوزيع الحجمي و الخصائص البصرية للدقائق النانوية باستعمال تحليل مجهر الكتروني ماسح و المطياف على التوالي.
و كذلك تم قياس تركيز الدقائق النانوية باستعمال طيف الامتصاص الذري.
تم دراسة تأثير دقائق الذهب و الفضة النانوية على فعالية إنزيم كاماكلوتاميت الموجود في مصل الدم.
أظهرت دقائق الذهب و الفضة النانوية تأثير تثبيطي على فعالية الإنزيم و زاد هذا التأثير بزيادة الدقائق النانوية.و من دراسة الخواص الحركية للإنزيم أظهرت تأثير تثبيطي من النوع المختلط.
Abstract EN
Laser ablation of metal plate in water was performed in order to obtain gold and silver nanoparticles.
Transmittance electron microscopy TEM and uv-vis spectrophotometer were conducted in order to determine the size and optical properties of the nanoparticles, respectively.
The nanoparticles concentrations were also characterized by atomic absorption spectroscopy AAS measurement.
The absorbance spectra show a sharp and peaks around 400 or 525 nm, indicating the production of silver and gold nanoparticles with average size of 25 nm, have been confirmed by TEM.
Both Gold and silver nanoparticles show inhibition on the Gama glutamate transferase (γ-GT) activity.
The inhibition effect increase as a function of nanoparticles concentrations.
Kinetic properties of (γ-GT) activity revealed (by nanoparticles) mixed type of inhibition.
