Gentamycin is a broad-spectrum antibacterial against Gram-positive and Gram-negative bacteria. Gentamycin Sulfate is a white powder that is freely soluble in water and insoluble in alcohol, acetone, chloroform and ether. The study aims to determine the characterization and the biological activity of gentamicin in the Nano-form prepared by Sol-gel application using an ultrasound device by aqueous solution at temperature of 80°. Nano gentamycin examined by Scanning electron microscopy (SEM), transmission (TEM) and the antibacterial effect test of both Nano and stander gentamycin were analyzed. The results showing that the average size of gentamycin nanoparticles is 68.51 nanometers with homogeneous distribution. The antibacterial effect of Nano gentamycin take a wide inhibition range of Gram-positive and Gram-negative bacteria compared to the standard substance, the inhibition diameters are for E. coli (29 mm) and for St. epidermidis (27 mm). In the other side the inhibitory ability for standard gentamicin for St. epidrmidis and E. coli were 18 mm and 20 mm, respectively.
Nanotechnology is a capable approach to enhance the activity of common antimicrobial agent mainly used in human and veterinary drug. Gentamycin is a broad-spectrum antibacterial against Gram-positive and Gram-negative bacteria. The study aims to determine the characterization and the biological activity of gentamicin in the Nano-form prepared by Sol-gel application using an ultrasound device by aqueous solution at temperature (80)0C. Nano gentamycin examined by Scanning electron microscopy (SEM), transmission (TEM), atomic force microscopy (AFM) and antibacterial effect of both Nano and stander gentamycin were analyzed. The results showed that the average size of gentamycin nanoparticles was 68.51 nanometers with homogeneous distribution. The EDX showed large number of elements present in the Nano solution. The antibacterial effect of Nano gentamycin took a wide inhibition range of Gram-positive and Gram-negative bacteria compared to the standard substance, where the inhibition diameter for E.coli was 29 mm, and for St. epidermidis was 27 mm. The MIC of gentamicin nanostructures was the concentration 0.00125 mg/ml.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
