Abstract:

Synthesis of silver nanoparticles and Gold nanoparticles using seeds of Nigella sativa and black tea as a capping agents were evaluated in those studies. Different concentrations of the aqueous extract of plants exrtract with silver nitrate solution and Gold salt solutions were exposed to sunlight; as a force for acceleration of the formulation. Then the nanoparticles were characterized by UV-Vis, scanning electron microscope (SEM) and X-ray diffraction (XRD) techniques. Antibacterial activities of the nanoparticles were investigated against Staphylococcus aureus and Escherichia coli as represent the most common types of pathogenic bacteria by the disc diffusion method. The characterization of nanoparticles were detected by the change in color to yellowbrown in silver NPs and pink-purple in Gold NPs which indicated the formulation of nanoparticles and another techniques according to the different in the capping agents in the plants extracts. Different shapes within range of nanoscale were detected using SEM and XRD techniques. The finding suggests that nanoparticles may be effectively used as antibacterial agent as being a future for many fields espically in area of bacterial resistance toward antibiotics.

Biography :

Marvit Osman Widdatallah Omer MSc in PHARMACOLOGY (Pharmacokinetic Specialization) from University of medical sciences and technology (UMST) at 2018. Upheld an outstanding record of academic combined with practical experiences. I completed a bachelor of pharmacy at UMST at 2016, and now am a lecturer at the department of pharmacology and also member in the university research group, interested in researching especially new fields of Nanotechnology and Molecular genetics, beside all of those I got distinction in higher diploma in developmental studies where I believe we need to be in contact for the socities problems to get our researches in the way of helping and make touch. Last year I was completing the registration to Phd programe and now am working through it in pharmacogenetics specializations to identify the relation of different ethnic groups genetically to their impact on the drugs respone. Seven published papers were published throughout my year of experiances in area of pharmacological response of different chemical components either plants exract or the synthetic nanoparticles, nowadays am working in two different review papers beside molecular base research on the mechanism of bacterial resistances toward the antibiotics among a category of Sudanese population.
