Researchers from Khalifa University develop a new, environmentally friendly method for the production of antibacterial nanoparticles
Silver nanoparticles play an effective role in fighting germs, but the manufacturing process is very expensive and requires toxic solvents to produce.
In this regard, researchers from Khalifa University have come up with a new way to produce silver nanoparticles using biochemistry and magnetic fields, especially since metal and metal oxide nanoparticles are used in a wide variety of commercial applications.
Silver nanoparticles are an example of these metals because of their effectiveness in fighting germs. They are used in soap making, wound treatment, and in the manufacture of some medical ointments and biomedical devices such as catheters and valves that are highly susceptible to bacterial growth.
In this context, a research team from Khalifa University and the University of Carthage developed a new method for producing silver nanoparticles using baking yeast and a static magnetic field. The results of the research were published in the prestigious scientific journal "Scientific Reports" this month.
The research team included Dr. David Sheehan, Professor of Biochemistry and Dean of the College of Arts and Sciences at Khalifa University, and Dr. Siobhan O'Sullivan, Assistant Professor of Molecular Biology and Genetics from Khalifa University also, along with Amini Kathiri, Dr. Salma Hememed, Abdelhak Osmani and Ahmed Landalsi, all from Carthage University. in Tunisia.
Dr. David said: "Our research aims to reduce the use of potentially harmful reagents during the manufacturing process of silver nanoparticles in order to reduce the resulting environmental and health risks."
Dr. David added: “Green chemistry is based on the use of sustainable methods for the design and manufacture of chemicals. Biosystems is one of the most popular methodologies used in the manufacture of green metal nanoparticles, where various types of bacteria, fungi, plants and bio-residues can contribute to catalyzing reactions that lead to metal reduction. to obtain useful nanostructures.
The reduction process is defined as a chemical reaction in which atoms gain electrons from reducing agents, which may be natural or made green from plant extracts or microorganisms to avoid the need for dangerous chemicals.
Green manufacturing is characterized by its effectiveness and appropriate economic cost, in addition to its contribution to the stability of the resulting nanoparticles, and the ability to control the size of the nanoparticle by controlling the quantity and shape of the reducing agent used.
