Preparation and characterization of nano magnesium colloid for antibacterial application
The main objective of the present study was to produce nano magnesium colloid via anodization technique. Nano magnesium has a potential to have efficient antibiotic reagents which can prove to be use in wound care and related medical issues. The purpose for this project is to prove the different sizes nano magnesium colloid has difference in efficiency in antibacterial application. Magnesium is to synthesize to produce different sizes of nano magnesium colloid which is then mixed with an unreactive solution to produce a colloid. Then it is tested for its’ antibacterial efficiency. The method will be used to synthesize the magnesium is anodization. Anodization method is a method where by applying an electric field between the anode and cathode in electrolyte which precipitate will be formed at the cathode. Magnesium ribbon and Platinum mesh will be used as anode and cathode respectively. The solution will be Tetrabutylammonium bromide and magnesium acetate mixed with Tetrahydrofuran. The parameters to anodize the magnesium is 1 hour, 2 hours and 3 hours with each time with a variation of 20V, 40V and 60V. Three samples of each anodizing time will be obtained, with a total of 9 samples will be used in the project. After obtaining the different sizes of nano magnesium particles samples they will be dried which will lead to light grey powder that is nano magnesium particles. The samples are then mixed into distilled water to form nano magnesium colloid. Each sample is then put into a zeta sizer to test for the size of nano particle for each sample. Lastly each sample is to be test for its’ antibacterial application by using the adenosine triphosphate test which will reveal the efficiency on which size of nano magnesium particle is best for antibacterial application. It is expected that when the voltage increases the nano particle size also increases and the longer the anodization time the smaller the nano particle size. It will be expected that the magnesium with the anodization of the lowest voltage and longest time will have the best antibacterial properties.
