Abstract :

This study aims to determine the best concentration of Nanogold and the effect of Nanogold-Nanosilver injection on increasing the immune system of people affected by Covid-19. The method used is quantitative and quantitative descriptive by observing the progress of giving injections once a month (May – November 2021) regarding the complaints experienced. The best concentration of Nanogold for injection observed on the antioxidant activity and λ maximum stability of Nanogold solution 5, 10, 15, 20, 25, 30 ppm after synthesis and after being stored for 7 days using UV-Vis Spectrophotometry instruments. Produce antioxidant activity 44,21%; 47,88%; 51,37%; 52,32%; 56,16%; 61,57%, with an IC50 of 14 ppm and a λ maximum stability of 5 – 20 ppm is stable; 25 – 30 ppm shifted by 0,50 nm. So, the best concentration of Nanogold was 20 ppm which was then characterized using the TEM instrument, resulting in an average size of 22,67 nm. A mixture of Nanogold-Nanosilver was injected into the respondents and obtained interview data after each injection. Respondents acknowledged that there was a significant difference, as evidenced by the percentage of development of body condition getting better. Thus, Nanogold and Nanosilver materials can increase immunity during the Covid-19 pandemic.
