Silver's Tiny Warriors: A Green Fight Against Bacteria and Embryo Growth

Silver nanoparticles are tiny particles that have big potential in medicine. They are made from silver and have special properties that can fight bacteria. In this case, they were made using a type of algae called Chlorella vulgaris and silver nitrate. The nanoparticles were then tested to see how they affect bacteria and the early growth of chicken embryos. The nanoparticles were studied using different methods. These methods included looking at them under a microscope, measuring how they scatter light, and checking their size and charge. The goal was to understand how they work and how they might be used in medicine. One of the main tests was to see how the nanoparticles affect a type of bacteria called Salmonella enterica. This bacteria can cause food poisoning in people and animals. The nanoparticles were able to stop the growth of the bacteria at certain concentrations. This shows that they have the potential to be used as a treatment for bacterial infections. The nanoparticles were also tested on chicken embryos. This was done to see how they affect early development. The embryos were injected with the nanoparticles and then observed over time. The results showed that the nanoparticles had different effects depending on how long the embryos were exposed to them. After three days, the embryos did not show any significant changes. However, after 16 days, there were noticeable effects. The embryos had lower levels of antioxidants in their blood, changes in their liver enzymes, and alterations in their red blood cells. Some of the embryos even showed signs of hemolysis, which is when red blood cells break down. It is important to note that the effects of the nanoparticles were different depending on what was being tested. The chicken embryos were more sensitive to the nanoparticles than the bacteria. This means that while the nanoparticles can be effective against bacteria, they may also have harmful effects on other living things. This study highlights the potential of silver nanoparticles in medicine. However, it also shows that more research is needed to fully understand their effects. It is crucial to find a balance between their beneficial properties and their potential risks. This way, they can be used effectively and safely in medical treatments.
