SILVER APPLICATIONS IN HEALTH
In the past, silver was used in many different health applications, including wound dressings, creams, and antibiotic coatings for medical devices. Silver is also a popular surface coating, and nano-sized silver particles are being developed as biosensors. The uses of silver in health care are vast, and there are countless more to come. In this article, we’ll briefly look at some of the most interesting examples of silver in health care.
Historically, silver was used as an all-purpose remedy for various infections and illnesses
History records numerous uses for silver in medicine, but its medical applications date as far back as the Middle Ages. According to a review of English literature, silver was used to prevent and treat microbial infections for over six millennia. Studies show that silver is highly effective against almost every organism it has been tested against. Other uses for silver include wound healing and the development of radiology.
Researchers have found that silver has the ability to destroy multidrug-resistant bacteria, including M. tuberculosis. It can also inhibit biofouling, and it is effective in preventing chronic upper respiratory tract infections. Silver can even kill M. tuberculosis through the actions of silver nanoparticles in the cytoplasm of the bacteria. But despite its antibacterial effect, silver may not be effective against certain types of bacteria.
Surface coatings incorporating silver are common application
Silver ions have been used to reduce the number of bacteria on surfaces by a factor of 10 in a recent study. The study used surfaces that were treated with silver ions as compared to those that were left untreated. However, further studies are necessary to assess the efficacy of silver in healthcare settings. Surface coatings with silver and other antimicrobial agents can help reduce microbial contamination in healthcare environments.
Silver is a soft transition metal with the highest reflectivity of all metals. It is also biologically active when dispersed into a monoatomic ionic state. In addition, silver is soluble in water and is therefore most effective as an antimicrobial. Silver ionic compounds such as silver nitrate are often used in wound healing. Silver sulfadiazine is a common application of silver-containing coatings in the health care field.
Silver nitrate is a cauterizing agent
Inorganic chemicals such as silver nitrate are commonly used for medical purposes. These compounds have antiseptic properties and have been used for centuries for wound healing and other applications. They are also used as sclerosing agents and astringents. Throughout history, silver has been used to treat a wide range of medical conditions, including infection prevention, ulcer treatment, and halitosis. In ancient times, silver nitrate was injected in newborn infants’ eyes to prevent gonorrhoea, which is usually transmitted from mother to child. However, silver nitrate should not be used on tissues that are capable of regeneration. Eventually, modern antibiotics replaced silver nitrate as a gonorrhoea treatment in eyes.
Today, silver nitrate is used in urology. The substance is injected into the bladder through the urethral canal. This procedure allows the liquid drug to penetrate the entire surface tissue of the bladder. While silver nitrate is a highly effective treatment for many urological conditions, the instillation process is not a standard part of urological guidelines. As with any medical procedure, caution is needed to ensure patient safety and to prevent environmental pollution from contaminating the treatment.
Silver nanowires are being developed into biosensors
Researchers are developing wearable, multifunctional sensors that use silver nanowires to measure physiological parameters. These sensors are similar to electronic transistors but are much smaller, with a diameter about half that of a red blood cell. These sensors can measure multiple stimuli at the same time, including the amount of strain a person is undergoing, the amount of pressure they are experiencing, and even the temperature of a person’s skin. They have many potential applications in medical devices, including prosthetics.
In order to protect silver nanowires, researchers have attempted to create protective shells by coating them with thin polymers, carbon shells, or metal films. These protective shells have increased the durability of silver nanowires but did not provide the uniform smoothness needed for high-precision devices. Researchers have now developed a process that produces ultrathin shells around silver nanowires.
