![]() Silver, used as a topical antiseptic, is incorporated by bacteria it kills. The antibacterial action of electrodes coated with silver nanostructures is greatly improved in the presence of an electric field. Applying an electric current across silver electrodes enhances antibiotic action at the anode, likely due to the release of silver into the bacterial culture. The antibacterial action of silver has long been known to be enhanced by the presence of an electric field. ) to irreversibly damage key enzyme systems in the cell membranes of pathogens. The effectiveness of silver compounds as an antiseptic is based on the ability of the biologically active silver ion ( Ag + The antibacterial action of silver is dependent on the silver ion. Silver and most silver compounds have an oligodynamic effect and are toxic for bacteria, algae, and fungi in vitro. Alternative medicine products such as colloidal silver are not safe or effective. ![]() Silver generally has low toxicity, and minimal risk is expected when silver is used in approved medical applications. ![]() There is tentative evidence that using silver-alloy indwelling catheters for short-term catheterizing will reduce the risk of catheter-acquired urinary tract infections. The limited evidence available shows that silver coatings on endotracheal breathing tubes may reduce the incidence of ventilator-associated pneumonia. Wound dressings containing silver sulfadiazine or silver nanomaterials may be used to treat external infections. The medical uses of silver include its use in wound dressings, creams, and as an antibiotic coating on medical devices.
