Carboxyl silver nanoparticles are widely used in medical and healthcare applications due to their antimicrobial properties. They are incorporated into wound dressings, bandages, and medical textiles to prevent infections and promote faster healing. These nanoparticles are also utilized in the development of antibacterial coatings for medical devices and implants, reducing the risk of bacterial colonization.

In the field of water treatment, carboxyl silver nanoparticles are employed to purify water by eliminating harmful bacteria and pathogens, making it safe for consumption. They are also integrated into filtration systems to enhance their efficiency in removing contaminants.

Additionally, these nanoparticles play a role in the cosmetics industry, where they are added to skincare products for their antibacterial and anti-inflammatory effects, helping to treat acne and other skin conditions. Their ability to inhibit microbial growth makes them valuable in preserving the shelf life of various personal care products.

In agriculture, carboxyl silver nanoparticles are used to develop antimicrobial agents for protecting crops from bacterial and fungal infections, thereby improving yield and reducing the need for chemical pesticides. They are also explored in food packaging to extend the freshness of perishable items by preventing microbial spoilage.
