Uses of Silver
We’ve all heard it said, there are over 10,000 uses of silver in industrial applications. But are there really?
With silver’s unique features of high thermal and electrical conductivity, it will continue to remain king in industrial and electrical applications.
Also, with the recent discovery of nano particles and nano silver, there has been an explosion of silver uses & applications in the home.
This combined with all the silver compounds available such as silver nitrate, silver fluoride, silver bromide, etc… you can easily expand on this list to get into the thousands.
There is hot debate on the safety of nano silver being used in household products, particularly in silver ‘leaking’ into our environment. A recent study suggests this may not be the case.
That being said below are 101 silver uses & applications in everyday life!
Uses of Silver in Medicine & HEALTHCARE
1. Silver sulfadiazine used as a topical cream to treat burns. It made WHO’s list of essential medicines, as an anti-infective medicine.
2. Treatment of warts and corns usually in the form of a caustic pencil. The silver compound silver nitrate, is widely used, and is formed by reacting silver with nitric acid.
3. SilverCoat Foley catheters are used in urology to prevent urinary tract infections from catheter use. Canadian company Covalon is pushing the boundaries on medical technologies that saves lives. This SilverCoat technology is one of them.
4. Use in Radiology, silver halides are still being used in conventional x-ray film as an image receptor. Many third-world countries that don’t have access to advanced technology use this type of x-ray.
5. Silver is used in bandages and dressings to prevent the spread of infection. There is also many uses as gels and ointments for minor scrapes and cuts.
Silver Curad Solution
6. Use in implants and prosthesis. Silver-coated medical prostheses such as knee joints, tibia, femur, etc … are being more and more used to reduce infection rates in patients undergoing surgical implants.
7. Conjunctivitis drops for newborn babies. Silver nitrate has been used for a long time as drops for newborns to prevent pink eye. However, this is slowly being replaced by modern antibiotics such as erythromycin.
8. Prevent cavities with the use of silver diamine fluoride. Kids and cavities go hand in hand, so what better way to prevent that than with a little silver. Reported by DentistryIQ.
9. Silver needles & sutures used by surgeons to close up wounds. This was first discovered in the early 1900’s by a man named Reuben Ottenberg.
10. Silver bearing coatings for hip joint implants named as SMART-HIP. Bearings such as these, not only aid in preventing infection in implants but also reduce friction by silver’s self-lubrication for longer use and durability.
11. Dental fillings are often composed of liquid mercury along with powder mixture of silver, copper, and tin to give it that ‘silver’ look.
12. NASA utilized silver ions as a lightweight water purifier for the Apollo spacecraft. Instead of using traditional chlorine, NASA employed silver ions to be released in the water to destroy bacteria which is later then filtered out. Using a combination of copper and silver ions revealed to be effective in killing E. Coli, Staph, Strep, Salmonella and other common bacteria. The Russians are also known to use silver to purify water in orbit aboard the International Space Station.
13. Hospital tap water filter have been tested with a silver layer membrane to filter and purify the water throughout the hospital. This helps strain microbes and prevent Legionnaire’s disease.
14. Water Purification in third world countries. Colloidal silver is also being used to further treat ceramic water filters to aid in killing bacteria and pathogens & to help bring clean water to developing nations. Junk silver is a great item to have on a survival list for a collapse scenario.
15. Colloidal silver production and use has exploded as a homeopathic remedy and immune builder in recent years to treat ailments and diseases. It can be used to treat bronchial problems, guard against cold and the flu, & treat ear infections to name a few. A popular and recognized brand of Colloidal silver is Sovereign Silver. sovereign colloidal silver
16. Antimicrobial lab coats used by doctors and lab technicians to protect against the growth of microorganisms on your coat. This also fights odor-causing bacteria in its natural state.
17. Cauterizing agent for stomas or openings in surgery. Silver nitrate can be used to close off or remove an opening in the body through cauterization to prevent infections and mitigate damage.
18. Silver nano wire biosensors are being developed for a wide-range of disease diagnostics. The National Science Foundation helped fund a group of UTD faculty in the development of complex electronic bio-sensing mechanisms using silver nano wire.
29. Fight E. Coli. Silver salts added to antibiotics are found to be up to 1,000 times more effective! Silver has the ability to neutralize the bacteria’s defenses making the antibiotic easy to target and kill.
20. Antidote in Mercury poisoning. Silver chloride has been used to treat mercury poisoning by flushing out the toxin from the body.
21. Help stop smoking. I found this one quite interesting, silver acetate in the form of gums, mouth sprays, and lozenges was shown to help people stop smoking. This first hit the market back in the 1970’s with a gum called Tabmint.
22. Surface disinfectant used as a broad spectrum cleaner. The product, Nanosil, is an EPA approved hospital and medical environment disinfectant without the use of toxic chemicals.
23. Kill fungus in the nail bed. Podiatrists are known to use silver in nitrate form to kill off fungus growth in the nail bed.
24. Surgical masks are another product that has been cleared by the FDA for use. Spectrashield surgical respirator masks works with a blend of copper and silver ions woven into the fiber of the mask to eliminate 99.99% certain odor-causing bacteria. Spectrashield
25. Sanitary bed mats with silver containing a non-woven fabric. These mats can be used for long term patients requiring bed stay and help prevent the recurrence of bedsores. Nano silver is hydrophilic which means that when it comes into contact with moisture (sweat, bodily fluids etc …) its anti-bacterial effect becomes stronger!
26. Water, soft drinks, and juice cans are now being targeted with a new kind of colloidal silver by bio tech firm Goldsol. Their product microbisil are extremely small nano particles that are coated with a proprietary substance allowing to remain stable in liquids other than water.
27. Door handles are now being coated with silver to prevent bacteria from spreading. Agion silver is being used and tested on Penn State Erie’s door handles. Moisture from an individual’s hands when touching the door release the silver ions which bind to bacteria killing it off making the handle cleaner. door handle
28. Silver has been tested and used to coat endotracheal tubes to resist the spread of infection and bacteria. Patients on ventilators are at risk to develop pneumonia due to resistant bacteria. Silver coated tubes were found to reduce this form of pneumonia by nearly 40%.
29. Aid in Drug delivery. Silver nano particles are known to increase the efficacy of drug delivery. Researchers at UC Santa Barbara are using silver nano particles coated with a peptide to target & destroy tumor cells. This cutting edge bio technology could soon help in the treatment all sorts of diseases. Adjunct Professor Erikk Ruoslathi, Center of Nanomedicine states:
Silver is a locally used antibacterial agent and our targeting technology may make it possible to use silver nanoparticles in treating infections anywhere in the body

76. Foray stay put pens: pens that are for public use as security counter pens are being coated with anti-microbial solution using silver ions. These high traffic pens are ideal targets for microbial growth.
77. Food garnishing: Yes, that is right! Silver foil just a few micrometers thick, called vark, is sometimes used to garnish delicacies, sweets, and other foods in South Asian cuisine. It’s harmless and edible but has no flavor. This cannot cause argyria which is from the ionic bioactive form of silver, plus the quantity involved is minuscule.
78. Photochromic (tint) lenses: If you wear eye glasses that darken in the sun automatically then most likely you have millions of silver molecules embedded directly into the glass. Silver halides, due to its reversibility to UV rays, are used to make tint lenses. sunglasses
