Nano Silver Colloid


  1. 99% antimicrobial effect:Effectively kill Staphylococcus aureus, E. Coli, Streptococcus Pneumoniae, Pseudomonas Aeruginosa and Candida Albicans, and also combat H1N1 and Enterovirus.
  2. Long lasting antimicrobial effect:After killing bacteria nanosilver comes back to its original form and still takes effect to rest of bacteria.
  3. Unique antimicrobial mechanism:It kills bacteria quickly and stops their reproducibility, therefore it leaves no drug resistance for next generation.


Silver was long ago discovered to be antibacterial by human. In Roman, ancient Persian time or even earlier people used silverwares to store liquid to avoid putridity. Chinese used silver needle for acupuncture and tested poison by silver hairpin. During First World War European countries took silver as antibacterial agent to avoid infection. All the above are ancient wisdom of making use of silver’s antibacterial effect.
The commonly seen bulk silver is silver grey in color. We have it in nanoparticle colloid in water, presenting amber color, with average particle size between 0.5 to 5 nanometer. This comes with enormous specific area and excellent antimicrobial effect.

Generally speaking a single antibiotic can kill 6 different strains of bacteria, while silver ion(Ag+) can kill 650 types of bacteria instead. Similar to silver ion, Scientists find out that nanosilver is as effective and furthermore the effect lasts much longer without toxicity and adverse side effect. The appropriate employment in applications of nanosilver taking advantage of its strong antimicrobial capability will help increase living environment and personal hygiene to the greatest extent.

By treatment of nanotechnology, Silver particles become small enough to have enormously large surface area. The changed surface structure improves the antibacterial capability by around 200 times. The current most popular theory highlights the unique antimicrobial mechanism to single cell pathogen. When positively charged silver particles encounter the negatively charged microbial cell, they will be drawn together. Cell membrane and wall will be attacked broken and the protein in side cell be modified to be unable to go on normal metabolism and DNA reproduction. Then pathogen will die. It is noted that silver particles staying on the substrate such as filter cloth’s fiber can continue to function to kill all other bacteria without being consumed. Silver particle stays effective after killing a bacterium. This is therefore a long lasting antibacterial material.

Nanosilver skin care lotion

Same function like water spray, however it imparts better retention on the area it applies and the lotion formula further helps the nurturing of skin. Best used on foot, armpit to avoid stinky odor, dried or itchy skin for skin care.


Nanosilver powder as plastic additive

Can be added into plastic to impregnate nanosilver in the plastic products, for example as food container, cutting board, hand grips, push button, plastic armrest, sports items, just to name a few.
