A nanoparticle is a small object that behaves as a whole unit in terms of its transport and properties.


Why are nanoparticles useful in producing industrial catalysts?

Silver nanoparticles are used in antibacterial technology embedded in refrigerators, washing machines, air coolers, air conditioners, vacuum cleaners and air purifiers. This helps in blocking transmission of airborne diseases in humans and increases safety of health.


Where can you find colloidal silver?

Most people take colloidal silver to cure infections, boost immunity and prevent colds, flu and other infections. There are 7 things you should know...The type of colloidal silver is more important than the brand.There are three types of colloidal silver: Colloidal silver atoms, ionic colloidal silver and nanoparticle colloidal silver aka colloidal silver.The size of the colloidal silver particle determines how rapidly it is absorbed by the human body.Colloidal silver atoms are individual single atoms and are the smallest particle size attainable, and are more easily absorbed, and expelled, from the human body due to the fact that they do not get trapped in the kidneys or liver, so it's very difficult to get argyria, the blue-gray skin condition so many people fear.Because the atom particles are so small and can penetrate through the outer walls of a virus (which are 300 Nanometers or more in size)make them so much more effective than Ionic or nanoparticle colloidal silver, due to the smaller size of the silver atom.There are many good brands of ionic colloidal silver, colloidal silver, but only a few that offer true atomic particle colloidal silver.While it is argued that the best colloidal silver will have a ratio of 85% ionic silver to 15% colloidal silver., that statement only applied to ionic silver, and ionic silver is comprised of nanoparticles.What is atomic colloidal silver or colloidal silver atoms:Francis S. Key and George Maass, PhD wrote an article in 2001 explaining why nanoparticle colloidal silver is allegedly better than ionic colloidal silver. In this 6 page document they do make a reference to silver atoms and the wrote: "A single silver atom can be considered to be an atomic sized particle of metallic silver. It is the smallest size of silver matter that exists. The diameter of a single silver atom is 0.288 nm. While it is theoretically possible tohave a particle of metallic silver that consists of a single atom, in practice particles are much larger and consist of many atoms. Just for reference, a particle one nanometer in diameter would consist of 31 silver atoms, and a 5 nm diameter particle would be about 3900 atoms while a 20 nm diameter particle would contain about 250,000 silver atoms. The particle size typically observed in colloidal silver has been measured in the range of 5 to 200 nanometers. Such measurements are performed using a Photon Correlation Spectrometer (PCS) that can measure down to 1 nm. In our laboratory a Malvern Zetasizer 3000HS is used to make such measurements."When that article was presented in 2001 colloidal silver atom products were not yet attainable, it was not approximately 2010 when the new technology that actually produced colloidal silver atoms suspended in distilled water was introduced on the open market.Three things to look for in colloids:Chemical CompositionParts Per Million (PPM) ContentParticle Size (the smaller the better).Avoiding chemicals in what you consume is always the best practice, most colloidal silver products contain chemicals. To find out how to detect chemicals in your colloidal silver just do an internet search of "How to Select-Safe-Chemical-Free-Colloidal-Silver".Ionic Colloidal Silver has been reported to contain: phosphates, bromides and or silver protein, aka Chemicals. Traditional nanoparticle colloidal silver has been reported by the FDA to actually contain cyanides, Hydrochloric Acids, Nitric Acids, Sulfuric Acids, Chlorides and peroxides.PPM is extremely important only if you have the smallest particle size achievable, because atoms are not the same as nanoparticles and have been reported to be up to 250 Million times smaller than nanoparticle and Ionic colloidal silver, they will outperform due to the tiny size.Colloidal silver atom theory:If a single nanoparticle can be broken down into individual atoms, then there would be less silver consumed but much more effectiveness because the silver atom would penetrate a virus much more easier than a nanoparticle that would bounce of the viruses instead of penetrating into the virus. So that means:No dangers of contracting ArgyriaNo silver toxicityPure effectiveness due to the rapid penetration of pathogens.*To find the best colloidal silver atoms products, just do an internet search for "colloidal silver 3000 PPM"Why use ionic silver?All forms of colloidal silver may work, some work better than others.What Kind of IonicSilver to avoid?Any that are made with Bromides, phosphates, silver protein due to the side effects of those chemicals.What Kind of regular Nanoparticle Colloidal Silver to Avoid?Any that have a any kind of color (indicates chemicals used).That have Low PPM (anything under 1000 PPM)That say "Do Not Refrigerate or Do not Freeze"That say "Do not expose to Sun or Ultraviolet light"Any that say "Do not apply externally to skin"Any that the label reads: "Colloidal silver...........10 PPM" why?Any that in the Table of Contents Purified Water.Because they are mislabeled, there is no single element called "colloidal silver".While they state that no chemicals are used, Purified Water still contains Salts that are used to create the spark, these salts create Silver Chloride a chemical by product of the combination of Purified Water and Silver Electrodes.Because virtually all of the above have chemicals, they are reluctant to state which chemicals they are using.According to expert congressional testimony, not much silver is needed to be effective especially when atom particle products use less silver, than any other product on the market. Colloidal silver atoms use no chemicals but have a high concentration of atoms PPM.See Sources and related links "Congressional Testimony American Biotech Laboratories"Typical uses of colloidal silver include:Spraying, for lung or nasal infections, by inhaling deeply (use the dosage as directed on labels) Spraying onto cuts, burns, sunburns, sores, cold sores, bandages, frequently. Drops are used (held under the tongue for a minute or so) for internal needs.According to EPA, the daily dose of Ionic and Nanoparticle Silver colloids believed to be safe is 350 mcg of silver daily, for up to 70 years. At this level, one can safely consume seven teaspoons daily of a 10 PPM "colloidal" silver solution. And, a 20 PPM silver solution will have a max daily dose of 3.5 teaspoons.However with Atom Size Particles there are no such requirements due to the fact that:They do not clog the Kidneys or Live, due to the atomic particle sizeThe excreet easily along with other used and waste human tissueAbsolutely zero chemicals are usedThe aotm size particles defy all rules and conditions that nanoparticle and Ionic Colloids haveSo that dosage only applies to low PPM Nanoparticle and Ionic Silver and ALL other chemically made colloids.Atomic Colloidal Silver has no such restrictions because of no chemicals are ever used in the manufacturing process and because comparing apples for apples, there are really not comparable because on one hand you have atoms and on the other you have nanoparticles which can be 250 Million times larger than an atom. So, you should beware of products having 1000 PPM and under of silver with a dose of more than two teaspoons per day.Some products available on the Internet have a concentration in the 100 PPM or more and are made with chemicals. These high concentrations of chemical consumption produce a greater risk of argyria (blue/gray skin) from silver accumulation.As you can see from the list of effective concentrations of silver (the Congressional Testimony) such high amounts of nanoparticle silver are unnecessary, since most microbes die off at well under 10 PPM of silver, however the length of time to achieve this effectiveness can be from weeks to more than 3 months with the Low PPM product, in which you would have to consume a lot of chemicals to get effectiveness.90-99% of nanoparticle silver is removed by the body in two days, according to animal studies. The remainder is removed in the following one to four weeks, so an appropriate break from silver use can prevent the undesirable side-effect of blue/gray skin. That also means that you may allow the virus to build immunity while you take that break.However no such evidence has been introduced in connection with colloidal silver atoms products.The Mayo Clinic has warned that nanoparticle colloids can get lodged in the kidneys, Liver and even skin cells, combined with the chemicals used, they can produce argyria.Not so with Atom size particles which easily get expelled from the body along with the human waste, due to the fact that are much too small and believed to attach themselves to the tiny cell thereby also getting excreting when that host cell is used and no longer needed by the human body.Colloidal Silver Labels:The FDA has issued a report dated 1999, which all the major colloidal silver and ionic silver producers were investigated and studied, they found that they all use chemicals on some form or fashion, their report shows: Ionic Colloidal Silver has been reported to contain: phosphates, bromides and or silver protein, aka Chemicals, traditional nanoparticle colloidal silver has been reported to actually contain cyanides, Hydrochloric Acids, Nitric Acids, Sulfuric Acids, Chlorides and peroxides.Hydroxides, Chlorides and peroxides have been reported to not only cause argyria but may be also responsible for hair loss, premature gray hair, nerve damage, brain cell damage and many other side effects.Many producers of colloids claim not to have chemicals and mislabel their products, because they do not want to show the proof of chemicals to the untrained buyer.According to the BC Canadian government,"Silver is a disinfectant for non-spore forming bacteria at concentrations about 1000 times lower than the levels at which it is toxic to mammalian life." See Sources and related links "Ambient Water Quality Criteria for Silver"According to the US FDA,"Silver has been known for its antimicrobial properties for decades" See Sources and related links "FDA: 'Silver has been known for its antimicrobial properties for decades'.According to Cancer.govDefinition: antimicrobial"A substance that kills microorganisms such as bacteria or mold, or stops them from growing and causing disease."See Sources and related links "Definition: antimicrobial"According to Text Book of Materia Medica and Their Therapeutics by A.S Blumgarten, 6th Edition, M.D., F.A.C.P. printed by The McMillan Company in New York. 1935, the first Edition was written in 1914., proves that silver has been used as early as 1914.Best Hint:To test your colloidal silver for chemicals: Pour your colloidal silver into a clear glass vessal, Freeze the product, let it thaw out, and you will see all the chemicals and nanoparticles drop to the bottom of the glass container. To Test your Ionic Silver for chemicals: You can do the same test above, and or, vigorously Shake the bottle and you will find foam, a clear indicator of chemical use in it manufacture.Look for a brand that says its has atomic size particles, has a high PPM of 3000 or more, completely clear in color, (because the atoms attach themselves to the water molecule no chemicals are ever needed) and is guaranteed not to be made with chemicals.In fact, according to Health Canada (Canada's health dept), if you ate all your fruits and vegetables, everyday, especially mushrooms, you'd probably get more silver in your body than from a daily dose or two of an ionic or nanoparticle colloidal silver.The best brands of colloidal silver typically have a minimum of PPM Ratio of 3000 to 18,000 PPM.To find the best brands, just internet search for "Colloidal Silver 3000 to 18,000 PPM".

What is aggregation of nanoparticles?

Aggrgation of nanoparticles is where they stick together. This is undesirable in nanoparticle solutions, we want each nanoparticle to remain seperate. To combat this differing amounts of salts can be added to stop agglomeration, sodium citrate is one that is used for silver and gold nanoparticles. The zeta potential of the nanoparticle is a masure of its overall charge, ideally we want nanoparticles with a high positive or negative zeta potential as like charges repel each other and will stop nanoparticles from agglomerating.
