Colloidal Synthesis of Silver Nanoprisms in Aqueous …

Colloidal Silver and hydrogen peroxide, especially in combination, exhibit significant microbial inactivation at concentrations that pose no health risk according to the EEC, WHO and US EPA. Several countries, including Switzerland, Germany and Australia have given approval for the use of colloidal silver and hydrogen peroxide as a drinking water disinfectant. The EEC and Israel Ministry of Health have specifically approved the use of colloidal silver as a drinking water disinfectant at an MCL ). Widespread use might result in potential for uptake of silver ions by humans, but research suggests that: “risks are minimal under all likely scenarios”

This is very important to prepare silver nanoparticles in industry and medical applications.

Moreover, by using PVP as a dispersant, pure, uniform, and stable colloidal silver nanoparticles covered with polymer PVP can be obtained easily in very small size, because the dispersant prevents aggregation of the silver nanoparticles.

If my figures are correct and you cannot produce data to the contrary, then I suggest that you or someone else with the means to do so, conduct appropriate tests to determine accurate comparative concentrations in the blood, urine and feces for ionic, mixed and pure particulate silver, since this remains the only means of definitively proving or disproving Frank's silver chloride hypothesis, already fairly well demolished by the considerable, but patchy evidence already at hand. It is in the interest of all who work with colloidal silver to help settle this matter for once and for all.

What the Experts Say About Colloidal Silver!

I note that Frank's latest experiment is once again conducted in vitro, with no attempt to approach the complexity that exists in the real world, not even the temperature is adjusted. The test medium is free of any organic material, including bacteria and hence is sterile. Under these unnatural conditions it would have been possible to attempt to measure the medium for silver, but instead, a less sensitive measure of weight is used. Is it not conceivable that the contaminants in the HCL and or from dissolved gasses over the 26 hour period could have replaced liberated silver atoms with other elements, making a silver assay more definitive?

Clinical Studies and Reports on Colloidal Silver

Frank is conveniently ignoring the role of aqueous ammonia when simplistically claiming that silver chloride (AgCl) formed on contact of ionic colloidal silver with stomachic hydrochloric acid is insoluble and hence inactive in the body, indeed not assimilated at all. Frank has recently reiterated this claim, stating: "Once silver chloride is formed, which is instantly upon contact, then it is a compound, not dissociated silver ions and chloride ions in solution. So the silver chloride acts as a compound which is insoluble in the blood". I argue(d) that ammonia plays a transmutational role in the chemistry of the biological passage of silver into the body and its utility there.

The US EPA has declared that silver does not cause adverse health effects and has set a Maximum Level at 100 ppb for all drinking water. (9) A new European Union Drinking Water Standard in draft form has removed any upper limit for silver in drinking water following the WHO’s Guidelines for Drinking Water Quality which states that "it is not necessary to recommend any health-based guidelines for silver as it is not hazardous to human health". (9) One teaspoon (5ml) of 1 ppm colloidal silver in a glass (250ml) of water equals 20 ppb. Since the guidelines relate to lifetime exposure for even the most susceptible sub-groups, calculated at 2 litres a day, one could safely consume 8 glasses each with 5 teaspoons (25 ml) of 1 ppm of colloidal silver every day. The most commonly used quantity is a mere teaspoon in a glass of water 3 or 4 times daily.
