Silver and its chemistry have had an enormous impact on society as a whole, both in the realm of healthcare and in the science of photographic film. The use of light-sensitive silver compounds (halides) forms the basis of photographic chemistry. Black & white film and black & white prints have given us permanent records of events as well as photographic art. The effects of light are also relevant to silver’s ability when at nanometre size to absorb visible blue-violet light. When silver absorbs violet light at a wavelength of 420 nm, a strong yellowish tinge is created.
Colloidal Silver (CS), the name given to the substance referred to, has become a ‘buzz word’, yet these so-called colloidal silver particles are in reality not a colloid at all and are not made up of simple particles either. The term silver nanoparticles (known by the abbreviation AgNPs) is not a sufficient description either. Rather than being thought of as dispersed it is better to consider them as in an aqueous electrical suspension. See “What exactly constitutes a high and precise grade of the so-called colloidal silver” on the following pages for more information.
This website emphasises the practice of correct terminology for describing the characteristics of CS, and promotes independent scientific research into what really constitutes this so-called colloidal silver and what it can do for the benefit of mankind. Much will be explained in this website on the true nature of nano silver, which incidentally falls into the realm of Quantum Physics when sized below 10 nm. Research into quantum sized silver is ongoing, and is extending to the design and construction of prototypes of test equipment to enable quality control.
CS has a long history and considerable anecdotes exist as it its antiseptic properties. Historically it was known that a silver dollar placed in milk preserved the milk longer, and using silver utensils improved food-related hygiene, as bacteria do not survive on silver surfaces. The antibacterial actions of silver on bacteria are attributed to the behaviour of its outer electrons. Silver has 47 electrons, an uneven number. The 47th electron is an unpaired electron in the fifth shell and is the most distant from the nucleus of the atom, and so is easily moved away. A similar albeit weaker effect is seen with copper and gold, which have outer unpaired electrons in the fourth and sixth shells, respectively.
The effects of CS on microorganisms are becoming more important as greater attention is placed on the need for alternative agents, with the growing problems of resistance because of excessive use of antibiotics and antifungal agents. Quantum nanometre silver with its many attributes may in the end prove to be a ruthless adversary to antibiotic resistant ‘Super Bugs’.
I am an independent science researcher in the realm of Quantum physics in “nanometer sixed atomic silver clusters in an aqueous electrical suspension”, more popularly known as, ”Nano Colloidal Silver”.
