One such idea is colloidal silver, which works but isn't patentable for human consumption because it isn't FDA-approved.
The conference will mainly focus on colloidal and particulate matter in water technology.
Perhaps someday colloidal silver will be widely accepted along with other nontraditional methods of treatment once considered quackery, such as acupuncture.
Colloidal silver is a solution of submicroscopic particles of pure silver suspended in water by an electric charge on each particle.
This would be awfully difficult for naturopaths, whose practices include homeopathy, colloidal silver treatments, and chelation therapy, to name but a few.

Colloidal suspensions contain particles of one material (a solid or a liquid) dispersed in another (which can be solid, liquid or gaseous).

Composed of light-absorbing, colloidal quantum dots linked to carbon-based fullerene nanoparticles, these tiny two-particle systems can convert light to electricity in a precisely controlled way.

These new techniques give scientists and engineers the tools to explore the role of colloidal and small particulate material in natural waters and in water treatment processes.
Anything that can be made colloidal (for example polymers, semiconductors or even metals) could, Dr Lewis reckons, be deposited with sufficient precision to be incorporated into a composite.

Three main topics will be tackled, namely removal of particulate and colloidal matter within drinking water production and in wastewater treatment, and reduction of colloidal carriers mobilised from waste disposals.
Aquatic colloid science and engineering is currently undergoing a period of rapid development, driven by the emergence of a range of new and complementary techniques for the separation, fractionation and characterisation of colloidal material.
It aims to establish a platform for exchange of knowledge with respect to methods for characterisation of colloidal and particulate matter in these systems and to cover the technological aspects of particulate matter in different water treatment processes such as drinking water, wastewater and landfill polluted waters.
