Summary:NanoAffix Science has developed a portable handheld tester for quantitative analysis of toxic contaminants, such as lead, in drinking water. Surface functionalized graphene-based nanosensors have unique properties that are very effective for monitoring water quality by measuring changes in conductivity when exposed to very low levels of toxic contaminants. This technology provides very sensitive real time results in minutes on location and can be used to cost-effectively increase the frequency of testing for harmful contaminants. NanoAffix is in the process of taking this new technology to pilot scale and making it commercially available for improving access to potable water.
