Researchers create method for more sensitive electrochemical sensors
Date:1/17/2013

e magnetic properties of metallic iron while preventing them from oxidation or significant degradation. They were then coated with gold because of its chemical inertness and biocompatibility.

This novel immune-detection platform shows potential for rapid and sensitive screening of environmental pollutants or toxins in samples. Researchers reported the ultrahigh sensitivity of this method for a new generation of herbicide diuron and its analogues up to sub-picomolar concentration in standard water samples. The process also proved to be efficient and cost-effective: tens of thousands of screen-printed electrodes can be manufactured quite readily with low cost for such hybrid assay.
