Latest Patents
One of her latest patents is a colloidal-gold electrosensor measuring device. This invention provides a new device for measuring lead levels in biological and environmental samples. Utilizing square wave coulometry and colloidal gold particles on carbon electrodes, this device offers a rapid, reliable, portable, and inexpensive means of detecting low lead levels. The colloidal gold modified electrodes exhibit microelectrode array characteristics, producing significantly higher stripping detection signals for lead compared to bulk gold electrode surfaces. This method effectively determines lead levels down to at least 5 µg/dL in blood samples as small as 10 µL.
Another significant patent involves convenient determination of trace lead in whole blood and other fluids. This invention relates to methods for determining micromolar levels of lead ion in various fluids, including blood. The methods achieve detection of lead or other heavy metal ion concentrations as low as 1 µg/dL. They are adaptable for detecting low levels of lead in whole blood, employing a novel separation and release of lead ion from lead chelating agents. The disclosed methods utilize isocitrate dehydrogenase-based electrodes, which are particularly suited for detecting nanomolar levels of lead.
