Abstract
The present invention relates to delivering sample preparation technologies to enhance the performance of point-of-care agricultural diagnostics by improving the capacity to detect trace contaminations of pathogenic organisms along the entire food supply chain including pre- and post-harvest processing and distribution. Sample preparation is crucial for adequate test performance of downstream diagnostics like LAMP and supports sensitive detection of bacterial contaminates. This invention increases the speed and scale of routine pathogen surveillance and the efficacy of management response and mitigation of foodborne disease outbreaks.
Claims19
An electroflotation device comprising:
- a cylindrical body having a hollow interior, an upper end, and a lower end;
- a base sealed to the lower end of the body, wherein the base comprises an electrode array exposed to the hollow interior of the body, the electrode array having a concentric outer array and inner array;
- a removable lid connected to the upper end of the body, wherein a hollow core having an open lower end and upper end extends from the lid into the hollow interior of the cylindrical body, such that the hollow core defines an inner space within the hollow core and an outer space between the hollow core and the cylindrical body, and wherein the hollow core extends past a lower rim of the lid for a distance between about 10% and 50% of a height of the body;
- wherein the inner space is in vertical alignment with the inner array and the outer space is in vertical alignment with the outer array;
- and
- a microcontroller.
