Abstract
A device for rapid concentration and detection of live cells in fluids includes a filter to capture a cell sample. The filter includes a first physical barrier with apertures of a first size and a second physical barrier with apertures of a second size smaller than the first size to isolate the cell sample on the filter. Growth detection circuitry associated with the filter electrically measures a cell growth rate associated with the cell sample in less than 2 days. The growth detection circuitry includes a mechanical filter for concentration of cells. The filter and growth detection circuitry are integrally formed within the device, which is sealed.
