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
A device for processing fluids includes a filter to capture a cell sample. The filter has a physical barrier to isolate the cell sample on the filter. Growth detection circuitry is associated with the filter. The growth detection circuitry identifies, through electrical measurements, a
