Described is the application of layer-by-layer electrostatic assembly techniques to electrospun nanofibers in order to fabricate novel, breathable electrospun fiber-based chemical and biological detoxifying protective fabrics and filters. The cartridge is adapted to perform an assay on the blood sample and to produce an indication of an assay result entirely within the cartridge. The storage processors then may communicate among themselves to synchronize a distributed mirror. The present invention also provides a system in which it is not necessary to know precise wavelengths of LEDs where precise wavelengths were needed in the past.
