    Abstract: The present disclosure provides a monitoring device comprising a test composition, a test element comprising a test portion to which the test composition is releasably adhered, a detection reagent, and a container comprising a first end with an opening and a second end opposite the first end. The test composition comprises a predetermined quantity of tracer analyte. The container is configured to receive the test portion and configured to be operationally coupled to an analytical instrument. The tracer analyte and the detection reagent each are capable of participating in one or more chemical reaction that results in the formation of a detectable product. A method of using the monitoring device to assess the efficacy of a washing process is also provided.

    Abstract: Porous devices are provided that include a particle-containing fibrous porous matrix and a fluid absorbed in the particle-containing porous fibrous nonwoven matrix. The particle-containing fibrous porous matrix includes a porous fibrous nonwoven matrix containing first polyolefin fibers, second polyolefin fibers including poly(ethylene), and fiberglass fibers; and microorganism-binding particles. The microorganism-binding particles are enmeshed in said porous fibrous nonwoven matrix. Methods of debridement are provided including providing a porous device including a particle-containing fibrous porous matrix and wiping a wound or an area of skin with the device; and providing a porous device including a porous fibrous nonwoven matrix and wiping a wound with the device. Further, kits are provided including a sterile package containing at least one porous device, and typically also instructions for debridement.
