Abstract: Single and multiple layer membranes such as gloves and condoms include one or more deactivating barrier layers and/or indicating layers to indicate to a user membrane breach or the presence of a harmful substance in blood or body fluids. A membrane may include one or more permeable or semipermeable layers to disperse contained substances such as lubricants, biocides, spermicides, or indicators outwardly, and may also include permeable or semipermeable layers to allow transmission of body fluids or other environmental fluids inwardly into contact with an indicating or treating substance. An intermediate layer of a multi-layer membrane may include a substance to wipe, cleanse, sterilize, or otherwise treat a piercing needle. A membrane may include a sealing or coating to entrap indicators or other agents such as biocides therein. A method of making membranes such as gloves results in a double glove having discrete inner or outer layers joined only in a cuff region.
