The incidence of food allergies, food sensitivities, and autoimmune reaction is increasing worldwide, particularly among children. Designing a novel device for food testing, researchers have developed a portable, point-of-use technology for rapid, integrated exogenous antigen testing (iEAT). The system consists of a disposable allergen extraction device and an electronic keychain reader for sensing and communication. The extraction kit captures and concentrates food antigens from dispersed food. Captured allergens are then quantified using the miniaturized key-chain reader.
