Biosensor chip, computer illustration. Biosensors are able to detect minute molecules to help monitor a person's health and their environment. Scientists are developing sensors that are sensitive enough to detect even the smallest presence of molecules, so that disease or dangerous environmental contaminants can quickly be assessed. This device consists of a tiny glass slide of sliver with protein receptors applied to it. When the receptors bind with their matching signal molecule, light waves traveling across the chip are perturbed into a recognisable interference pattern. Using this combination of light waves and biomolecules has resulted in a biochip a magnitude more sensitive than other current comparable sensors.
