Abstract
An aqueous enzyme based sensor comprising one or more enzymes and at least one indicator compound capable of indicating a reaction of at least one of the enzymes with at least one target analyte, wherein the enzyme and the indicator are capable of being delivered, preferably by being sprayed, to a surface having the target analyte without sampling the surface. An aqueous enzyme based sensor is provided that is capable of detecting an enzyme specific substrate as the analyte. This aqueous enzyme based sensor further comprises of one or more enzyme specific substrates in which the sensor detects enzyme inhibition. The aqueous enzyme based sensor optionally comprises one or more of a light scattering additive(s), an adhesive polymer(s), a protein stabilizer(s), a protein stabilizing sugar(s), a surfactant(s), and a solvent(s), and combinations thereof. A dispensing system and a method of detecting a target chemical on a surface without sampling the surface is provided.
