The composition comprises an ester which, when cleaved by esterolytic activity, produces a detectable response such as color formation. In addition the composition comprises the compound 3-quinuclidinol. The device is prepared by incorporating a carrier matrix, such as paper, with the composition. The method comprises contacting a test sample with the device and observing a detectable response.
