Abstract
Described are chromogenic sensors, methods of use, and kits including sensors. The sensors can have a polymer structure with a waveform cross-section in a programmed state. Upon exposure to a first liquid, the polymer structure in the programmed state changes to polymer structure in an activated state. Methods for measuring the presence of a liquid using the sensor are described, as are kits including the sensors.
