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.
Claims20
A method of measuring the presence of a first liquid in a liquid mixture, comprising:
- providing a shape memory polymer substrate including a polymer structure in a programmed state, wherein the polymer structure has a waveform cross-section selected from the group consisting of:
- a square waveform cross-section, a rectangle waveform cross-section, a sine wave waveform cross-section, a triangular waveform cross-section, a sawtooth waveform cross-section, a pyramidal waveform cross-section, and a combination thereof;
- and
- exposing an area of the polymer structure in a programmed state to a liquid mixture, wherein the area of the polymer structure in the programmed state changes the polymer structure to an activated state when exposed to the liquid mixture including the first liquid.
