Abstract
Described is a device comprising a quorum sensor array and a method of using such a device. Also described are methods for calibrating a camera for microstructures.
Claims33
A device comprising:
- a substrate, and
- a quorum sensor array on the substrate,
- wherein the quorum sensor array comprises quorum sensors that release signal molecules in response to one or more environmental signals being sense by the quorum sensors to thereby amplify the one or more environmental signals by causing a signal chain reaction in neighboring quorum sensors of the quorum sensor array, and wherein each of the quorum sensors comprises a lipid multilayer structure.
A method comprising the following steps:
- (a) providing data for changes in optical properties of at least part of a quorum sensor array in response to exposing the quorum sensor array to one or more environmental signals, and
- (b) determining the presence of the one or more environmental signals based on the data of step (a),
- wherein the quorum sensor array comprises quorum sensors that release signal molecules in response to the one or more environmental signals interacting the quorum sensors to thereby amplify the one or more environmental signals by causing a signal chain reaction in neighboring quorum sensors of the quorum sensor array, and wherein each of the quorum sensors comprise a lipid multilayer structure.
A method comprising the following steps:
- (a) calibrating a camera based on a calibration profile,
- (b) detecting with the calibrated camera one or more light intensities of light scattered by one or more iridescent microstructures of a sample, and
- (c) determining a height of each of one or more iridescent microstructures of the sample based on the one or more light intensities detected in step (b),
- wherein the calibration profile is based on the one or more light intensities detected by the camera for light scattered by one or more patterned arrays of standard iridescent microstructures of a calibration standard, and
- wherein each of the patterned arrays of standard iridescent microstructures comprises iridescent microstructures having the same shape and two or more different heights.

- (b) determining a height of each of the one or more iridescent microstructures of the sample based on one or more light intensities detected in step (a) and a calibration profile for the camera,
- wherein the calibration profile is based on light intensities detected by the camera for light scattered one or more patterned arrays of standard iridescent microstructures of a calibration standard, and
- wherein each of the patterned arrays of iridescent microstructures comprises iridescent microstructures having the same shape and two or more different heights.
