title: Wettability gradient colorimetric sensing by amphiphilic molecular response.
abstract: Herein we present a highly sensitive sensing method combining amphiphilic molecules and wettability gradient photonic hydrogels for molecular recognition and chemical sensing applications. These wettability gradient photonic films exhibit low analyte amount, fast response, as well as interference resistance, which enable them for applications in forgery detection and visual determination of analyte concentrations.
