title: An array sensor consisting of a single indicator with multiple concentrations and its application in ion discrimination.
abstract: Optical sensor arrays typically require a large set of chemically responsive colorants to enhance discrimination capability. Conversely, we have proven that by using multiple concentrations of one indicator, the discrimination of various analytes could be realized.
