在高度竞争的水环境中，单个交叉反应共轭聚合物能够产生多维响应，能够识别和区分22种结构相似和生物相关的胺，准确率达到97%。对一组波长的统计分析被用来评估这种方法的可行性。在另一项调查中，使用不同的比率法分析了单一交叉反应聚噻吩的多维反应，以量化鱼基质中存在的生物胺的数量，从而评估食品的质量。
A single cross-reactive conjugated polymer generates a multidimensional response capable of identifying and differentiating between 22 structurally similar and biologically relevant amines with 97% accuracy in a highly competitive aqueous environment. Statistical analysis on an array of wavelengths was used to assess the viability of this approach. In a separate investigation, the multidimensional response from a single cross-responsive poly(thiophene) has been analyzed using a different ratiometric method to quantify the amount of biogenic amine present in a fish matrix, thereby evaluating the quality of the food.
