A self-assembled nine-element optoelectronic tongue consisting of a positively charged water-soluble poly(para-phenyleneethynylene) and three metal ions (Fe , Co , and Cu ) at three different pH values (7, 10, and 13) discriminates all of the 20 natural amino acids in water. Unknown identification was not ideal. Addition of a highly positively charged green fluorescent protein in the presence of Fe , Co , and Cu increased the unknown identification to above 86 %. Linear discriminant analysis (LDA) orders the responses according to the amino acid type, that is, hydrophobic, polar, anionic, or cationic.
一种由带正电荷的水溶性聚对苯撑乙炔和三种金属离子（铁、钴和铜）在三种不同pH值（7、10和13）下自组装而成的九元光电舌，能够区分水中的所有20种天然氨基酸。未知物识别效果并不理想。在铁、钴和铜存在的情况下添加一种带高度正电荷的绿色荧光蛋白，可将未知物识别率提高到86%以上。线性判别分析（LDA）根据氨基酸类型（即疏水、极性、阴离子或阳离子）对响应进行排序。
