The identification of infant formula is important for the health of newborns and economic concerns. Here, we present the construction of a three-unit fluorescent sensor array for the discrimination of powdered infant formulas according to species, country of origin, and brand. The array consisted of the conjugated polymers PPE2, PPE-SO3, and PPE-N1, which generate nonspecific interactions with substances in infant formulas and produce response signals. A multivariate statistical analysis was performed using LDA to recognize the response patterns. Leave-one-out cross-validation and LDA classifier showed the successful discrimination of 24 different infant formula samples according to their species, countries of origin, and brands. This sensor array does not require any sample pre-/post-treatment. Its speed and efficacy of discrimination is comparable or superior to existing discrimination methods for infant formula.

使用荧光传感器阵列根据物种、原产国和品牌区分婴儿配方粉

婴儿配方奶粉的识别对于新生儿的健康和经济问题很重要。在这里，我们展示了一种三单元荧光传感器阵列的构建，用于根据物种、原产国和品牌区分婴儿配方奶粉。该阵列由共轭聚合物 PPE2、PPE-SO3 和 PPE-N1 组成，它们与婴儿配方奶粉中的物质产生非特异性相互作用并产生响应信号。使用 LDA 进行多变量统计分析以识别响应模式。留一法交叉验证和 LDA 分类器显示成功区分了 24 种不同婴儿配方奶粉样品，根据其种类、原产国和品牌。该传感器阵列不需要任何样品前/后处理。
