合成化学品广泛用于食品、农业和医药,因此有必要对环境暴露进行化学品安全评估。此外,化学药物疗效和安全性的快速测定是治疗发现的关键步骤。与动物研究相比,基于细胞的筛选方法是非侵入性的。细胞表型变化也可以提供比常规细胞活力更敏感的化学效应指标。基于阵列的细胞传感器可以被设计成最大化对细胞表型变化的敏感性,降低检测外部刺激下细胞反应的阈值。总体而言,基于阵列的传感可以为基于细胞的化学风险评估和治疗剂发现提供稳健的策略。
Synthetic chemicals are widely used in food, agriculture, and medicine, making chemical safety assessments necessary for environmental exposure. In addition, the rapid determination of chemical drug efficacy and safety is a key step in therapeutic discoveries. Cell-based screening methods are non-invasive as compared with animal studies. Cellular phenotypic changes can also provide more sensitive indicators of chemical effects than conventional cell viability. Array-based cell sensors can be engineered to maximize sensitivity to changes in cell phenotypes, lowering the threshold for detecting cellular responses under external stimuli. Overall, array-based sensing can provide a robust strategy for both cell-based chemical risk assessments and therapeutics discovery.
