Deep learning and analysis of heavy metal concentration are very crucial to our life, for it plays an essential role in both environmental and human health. In this paper, we developed a new Cu (II) ions sensor made by all organic material with bending and stretching properties. The new sensor consists of chlorophyll-a extracted from fresh leaves of Common Garcinia, plant fiber and with the use of PDMS as a substrate. Fluorescence spectra study shows that chlorophyll-a is significantly much more sensitive to Cu (II) ions than any other heavy metal ions and the device sensitivity outperforms all the Cu (II) ions sensors ever reported. The result fully shows the selectivity of chlorophyll-a toward Cu (II) ions. Bending and stretching tests show that the sensor has an outstanding durability, which can be used to develop accompanying applications, such as real-time sampling and the analysis of Cu (II) concentration specified in athlete’s sweat or patients with brain death and Parkinson’s disease.

具有高灵敏度和可拉伸性的所有有机标签样铜（II）离子荧光膜传感器

深度学习和分析重金属浓度对我们的生活至关重要，因为它在环境和人类健康中都发挥着至关重要的作用。在本文中，我们开发了一种由所有具有弯曲和拉伸特性的有机材料制成的新型Cu（II）离子传感器。新的传感器由从常见藤黄的新鲜叶中提取的叶绿素-a，植物纤维以及使用PDMS作为底物组成。荧光光谱研究表明，叶绿素-a对Cu（II）离子的敏感性比任何其他重金属离子都要高得多，并且该器件的灵敏度优于以往报道的所有Cu（II）离子传感器。结果充分显示了叶绿素-a对Cu（II）离子的选择性。弯曲和拉伸测试表明该传感器具有出色的耐用性，可用于开发配套应用，
