Abstract

Quick and robust analytical methods are of vital necessity in medicine and biology, making the synthesis of electroactive substrates for the sensing of medically relevant chemicals, a promising area of material science. Rare-earth cuprates, mostly famous for high-temperature superconductivity, continue to exhibit encouraging electroactivity towards surface selective oxidation of biologically active compounds. Samarium cuprate reported in this paper showed developed surface with unique porous morphology and good conductivity––a set of prerequisites for the sensing material. Further studies confirmed excellent samarium cuprate-based carbon paste-electrode sensitivity of enalapril maleate and helped to develop an analytical method with selectivity and stability applicable for wider use.

Graphical abstract

Sintering of equimolar amounts of copper and samarium oxides provides crystalline samarium cuprate at the temperature below its melting point. Obtained material has developed surface with micron-size pores. Further electrochemical studies as an additive in carbon paste, confirmed its excellent activity towards hypertension drug sensing.

具有微米孔径的铜酸钐用于药物传感

快速和强大的分析方法在医学和生物学中是至关重要的，这使得合成用于医学相关化学物质传感的电活性底物成为材料科学的一个有前途的领域。稀土铜酸盐，主要以高温超导性而闻名，在生物活性化合物的表面选择性氧化方面继续表现出令人鼓舞的电活性。本文报道的铜酸钐表面发育，具有独特的多孔形态和良好的导电性，这是制备传感材料的先决条件。进一步的研究证实了铜钐基碳糊电极对马来酸依那普利具有良好的灵敏度，并有助于开发一种选择性和稳定性高、可广泛应用的分析方法。等摩尔量的铜和钐氧化物在低于其熔点的温度下烧结得到结晶的铜钐。所得材料表面发育有微米大小的孔隙。进一步的电化学研究证实了其作为碳糊添加剂对高血压药物传感的良好活性。（注：请在期刊网站http://www.ias.ac.in/chemsci/index.html的“投稿信息”下查看更多图形摘要示例。）

期刊介绍： Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
