世界人口当前的环境意识鼓励研究人员研究环境友好的新材料,并能够为所需的应用显示适当的功能。为了发展高性能,廉价的生态材料,科学家经常转向自然,试图以合理的价格模仿其流程的出色性能。在这方面,我们决定专注于藻酸(AA),一种广泛存在于褐藻中的多糖,和曲酸(KA),真菌产生的螯合剂。这项研究提出了快速合成一种可持续的,基于AA和KA的生物相容性材料(AK),使用氯氧酸(CKA)。该材料具有双重功能:对革兰氏阳性和革兰氏阴性细菌的抗菌活性,在体外对人细胞没有任何细胞毒性作用,以及在大气压下将CO2转化为环状碳酸酯的催化能力,没有溶剂,产量高,不使用金属。此外,该材料在有机溶剂中的不溶性使得它可以很容易地从反应产物中分离出来,并重新用于其他催化循环。这两种应用在医疗和环境领域都有关键作用,抗击感染的爆发,并提供一种创新的方法来将二氧化碳固定在特定的基质上。
The current environmental consciousness of the world\'s population encourages researchers to work on new materials that are environmentally benign and able to display the appropriate features for the needed application. To develop high-performing, inexpensive eco-materials, scientists have frequently turned to nature, attempting to mimic its processes\' excellent performance at a reasonable price. In this regard, we decided to focus on alginic acid (AA), a polysaccharide widely found in brown algae, and kojic acid (KA), a chelating agent fungi produces. This study proposes rapidly synthesizing a sustainable, biocompatible material (AK) based on AA and KA, employing chlorokojic acid (CKA). The material has a dual function: antibacterial activity on both Gram-positive and Gram-negative bacteria, without any cytotoxic action on human cells in vitro, and catalytic ability to convert CO2 into cyclic carbonates at atmospheric pressure, without solvents, with high yields, and without the use of metals. Furthermore, the material\'s insolubility in organic solvents allows it to be easily separated from the reaction product and reused for other catalytic cycles. Both applications have a key role in the medical and environmental fields, combating the outbreak of infections and providing an innovative methodology to fix the CO2 on specific substrates.
