鸡蛋打破后,帖附在蛋壳上的黏性物质被称为蛋壳膜,虽然总被扔掉,其实却价值巨大。根据2014年9月《生物材料学报》(Acta Biomaterialia)刊发的研究论文,它在工业和医药上有多种用途。扫描电子显微镜下可见超过62种蛋白质构成的薄膜网状结构(如图)。研究者说,这些蛋白质可用于从溶液中沉淀黄金,精细制造铝纳米线生产半导体组件,以及从污水中吸收染料或重金属。通过对蛋壳膜附加化合物,研究者已经制成在人体血液中侦测血糖、多巴胺和尿素浓度的生物传感器。蛋壳膜还可磨
After the egg is broken, the sticky substance attached to the egg shell is called an egg shell membrane. Although it is always thrown away, the value is huge. According to a research paper published in the September 2014 Acta Biomaterialia, it has multiple uses in industry and medicine. Scanning electron microscopy shows more than 62 kinds of protein membrane network structure (Figure). The researchers said these proteins can be used to precipitate gold from solutions, finely fabricate aluminum nanowires for semiconductor components, and absorb dyes or heavy metals from wastewater. By attaching compounds to eggshell membranes, researchers have made biosensors that detect blood glucose, dopamine and urea in human blood. Eggshell film can also be ground
