Eggshells, the non-edible part of an egg, have immense uses in nanotechnology. Copper being an inexpensive metal has versatile applications in nanotechnology. However, its susceptibility to oxidation limits its practical applications. Eggshells are an efficient candidate to synthesize cap copper nanoparticles and copper nanoclusters, which are used in various arenas (dye degradation, antibacterial activity, nitrophenol adsorption, copper adsorption, and sensing). Reports on the edible part of an egg for passivating copper nanoparticles are rare. Usually, chicken eggshells are mostly used in this regard. Moreover, eggshells can be used for the adsorption of ionic copper. Thus, the synergism between eggshells and copper is a very pivotal aspect. The use of biological waste in association with copper in various applications may open a new pathway towards the circular economy. This review article summarizes applications that evolved from copper-eggshell synergism.
蛋壳是鸡蛋不可食用的部分，在纳米技术中有广泛用途。铜作为一种廉价金属，在纳米技术中有多种应用。然而，其易氧化的特性限制了其实际应用。蛋壳是合成帽状铜纳米颗粒和铜纳米团簇的有效候选材料，这些材料用于各种领域（染料降解、抗菌活性、硝基苯酚吸附、铜吸附和传感）。关于鸡蛋可食用部分用于钝化铜纳米颗粒的报道很少。通常，在这方面大多使用鸡蛋壳。此外，蛋壳可用于吸附离子铜。因此，蛋壳与铜之间的协同作用是一个非常关键的方面。在各种应用中将生物废弃物与铜结合使用可能会为循环经济开辟一条新途径。这篇综述文章总结了由铜 - 蛋壳协同作用发展而来的应用。
