但是由于现有的生产方法是通过透射电镜来加工,限制了分子结构的生长与控制,所以很难从基础研究过渡到商业用途。在《科学报告》发表的文章Towards the scale-up of the formation of nanoparticles on α-Ag2WO4 with bactericidal properties by femtosecond laser irradiation 里,西班牙贾米一世大学的Juan Andrés和巴西的圣卡洛斯联邦大学的Elson Longo的团队合作并发现了一个更高效地生产钨酸银的方法。
摘要:In recent years, complex nanocomposites formed by Ag nanoparticles coupled to an α-Ag2WO4 semiconductor network have emerged as promising bactericides, where the semiconductor attracts bacterial agents and Ag nanoparticles neutralize them. However, the production rate of such materials has been limited to transmission electron microscope processing, making it difficult to cross the barrier from basic research to real applications. The interaction between pulsed laser radiation and α-Ag2WO4 has revealed a new processing alternative to scale up the production of the nanocomposite resulting in a 32-fold improvement of bactericidal performance, and at the same time obtaining a new class of spherical AgxWyOz nanoparticles.
