Samples were then coated with a thin carbon layer (1 carbon string) using a Balzers MED 020 (Liechtenstein). The carbon layer technique allows detection of colloidal goldparticleson bacterial and cellular surfaces without charging problems of the samples
你好,谢谢回复,我之前去过一个高校喷碳,那里使用铅笔芯做材料喷的碳,之后扫描电镜无法看到胶体金颗粒,怀疑是铅笔芯的碳颗粒比我的胶体金颗粒大(10纳米),所以想知道文献中carbon layer (1 carbon string) using a Balzers MED 020,指的是什么材料,头疼啊,帮帮忙啊
