Gold Nanorods Separation

Sep 07 2018 The goal of the present study was to advance current understanding of the mechanism of separation of rod-like nano-objects in the AF4 channel. To achieve this we have systematically investigated a series of commercially available cetyltrimethylammonium bromide stabilized gold nanorods AuNRs with aspect ratios from 1.7 to 10
