Fast Synthesis of Gold Nanotriangles Using Glass Microfluidic Device

A synthesis of gold nanotriangles (GNTs) using glass microfluidic device was reported for the first time in this paper. GNTs can be synthesized by thermal reduction method with cetyltrimethylammonium bromide (CTAB) as capping agent in batch process using glass flask with heating and reflux tube. However, the synthesis in batch process using flask requires long synthesis time of 60 minutes, and total reaction yield of GNTs is about 30%. In this study, a short time synthesis of 0.74 sec comparing with batch process and the reaction yield of 21% were realized using glass microfluidic device.
