Optofluidic SERS in a Microcapillary Coated with a Graphene Oxide/Gold Nanorod Nanocomposite

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate a re-usable microcapillary fiber with a graphene oxide/gold nanorod nanocomposite inner coating for optofluidic SERS. Rhodamine detection is performed with <1sec integration times down to 10−9M in samples of few hundreds of nanoliters.
