We demonstrate that one-dimensional indium tin oxide nanorods (ITO NRs) with high tin-incorporation ratio can be readily produced with a very good control over size and morphology using a gas-phase synthetic approach. Our current study presents a straightforward and facile growth route to synthesize ITO NRs with the atomic composition ratio of In:Sn:O (1:1:2). We further identified and assessed a promising potential application of these tin-rich InSnO2 NRs in biomolecular fluorescence assays. As-grown InSnO2 NRs showed a promising result for potential application in the fluorescence detection of protein molecules.
