Exploring high aspect ratio gold nanotubes as cytosolic agents: structural engineering and uptake into mesothelioma cells - dataset

Here, the controlled synthesis is developed for preparing high‐aspect ratio gold nanotubes (AuNTs) with tailorable wall thickness, microstructure, composition, and optical characteristics. The modulation of optical properties generates AuNTs with strong near infrared absorption.

Surface modification enhances dispersibility of AuNTs in aqueous media and results in low cytotoxicity. The uptake and trafficking of these AuNTs by primary mesothelioma cells demonstrate their accumulation in a perinuclear distribution where they are confined initially in membrane‐bound vesicles from which they ultimately escape to the cytosol. This represents the first study of the cellular interactions of high‐aspect ratio 1D metal nanomaterials and will facilitate the rational design of plasmonic nanoconstructs as cytosolic nanoagents for potential diagnosis and therapeutic applications.
