Coated Chiral Plasmonic Nanorods with Enhanced Structural Stability

Several synthesis techniques have emerged for the preparation of chiral metal nanoparticles (NPs) with intrinsic geometrical structures and high optical activity. Chiral plasmonic NPs typically display intricate morphologies terminated by high-energy facets, resulting in limited long-term thermal stability, which is critical development their applications, e.g., biomedical field. gold nanorods (Au NRs) suffer from loss structural stability (reshaping), turn results We carried out a systematic analysis Au NRs covered different protecting shells, against corrosive ions reshaping. Our findings can be readily extended to other fine details alleviate concerns instability various applications under heating complex environments.
