A new cold nanowelding technique for cetyltrimethylammonium bromide (CTAB)‐stabilized colloidal nanorods in water is reported. This technique leads to the formation of micrometric nanowires by end‐to‐end self‐organization and welding of nanorods. This cold welding strategy could be generally applicable to colloidal nanoparticles and opens new outlooks for the bottom‐up fabrication of nanodevices using colloidal building blocks.
