Description

Application

Dodecylethyldimethylammonium bromide (C₁₂EDMAB) can be used:

As a growth-directing surfactant in the synthesis of monodisperse gold nanorods.
As a surfactant in the synthesis of poly(methyl methacrylate)-poly(N-isopropylacrylamide) core-shell particles via emulsion polymerization.
As an additive in the synthesis of mesoporous nanocrystalline TiO₂ microspheres to increasing the degree of crystallization and modification in the texture of TiO₂.

Gold nanoparticles having a rod-like morphology are regularly investigated as potential nano-therapeutic materials owing to their interesting optical properties, facile surface modification, tunable aspect ratios, and low cytotoxicity. Gold nanorods are historically prepared starting from HAuCl4 in the presence of
