surfactantassisted
Surfactant-assisted refers to processes that employ surfactants—surface-active agents—to facilitate a chemical or physical transformation. In these approaches, surfactants influence interfacial tensions, stabilize reactive species, and often template or confine growth to achieve desired structures. The term is widely used in nanomaterials synthesis, colloid science, and materials processing.
Mechanisms commonly involve micelle-templating, where surfactant assemblies act as nanoscale reactors or templates; adsorption on crystallographic
Applications include the synthesis of metal nanoparticles with controlled shapes, such as CTAB-assisted growth of gold
Advantages include improved control over particle size and morphology, enhanced dispersion, and the ability to perform
