Abstract

In addition to the series of articles related to metallic nanoparticles applied to plasmonics, the aim of this review is to discuss the main factors that influence the process of obtaining this type of material. Thus, the article is divided into two main parts: 1) Mechanism, in which a general idea is given regarding the evolution of the concepts involved in the steps of nucleation and growth of metallic nanoparticles, as well as a discussion on the parameters that favor the control of the reaction by kinetics or thermodynamics. Additionally, the main strategies used for composition and shape control, also a brief explanation about the surface of the obtained products are presented. 2) Synthesis, in this section, the main methodologies for obtaining metallic nanoparticles on a laboratory scale are demonstrated, namely those in batch and by electrochemical routes, in addition to the discussion on flow methods, which is believed to be the most effective and viable strategy for obtaining nanoparticles on a large scale.
