3) Parameters such as solvent, temperature, precursor concentration, surface capping and foreign species can be tweaked to make versatile nanocrystals.  4) Continuous process allow large yields of nanocrystals to be synthesized.  Shape-control in noble metal systems, Ag in particular, is our interest. The structure-property relationship of Ag nanocrystals is evident in their optical properties.   When capabilities in localized surface plasmon resonance (LSPR).  That is when  light incident upon the surface, collective oscillation of free electrons in the nanocrystal arises.   This optical phenomenon is called localized surface plasmon resonance (LSPR).  Under resonance, arises as light wave are trapped within nanocrystals smaller than  the incident wavelength of light \cite{Petryayeva_2011}.  \subsection{Research objective}
