This research account is an attempt to apprehend the important parameters for synthesizing monodispersed Gold nano rods (GNR) of desired aspect ratios. There is plethora of synthetic strategies for the synthesis of GNR amongst which seed-mediated one is the most celebrated one since it is simpler and is capable of synthesizing GNR of desired aspect ratio. But the biggest hurdle is to standardize all the parameters such as concentration of gold chloride, CTAB, AgNO3 and pH for GNR synthesis and also comprehend the most accentuating and key parameters which affects the most. This is possible only with the help of a Taguchi L9 Orthogonal array design which is a statistical tool to optimize the parameters and also find the percentage effect of each parameter. The S/N ratio which was selected for the synthesis of desired aspect ratio was ‘smaller the better’ which could assist in the synthesis of GNRs of desired aspect ratios. After optimization the most influential parameters for GNR synthesis is found to be 0.5mM Gold, 0.2M CTAB, 5mM Silver nitrate and 3.1 pH.
