Objective Synthesis of controlled AuNPs UV-Vis of Red AuNPs/calibration curve with serial dilutions Description The same protocol was followed from Jan. 29th Sodium Citrate used: 0.0044715g Gold used: 0.05031g Stirring at 240 rpm Heated at 155 degrees C, changed to 170 degrees C after one hour 1hr and 20 min in order to reach 90 degrees C, to which the sodium citrate was then added. It was kept on the heat stirring for 5 minutes and 30 seconds. The solution turned a bright red color.
