Dianna has been working to optimize her gold nanoparticle synthesis process using three conditions: acidic (1), basic (2), and neutral (3). The samples all had different visual appearances: the acidic sample being the darkest brown color, the basic sample appearing super concentrated, and the neutral sample appearing yellow/green with some undissolved deposits. Using absorbance, DLS, and NMR, Dianna will get to further analyze these samples and determine where their differences stem from!
