Our modified GNR synthesis protocol, which is intended to produce ultrasmall GNRs, is summarized here.
Notes: The table shows the core ingredients along with stock solution concentrations and the amounts to add to the GNR seed solution and the GNR growth solution. A flow diagram further clarifies the protocol for the synthesis of GNRs. The CTAB-coated GNR art was reprinted by permission from Springer Nature: Light: Science & Applications.
