How are the Ag nanotriangles released from the glass substrate into solution after they have been fabricated by NSL?
The Ag nanotriangles are firstly made by NSL on glass slide, then incubated in 1 mM hexandecanethiol (other alkanethiol works as well) for 49-96 h. After incubation, rinse the samples thoroughly with neat ethonal. Lastly, sonicate the samples in ethanol for 3-5 min and you can observe the color on the glass slide is gone.
