Hollow and porous gold nanoshells with high surface-enhanced Raman scattering efficiency have been fabricated through utilizing nanosecond laser irradiation.
Gold nanotriangles (AuNTs) were used as a modifier on the surface of a carbon ionic liquid electrode (CILE), which was applied to realize direct electrochemistry and electrocatalysis of horseradish peroxidase (HRP).
We demonstrate the detailed effects of laser wavelengths and nanoparticle surface conditions, as well as laser fluences, in the structural modification of porous gold nanoshells induced by picosecond pulse irradiation.
