Patterning gold nanoparticle using scanning electrochemical microscopy
Patterned arrays of gold nanoparticles (AuNPs) are prepared using scanning electrochemical microscopy by electrochemical reduction of a gold salt at a platinum ultramicroelectrode positioned on top of an unbiased gold surface, modified with a biphenyl dithiol self-assembled monolayer (SAM). The synt...

| Summary: | Patterned arrays of gold nanoparticles (AuNPs) are prepared using scanning electrochemical microscopy by electrochemical reduction of a gold salt at a platinum ultramicroelectrode positioned on top of an unbiased gold surface, modified with a biphenyl dithiol self-assembled monolayer (SAM). The synthesized AuNPs are chemisorbed on the thiolated SAM, and by moving the microelectrode in a lateral direction across the surface while applying a reduction potential, particle-like lines are generated |
