Synthesis and surface functionalization of gold microtubes for SERS detection of dyes
Key Points
The aim is to develop gold microtubes for enhanced SERS detection of various dyes.
Synthesis of gold microtubes
Functionalization with 11-mercaptoundecanoic acid (MUA)
Application of SERS to detect methylene blue, methyl violet, and methyl red
Successful detection of multiple dyes using the functionalized gold microtubes through SERS.
Demonstrated enhancement in signal intensity compared to non-functionalized surfaces.
Abstract
Gold microtubes functionalized with 11-mercaptoundecanoic acid (MUA) are used for SERS detection of dyes (methylene blue, methyl violet and methyl red).
