4-Thiobenzoic acid-functionalized nanocomposite probes for surface-enhanced raman spectroscopy-based detection of CA19-9 in colorectal adenocarcinoma
This study presents a novel surface-enhanced Raman spectroscopy (SERS) method for detecting CA19–9 in colorectal adenocarcinoma using 4-thiobenzoic acid (4-TBA) functionalized gold nanoparticles (nanospheres). The optimized SERS probes exhibited a maximum enhancement at pH 7 and 50 μM 4-TBA concentr...
