Comparison of Raman-active quality of studied surfaces in terms of SERS findings.
| Surface | SERS findings and related comment |
|---|---|
| AgNS | · Second least background noise
· Second most efficient results · More identifiable peaks with higher intensities compared AuNP/Nanocellulose, TLC and aniline |
| AuNRs | · Third least background noise
· The most efficient results · More identifiable peaks in higher intensities compared to all |
| AuNPs/nanocellulose | · The least background noise
· The intensity of main band (627 s-1) was significantly lower compared to AgNRs and AuNRs |
| TLC | · Lower number of identifiable bands with extremely low intensities
· Useless in SERS-based detection and quantification of MM* |
| AuNPs/polyaniline | · The most background noise.· The least number of identifiable peaks
· Useless in SERS-based detection and quantification of MM*. |
