文摘
- •
LSPR tuned and carboxylic acid tailed silver nanoparticles was synthesized (Ag@MHA NPs).
- •
Ag@MHA NPs was well characterized by UV–vis and TEM studies.
- •
RRS study revealed aggregated 6cLS heme whereas SERRS study with Ag@MHA NPs exclusively showed 5cHS heme.
- •
Langmuir adsorption isotherm was employed to estimate the real surface coverage of MP-11 on Ag@MHA NPs surfaces.
- •
Ag@MHA NPs showed the Raman enhancement factor 2.36 × 106
