Data for: "Effect of Glycine on Aggregation of Citrate-functionalised Gold Nanoparticles and SERS Measurements"

Raw data for the paper is available as a zip file. Within this file, the main folders contain information about the different samples (namely gold nanoparticle (AuNP) suspensions, glycine aqueous solutions, AuNPs in glycine aqueous solution, and AuNPs in sodium chloride aqueous solution) at different concentrations and different pH values. The different samples were analysed by UV-Vis, Dynamic Light Scattering (DLS) and Surface Enhancement Raman Spectroscopy (SERS) or Raman.

The files are organised first by sample type.
AuNPs
Contains data of the gold nanoparticle suspensions at a concentration of 3.1x10-11 M. The subdirectory structure is as follows:
• pH_XX
o UV-Vis
o DLS
o SERS
The SERS and UV-Vis directories have spectra for a series of acquisition times (Y min).
The UV-Vis data for samples is available as raw spectra data as an Agilent Cary software (.BSW or .DSW) format and Excel data (.xls) format.
SERS spectra data is given in Snowy Range Instrument software as Certificados PKCS #7 (.spc) format or Achivo DLL (.rmn) format and as excel data (.xls) format.
The DLS raw spectra are available as an image file (.jpg and.png) and/or Excel data in (.xls) format.
For example
AuNPs\pH_4.54\SERS\0_min.spc

Glycine
Contains data of concentrations of glycine solutions (0.1, 1, 50 and 100 g/kgH2O) at different pH. The subdirectory structure is as follows:
• YYgkg-1
o pH_XX
- Raman
The Raman directories have spectra for 0 min acquisition time (0 min) in Snowy Range Instrument software as Certificados PKCS #7 (.spc) format and as Excel data (.csv) format.
For example
Glycine\1gkg-1\pH_4\Raman\0_min

Glycine_and_AuNPs: contains data of the mixtures of concentrations of glycine (0.1, 1, 50 and 100g/kgH2O) and gold nanoparticles (3.1 x10- 11M) at different pH.
• YYgkg-1
o pH_XX
- UV-Vis
- DLS
- SERS
For example
Glycine_and_AuNPs\0.1gkg-1\pH_4\UV-Vis\5_min.DSW
Glycine_and_AuNPs\100gkg-1\pH_4\SERS\20_min.RMN

NaCl_and_AuNPs: contains data of the mixtures of concentrations of sodium chloride (1, 10 and 100 mM) and gold nanoparticles (3.1x10-11 M) at different pH. The directory structure is as follows:
• ZZmM
o pH_XX
- UV-Vis
- DLS
- SERS
