SUMMARY
The discussion centers on the comparison of ligand charge density between PEG-COOH and PEG-OH for Au-citrate nanoparticles. Participants conclude that PEG-COOH exhibits a higher anionic charge density due to the greater acidity of carboxylic acid compared to alcohol. Additionally, considerations such as pH and the molecular weight of PEG are crucial for successful phase transfer of citrate-capped nanoparticles.
