Manipulating the solubility of gold nanoparticles reversibly and preparation of water-soluble sphere nanostructure through micellar-like solubilization

Article Abstract:

A strategy tuning the solubility of gold nanoparticles reversibly is developed based on micellar solubilization. The results have shown that hydrophobic octadecylamine (ODA-gold) and hydrophilic poly(vinylpyrrolidone) (PVP)-ODA-gold nanoparticles can be transformed reversibly by using ODA-gold as the initial material through adsorption and desorption of PVP molecules on ODA-gold nanoparticles.

Electrochemically partitioned assembly of organosulfur monolayers and nanoparticles

Article Abstract:

Partitionally assembled organosulfur monolayers are prepared by using an electrochemically assisted assembly method on gold films that are preseparated into two regions insulated from each other. The partitionally assembled sulfur-based monolayers with different terminal groups are used to form location-selective nanoparticle assemblies.
