Mixed-solvent precipitation: A facile approach for nanoparticle self-assembled monolayers

Mixed-solvent precipitation: substrates were immersed in the good solvent of nanoparticles, then poor solvent were continuously dropped into the mixed-solution, after a few minutes, the Self-Assembled Monolayers (Nano-SAMs) were formed on the substrates via nanoparticles precipitation.

Description
Summary:Mixed-solvent precipitation: substrates were immersed in the good solvent of nanoparticles, then poor solvent were continuously dropped into the mixed-solution, after a few minutes, the Self-Assembled Monolayers (Nano-SAMs) were formed on the substrates via nanoparticles precipitation. [Display omitted] •Nanoparticles rapidly form high-coverage and densely-packed Nano-SAMs via this mixed-solvent precipitation method.•Suitable for multiple nanoparticles, regardless of the size and modification of nanoparticle.•Suitable for multiple ultra-flat substrates, regardless of the surface modification and type of substrate. Nanoparticle self-assembled monolayers (Nano-SAMs) have drawn great attention for their unique applications in many fields such as plasma, surface-enhanced optics, sensors and catalysts. However, how to fabricate high-coverage and densely-packed Nano-SAMs in a limited time is still a challenge, especially for the ultra-thin Nano-SAMs (
