“…For example, multilayer ultrathin films are formed through the interaction between two series of gold nanoparticles (PTAA/PVP‐Au) n and (PAA/PVP‐Au) n via hydrogen bonding . Mercaptoundecanoic acid (MUA) functionalized gold nanoparticles could self‐assemble along the poly(ethylene oxide) (PEO) chains through hydrogen bonding between carboxylic groups of MUA and ethereal oxygen atoms of PEO . A monolayer of semiconductor CdSe crystals could assemble on silicon surfaces through hydrogen bonding between thymine‐capped CdSe and Si‐DTA .…”

Studies on the self-assembly of nanoparticles have been a hot topic in nanotechnology for decades and still remain relevant for the present and future due to their tunable collective properties as well as their remarkable applications to a wide range of fields. The novel properties of nanoparticle assemblies arise from their internal interactions and assemblies with the desired architecture key to constructing novel nanodevices. Therefore, a comprehensive understanding of the interparticle forces of nanoparticle self-assemblies is a pre-requisite to the design and control of the assembly processes, so as to fabricate the ideal nanomaterial and nanoproducts. Here, different categories of interparticle forces are classified and discussed according to their origins, behaviors and functions during the assembly processes, and the induced collective properties of the corresponding nanoparticle assemblies. Common interparticle forces, such as van der Waals forces, electrostatic interactions, electromagnetic dipole-dipole interactions, hydrogen bonds, solvophonic interactions, and depletion interactions are discussed in detail. In addition, new categories of assembly principles are summarized and introduced. These are termed template-mediated interactions and shape-complementary interactions. A deep understanding of the interactions inside self-assembled nanoparticles, and a broader perspective for the future synthesis and fabrication of these promising nanomaterials is provided.

“…11-MUA was deposited on the gold surface to facilitate the electrostatic binding between SST and AuNPs (29)(30)(31). Briefly, 1mL of 1mM stock solution of 11-MUA was added to 20mL of the prepared AuNPs solution in a 100mL Erlenmeyer flask.…”

“…Maggos et al measured a significant NO and NO 2 photocatalytic degradation by two types of photocatalytic paints: a mineral silicate paint and a water-based styrene acrylic paint (between 74 and 91% for NO and between 71 and 27% for NO 2 , 6 h of illumination, static mode, in a 30 m 3 chamber) [158]. In this case, the experimental set-up consisted of a flow type reactor adapted from the ISO 22197-1 standard [159]. In a real-scale study, Maggos et al measured a 20% NO x removal by a photocatalytic paint in a car park [160].…”
