Article Abstract

Self-organization is a fundamental process for the construction of complex hierarchically ordered nanostructures, which are widespread in biological systems. However, precise control of size, shape, and surface properties is required for self-organization of nanoparticles. Here, we demonstrate a novel self-organization phenomenon mediated by flexible nanospaces in templates. Inorganic nanoparticles (e.g., silica, zirconia, and titania) are deposited in porous polymer thin films with randomly distributed pores on the surface, leaving a partially filled nanospace in each pore. Heating at temperatures beyond the glass transition temperature of the template leads to self-organization of the inorganic nanoparticles into one-dimensional chainlike networks. The self-organization is mediated by the deformation and fusion of the residual nanospaces, and it can be rationally controlled by sequential heat treatments. These results show that a nanospace, defined by the nonexistence of matter, interacts indirectly with matter and can be used as a component of self-organization systems.

Self-replication of  molecules and microdroplets have been explored as models in prebiotic chemistry. An analogous process for inorganic nanomaterials would involve the autocatalytic nucleation of  nanoparticles-an area that remains largely uncharted. Demonstrating such systems would be both fundamentally intriguing and practically relevant, especially if the resulting particles self-assemble.

The formation of a robust, self-healing hydrogel of a novel pyrene-appended dipeptide, Py-E-A (L-Glutamic acid short as E; L-Alanine short as A) is demonstrated. Detailed studies suggest that nanoscopic fibers with a length of several micrometers have formed by chiral self-organization of Py-E-A gelators. Additionally, live human PBMCs imaging is shown using the Py-E-A fluorophore.

The self-organizable dendron (4-3,4-3,5)12G2X with X = -CO2CH3 and -CH2OH, an already classic dendron, facilitating the formation of a large diversity of columnar hexagonal phases including crystalline, with intracolumnar order, and liquid crystalline, and providing access for the first time to mimics of the transmembrane protein water channel Aquaporin was semifluorinated at eight of the sp hybridized carbons of its alkyl groups to provide (4-3,4-3,5)4F8G2X. The self-organization of (4-3,4-3,5)4F8G2X was analyzed by a combination of oriented fiber intermediate angle X-ray scattering, wide angle X-ray scattering, electron density maps, and reconstructed X-ray diffractograms by emplying molecular models. These experiments demonstrated that fluorophobic effect of (4-3,4-3,5)4F8G2X mediated mostly the helical confiormation of the fluorinated fragments sharper miocrosegregation of the fluorinated fragments in the most ordered states of the resulting 12 helical porous columns.

We have investigated the effect of dye distribution on the electrochemiluminescence (ECL) intensity measured with a simplified magnetic bead-based immunoassay for two families of silica nanoparticles (NPs) doped with the cationic Ru(bpy) and the zwitterionic Ru(bpy)bps complexes (bps = bathophenanthroline disulfonate). The NPs doped with the Ru(bpy)bps complex, which can efficiently self-organize in the NP volume favoring ECL generation, resulted in 150-400% signal enhancement compared to the Ru(bpy)-doped ones.

Physical chemistry aspects are emphasized in this comprehensive review of self-assembly phenomena involving lignin in various forms. Attention to this topic is justified by the very high availability, low cost, and renewable nature of lignin, together with opportunities to manufacture diverse products, for instance, polymers/resins, bioplastics, carbon fibers, bio-asphalt, sunscreen components, hydrophobic layers, and microcapsules. The colloidal lignin material, nanoparticles, and microstructures that can be formed as a result of changes in solvent properties, pH, or other adjustments to a suspending medium have been shown to depend on many factors.
