“…A FT-IR analysis was performed to analyze the chemical structure of the organic-inorganic hybrid particles synthesized by a simple mixing and drying process. Commonly, organic-inorganic hybrid particles have been prepared by a chemical bonding method using the electrostatic charge interactions between different particles [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. However, the chemical bonding method requires a complex and long synthetic procedure.…”

Functional light scattering materials have received considerable attention in various fields including cosmetics and optics. However, a conventional approach based on optically active inorganic materials requires considerable synthetic effort and complicated dispersion processes for special refractive materials. Here, we report a simple and effective fabrication strategy for highly scattering hierarchical porous polymer microspheres with a high-refractive index inorganic surface that mitigates the disadvantages of inorganic materials, producing organic-inorganic hybrid particles with an excellent soft-focus effect. Hierarchical organic-inorganic hybrid particles were synthesized using the simple physical mixing of porous poly (methyl methacrylate) (PMMA) microparticles with different pore sizes and regularities as the organic core and titanium dioxide (TiO2) nanoparticles with different particle sizes as the inorganic shell. The polar noncovalent interactions between polar PMMA microspheres and the polar surface of TiO2 nanoparticles could induce the hierarchical core-shell structure of hybrid particles. The synthesized hybrid particles had increased diffuse reflectance properties of up to 160% compared with single inorganic particles. In addition, the light scattering efficiency and soft-focus effect could be increased further, depending on the size of the TiO2 nanoparticles and the pore characteristics of the PMMA microspheres. The proposed study can provide a facile and versatile way to improve the light scattering performance for potential cosmetics.

“…Caused by specific particle-surface interactions, ordering of metal nanoparticles and formation of specific geometrical arrangements/patterns has been observed in a variety of nanoscale materials [14][15][16][17][18][19][20] . However, it is difficult to isolate such unique structural arrangements in a stable form for collection of datasets.…”

A unique ordering effect has been observed in functional catalytic nanoscale materials. Instead of randomly arranged binding to the catalyst surface, metal nanoparticles show spatially ordered behavior resulting in formation of geometrical patterns. Understanding of such nanoscale materials and analysis of corresponding microscopy images will never be comprehensive without appropriate reference datasets. Here we describe the first dataset of electron microscopy images comprising individual nanoparticles which undergo ordering on a surface towards the formation of geometrical patterns. The dataset developed in this study spans three levels of nanoscale organization: (i) individual nanoparticles (1-5 nm) and arrays of nanoparticles (5-20 nm), (ii) ordering effects (20-200 nm) and (iii) complex patterns (from nm to μm scales). The described dataset for the first time provides a possibility for the development of machine learning algorithms to study the unique phenomena of nanoparticles ordering and hierarchical organization.

“…Altogether, these hybrid nanostructures are brought together by specific interactions that result in the synergistic enhancement of their functional properties. 72 A study conducted by Tingting Xu et al depicted that organic-inorganic hybrid nanocomposites based on chitosan derivatives (chitosan-glutathione, chitosan-glutathione-valine and chitosan-glutathione-valine-valine) and layered double hydroxides (LDH) were successfully able to target peptide transporter-1 on the corneal epithelial cells in rabbits. These nanocomposites exhibited prolonged pre-corneal retention, superior corneal permeability and enhanced ocular bioavailability of the model drug pirenoxine sodium.…”
