Summary: The assembly of colloidal particles into superstructures is significant for understanding collective behavior and designing novel colloidal materials. Light plays a crucial role in the directed assembly process, and the understanding of light-matter interaction is critical for tailoring assembly kinetics. Colloidal atoms exhibit diversity in size, shape, and composition, enriching the geometric complexity of colloidal matter. The emerging applications of colloidal superstructures in nanophotonics, nanocatalysis, and nanomedicine are discussed.

Summary: This study describes the reversible self-assembly of plasmonic nanoparticles capped with complementary copolymer ligands into colloidal molecules via halogen bonding interactions. The coordination number of the colloidal molecules is determined by the number ratio of complementary halogen groups on the interacting nanoparticles. The reversibility of the halogen bonds allows for controlling the formation and disassociation of the colloidal molecules and their optical properties. The engineered reversible nanostructures may have applications in sensing, catalysis, and optoelectronic devices.

Summary: Periodic superlattices of noble metal nanoparticles with well-defined strong hotspots are achieved by a chemically driven, templated self-assembly process. This technology allows for the assembly of nanoparticles with various shapes, resulting in homogeneous nanoparticle clusters on a centimeter scale. Electromagnetic simulations and experimental measurements demonstrate excellent agreement, confirming the specific near-field behavior and surface-enhanced Raman scattering enhancement factors of the periodic arrays of nanoparticles.

Summary: This paper reports a new reaction-diffusion self-assembly system, in which proteins function as diffusive reactants to assemble stable clay-protein composite hydrogels. Using this method, scalable and highly stable 3D protein patterns can be generated at sub-cellular resolution, and can guide cell behavior to achieve precise bone tissue template formation.

Summary: The creation of complex matter with desired properties through self-assembly is a challenging but promising area of research. The ability to control the interactions between individual components and predict the outcome of self-assembly processes is crucial. This review highlights the role of finely tuned interparticle interactions in achieving preferred self-assembled structures and functional properties. However, there are still challenges ahead in the creation of complex and evolvable matter.

Summary: Controlling the size of COF particles allows for the fabrication of porous photonic crystals (PhCs) with a face-centered cubic arrangement. By adsorbing species within the pores of COF particles, the Bragg reflection can be altered, allowing for the modulation of the structure and properties of the PhCs. Given the abundance of existing COFs and their diverse properties, this discovery is expected to enable the development of colloidal PhCs with unprecedented functionality.

Summary: Interferometry-based, reflectometric, label-free biosensors have made significant progress in the analysis of molecular interactions. Recent studies have focused on ordered porous layer interferometry (OPLI), which uses self-assembled ordered porous colloidal crystal films as interference substrates. These films offer advantages such as low cost, adjustable porosity, and high structural consistency for biosensing applications.

Summary: In this study, the thermophoretic behavior of active colloids was investigated through optothermal interaction, and a re-configurable dynamic assembly was formed using the optical gradient-enabled attraction and short-range repulsion between the colloids. The assembly also exhibited self-evolution as a new colloid joined the structure. Additionally, the structural orientation of the colloids could be modulated by the incident polarization state of the optical field.

Summary: This study presents a novel plasmonic surface-enhanced Raman scattering (SERS) biosensor for quantitative analysis of hematin in erythrocytes without the need for separation from hemoglobin. The biosensor is simple, sensitive, and capable of detecting a wide linear range of hematin concentrations with a low detection limit. These characteristics make it a potential tool for clinical detection of hematin concentrations in human erythrocytes.

Summary: In this study, greatly enhanced light harvesting and one-photon upconversion were demonstrated in plexcitonic hybrids of chlorophyll molecules strongly coupled to silver nanoparticles. The efficient upconversion was predominantly attributable to the one-photon anti-Stokes process, with photon and phonon absorption processes cooperatively enhanced by plexciton resonance. Additionally, coherent plexcitonic Rabi oscillations and plexciton-enhanced triplet-triplet annihilation were also discussed.

Summary: In this study, the inhibitory effects of trifluoroiodomethane (CF3I) and carbon dioxide (CO2) on the explosion pressure and flame propagation characteristics of 9.5% methane were explored using a spherical 20 L experimental explosion device. The results showed that with an increase in the volume fraction of the gas explosion suppressants, the maximum explosion pressure, maximum explosion pressure rise rate, and flame propagation speed of methane gradually decreased, and the time taken to reach these parameters was delayed. The addition of trifluoroiodomethane to carbon dioxide improved the explosion suppression efficiency of carbon dioxide.
