Summary: Intensive and overuse of antibiotics have led to a rise in antibiotic resistance globally, creating a demand for alternative treatments. Metal ions like copper, silver, and zinc have been used to inhibit microorganism growth for centuries. This study focuses on the synthesis of metal and oxide nanoparticles immobilized on hollow mesoporous silica capsules (HMSCs) for efficient antimicrobial effects against both Gram-positive and Gram-negative bacteria. The results show promising potential for metal-loaded capsules as antibacterial delivery vehicles, providing sustained bacterial inhibition over several hours.

Summary: Functional mesoporous carbonaceous nanomaterials with large pores have wide accessibility and can transport chemicals efficiently in various fields including biomedical applications, gas separation, catalysis, sensing, and energy storage and conversion. The assembly of monomicelles, composed of block copolymers/surfactants and precursor species, has been used to control the nanostructure and mesoporosity of carbonaceous nanomaterials. This method allows for a high degree of control over the final product's structure, making it possible to shape the nanomaterial into unique nanostructures that are otherwise difficult to synthesize using conventional templating methods.

Summary: The study demonstrates that nicotinamide groups grafted on ordered mesoporous silica (OMS) can serve as stabilizers for RhNPs used as catalysts, forming spherical rhodium nanoparticles with a narrow size distribution. On the contrary, amine-functionalized OMS tends to form RhNP aggregates after catalytic reactions, affecting the reaction efficiency. Supported RhNPs also exhibit selective reduction of different groups and show high activity in reductive amination reactions.

Summary: We present the design of novel composite films consisting of cyano-bridged coordination polymers Fe-II[Fe-II(CN)(5)(NO)] or Ag-2(I)[Fe-II(CN)(5)(NO)] grown into a chitosan matrix, which exhibit a slow release of NO radicals under white light irradiation. The characterisation methods confirm that these composites comprise of approximately 50 wt% cyano-bridged coordination polymer microcrystalline particles embedded in chitosan films. Irradiation with white light for 7 days results in a NO radical delivery of 6.5% and 10.6% for {Fe[Fe(CN)(5)(NO)]}(0.55)@C6H11NO4 and {Ag-2[Fe(CN)(5)(NO)]}(0.28)@C6H11NO4, respectively. The rearrangement of cyano-bridged coordination compounds after the departure of NO leads to the formation of Prussian blue or silver Prussian blue analogues, effectively preventing the undesired release of cyanide as a side effect.

Summary: In this study, different strategies are proposed to incorporate methylene blue into porous silica nanoparticles. The design of the synthesis plays a key role in preventing dye leaching and self-aggregation. The negatively charged silica matrix enables the incorporation of the cationic dye without leaching, and the presence of phenyl functions favors the monomeric form of methylene blue. Both dimeric and monomeric forms of methylene blue can generate O-1(2) species when confined inside a silica matrix, exhibiting improved activity compared to the bare dye in solution.

Summary: Luminescent thermometry enables remote temperature detection and has great potential in future technological applications. We demonstrate for the first time that luminescence thermometry can be combined with a complementary temperature readout related to a different property. By taking advantage of the temperature dependence of magnetic and luminescence features in Single-Molecule Magnets (SMM), we develop original dual magneto-optical molecular thermometers that offer a 10-fold improvement in relative thermal sensitivity over the whole temperature range.
