Summary: We synthesized a co-condensed hollow ethane-bipyridine periodic mesoporous organosilica (HEt-bpy-PMO) as a host material to anchor lanthanides for developing a multifunctional chemical sensor. The luminescence properties of the developed hybrid materials were studied in detail in the solid-state and after dispersing in water. The Eu3+ or Tb3+ incorporated materials showed ions selectivity towards Cu2+, Co2+, and Fe3+ as ion sensors, and exhibited excellent acetone sensing selectivity.

Summary: Biomimetic core-shell nanoparticles - silica nanocapsules were recently developed using a designer dual-functional peptide SurSi under environmentally friendly conditions, allowing precise control of peptide-induced biosilicification for the formation of oil-core silica-shell nanocapsules with uniform size and monodispersity. The fundamental mechanism of silica formation through peptide catalyzed biosilicification was systematically investigated to optimize the formation of biomimetic silica nanocapsules, providing valuable insights for making core-shell nanoparticles via controlling nucleation and reaction at interfaces.

Summary: Hollow nanoparticles have advantages in high loading capacity and stability, but their application in the food field is limited due to complex preparation process and harmful raw materials. In this study, hollow gliadin nanoparticles (HGNPs) were developed using a Na2CO3 sacrificial template method. HGNPs were found to be an effective delivery system for resveratrol (Res), showing smaller size, better stability, higher encapsulation efficiency, stronger UV resistance, and sustained release in the gastrointestinal tract compared to solid gliadin nanoparticles (SGNPs). This work is of practical significance for developing and utilizing protein-based nanoparticles with hollow structures as delivery systems for sensitive bioactives.

Summary: A method was developed to synthesize hollow mesoporous nanoparticles with controllable size and shell thickness for drug-delivery applications. Monodispersed hollow mesoporous organosilica (HMOS) and hollow mesoporous silica (HMS) nanoparticles were successfully prepared using soft and hard templating methods. The hollow size of HMOS can be tuned by changing the size of the hard templates, and the shell thicknesses of HMOS and HMS can be adjusted by changing the amount of precursor used.

Summary: The study developed a one-step strategy to fabricate raspberry-like hollow periodic mesoporous organosilica (RHPMO) with tunable surface structures and high specific surface area. This preparation method unexpectedly shares a similar protocol as the classical one for making spherical PMO. The dynamic formation process of RHPMO was detected by TEM, showing that controlling condensation and adsorption of precursor/surfactant assemblies is crucial for forming the final nanoparticles.
