Summary: Hollow mesoporous silica nanospheres were synthesized using pentablock copolymer templates under acidic aqueous conditions, with tetraethyl orthosilicate as the silica precursor. The structure could be tuned by using different length pentablock copolymer templates, resulting in variations in pore structure and morphology. The samples demonstrated hydrothermal stability and the formation of hollow mesopore structures under room temperature conditions.

Summary: Bortezomib-loaded HMSNs (BTZ@HMSNs) system sustains the release of BTZ, inhibits lymphoma cell proliferation and migration, and promotes apoptosis. BTZ@HMSNs downregulate oncogenic genes in lymphoma development, activate p53 signaling, and reduce tumor volume in lymphoma mice model, demonstrating improved tumor-suppressing effect compared to free BTZ. HMSNs show promise as a strategy for delivering therapeutic agents for cancer treatment.

Summary: In this work, Pt-NixOy@HMSNs heteroaggregate nanoparticles were synthesized, featuring Pt-NixOy hybrid nanoparticles inside hollow cavities of mesoporous silica nanospheres. Different Pt/Ni ratios Pt-NixOy@HMSNs were obtained by adjusting the ratios of Pt2+/Ni2+ in micelles. The obtained Pt4-(NixOy)1/x@HMSNs showed enhanced catalytic performance in the hydrolysis of ammonia borane, attributed to the synergistic effect of Pt-NixOy and void confinement.

Summary: Hollow nanostructures with enclosed or semi-enclosed spaces inside are crucial for intrinsic physicochemical properties. A new configuration of hollow nanostructures with more than three layers of shells and integrated mesopores on every shell has been developed, exhibiting periodic interfaces and abundant mesopores. The thermal conductivity is low due to the suppression of gas molecule convection by boundary scattering. This design provides an ideal platform for studying the influence of nanostructure design on intrinsic physicochemical properties and promotes the development of hollow nanostructures.

Summary: Formaldehyde emitted from household products is harmful to human health. This study compares the formaldehyde adsorption characteristics of mesoporous and mesoporous hollow silicas synthesized with or without a calcination process. The mesoporous hollow silica synthesized without a calcination process has the best adsorption performance, followed by the mesoporous hollow silica synthesized with a calcination process and mesoporous silica. This research demonstrates the potential of mesoporous hollow silica as an effective support for harmful gas adsorption.

Summary: Chemo-radiotherapy has significant advantages in treatment and prognosis. This study constructed biodegradable nanoagents that can deliver chemotherapeutics and alleviate hypoxia to enhance chemo-radiotherapy. The nanoagents demonstrated self-activation and on-demand release of the chemotherapeutic drug through stimulation by glutathione (GSH). Moreover, the nanoagents triggered cascade catalytic reactions to alleviate hypoxia and enhanced the chemo-radiotherapy effect. The results suggest that these nanoagents have promising potential for boosting chemo-radiotherapy.

Summary: We report a strategy for the synthesis of chiral mesoporous silica nanospheres with molecular-scale-like chirality. The functionalization of micelles with chiral amide gels leads to the growth of molecularly chiral silica sols, which self-assemble into dendritic large mesoporous silica nanospheres with molecular chirality. The resulting chiral mesoporous silica shows abundant large mesopores, high pore volumes, high surface areas, and exhibits notable optical activity. It also displays good chiral stability and exhibits significant inhibition of β-amyloid protein aggregation formation and cytotoxicity.

Summary: This study fabricated supersmall dendritic mesoporous silica nanospheres (DMSNs) with tunable diameters, serving as nanocarriers for antioxidants and flavoring oils to generate stable emulsions. Gas chromatography-mass spectrometry-olfactometry (GC-MS-O) analysis demonstrated that DMSNs have outstanding protective functionalities for the encapsulated flavoring oil. The research indicates that DMSNs are an ideal platform for stable Pickering emulsions for aromatic compounds, offering a new approach for delivering flavor and sensitive bioactives with excellent stability in various applications such as food, medicine, and cosmetics.
