A new type of filler was added to epoxy resin to prepare a composite coating with excellent corrosion and weathering resistance. The simple synthesis process and nonpolluting raw materials of this filler contribute to the development of green chemistry. Specifically, lignin was encapsulated in mesoporous silica, the synergistic effect between the two resulted in the formation of lignin/mesoporous silica composite particles (MSN-L) with excellent ultraviolet (UV) resistance.

In most studies, the penetration of nanoparticles into tumors was mainly dependent on the enhanced permeability and retention (ERP) effect. However, the penetration of nanoparticles would be limited by tumor-dense structure, immune system, and other factors. To solve these problems, macrophages with active tropism to tumor tissues, loaded nanoparticles with photothermal therapy, and chemotherapy were designed.

Mesoporous silica particles are of great interest in the field of dental composites as functional inorganic fillers due to their unique interconnected pores which can form micromechanical interlocking at the filler-resin interfaces. However, the degradation of mesoporous silica is fast in wet environments, leading to the poor mechanical stability of dental composites. Here, we synthesized Zr-doped mesoporous silica spheres (Zr-MSS) to increase the chemical stability of the particles.

The sensitive detection of inflammatory biomarkers in gingival crevicular fluid (GCF) is highly desirable for the evaluation of periodontal disease. Luminol-based electrochemiluminescence (ECL) immunosensors offer a promising approach for the fast and convenient detection of biomarkers. However, luminol's low ECL efficiency under neutral conditions remains a challenge.

Mesoporous materials have garnered significant interest because of their porous structure, large surface area and ease of surface functionalization to incorporate the functional groups of choice. Herein, chiral mesoporous silica nanoparticles (CMSNPs) were prepared using quaternary amino silane as the template, tetramethyl orthosilicate as the silica source and proline and cellulose as chiral selector. The developed CMSNPs were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), elemental analysis, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction analysis, BET surface area analysis and BJH pore size/volume analysis.
