Mesoporous silica nanoparticles (MSN) and periodic mesoporous organosilica nanoparticles containing bridging benzene (PMOBTB) and ethane (PMOBTE) moieties are synthesized, characterized, and evaluated for application in skin protection from UVA/UVB sun irradiation. Furthermore, the influence of surface functionalization with chelating 3-(2-aminoethylamino)propylsilane and Zn ions on the UV-blocking ability of MSN is evaluated, along with the photostability and capability of the synthesized nanomaterials to carry avobenzone, a known UV-absorbing agent. The obtained results reveal promising characteristics of MSN and PMO materials with regard to their potential for sunscreen applications, which could be beneficial in terms of alleviating concerns about health and environmental hazards of sunscreen ingredients.
介孔硅纳米粒子（MSN）和周期性介孔有机硅纳米粒子，其中包含桥联苯（PMOBTB）和乙烷（PMOBTE）部分，被合成、表征，并评估其在皮肤保护方面抵御 UVA/UVB 太阳辐射的应用。此外，还评估了用螯合 3-(2-氨乙基氨基)丙基硅烷和 Zn 离子对 MSN 的紫外线阻挡能力的表面功能化的影响，以及合成纳米材料对阿伏苯宗的光稳定性和承载能力，阿伏苯宗是一种已知的紫外线吸收剂。所得结果表明，MSN 和 PMO 材料具有防晒应用的潜力，这可能有助于缓解人们对防晒成分的健康和环境危害的担忧。
