The preparation of hollow silica spheres with mesoporous shell via polystyrene emulsion latex template and the investigation of ascorbic acid release behavior

Three-dimensional mesoporous silica networks with improved diffusion and interference-abating properties for electrochemical sensing

“…Mesoporous silica-based architectures are attracting a great deal of interest in numerous fields of materials chemistry [1][2][3][4][5][6]. Templated silicas, either as hollow microparticles [7][8][9] or porous films [10][11][12][13], have recently drawn much attention for sensing and biosensing [14][15][16][17][18][19][20], photocatalytic and optical devices [21][22][23], composites and inorganic-organic hybrids [24][25][26][27], drug-delivery and cancer cell detection [28][29][30], energy conversion and storage systems [31,32], environmental remediation [33][34][35] and even in positronium generation [36]. In this context, the tuneability of the porous network structure and dimension is of primary importance [1].…”

Mesoporous silica reinforced polybutadiene rubber hybrid composite

“…The polymer or reactive groups in the nano-sized pores extending along the channels to the openings will not only enhance the miscibility through the entanglement and inter-diffusion between the matrix and the particulate, but also highly suppress the aggregation of fillers. Though there are a few reports available in the literature regarding incorporation of the mesoporous silica (MPS) in different plastic matrix namely PP, PE, PANI, Epoxy, polycaprolactone, PMMA, PS [8][9][10][11][12][13][14]; the papers which describe the effect of MPSs in elastomers are very scarce [5,15,16]. This paper discusses the effect of variable sized mesoporous silica as reinforcing filler in the polybutadiene rubber matrix.…”

Fabrication of high specificity hollow mesoporous silica nanoparticles assisted by Eudragit for targeted drug delivery

“…Nevertheless, the incomplete removal of polystyrene latex and metal spheres by solvent extraction could cause severe toxic effect for biomedical applications of HMSNs [26,27]. Although polystyrene latex can be completely removed by calcination [28][29][30], the hydroxyl groups are often removed from the surface of the final HMNSs due to the use of high temperature. This will create particles with a surface difficult for further modifications such as conjugating with functional peptides or targeting ligands that are crucial for in vitro and in vivo applications.…”
