“…HR-TEM micrographs revealed the size, shape, and dispersity of TB MSN. Earlier studies clearly point out to the fact that the size, shape, porosity, and dispersive nature of MSN have major roles in enhancing their loading capacity (Mehmood et al 2017).…”

In the present study, the antimicrobial and antibiofilm efficacy of toluidine blue (TB) encapsulated in mesoporous silica nanoparticles (MSN) was investigated against Pseudomonas aeruginosa and Staphylococcus aureus treated with antimicrobial photodynamic therapy (aPDT) using a red diode laser 670 nm wavelength, 97.65 J cm À2 radiant exposure, 5 min). Physico-chemical techniques (UV-visible (UV-vis) absorption, photoluminescence emission, excitation, and FTIR) and high-resolution transmission electron microscopy (HR-TEM) were employed to characterize the conjugate of TB encapsulated in MSN (TB MSN). TB MSN showed maximum antimicrobial activities corresponding to 5.03 and 5.56 log CFU ml À1 reductions against P. aeruginosa and S. aureus, respectively, whereas samples treated with TB alone showed 2.36 and 2.66 log CFU ml À1 reductions. Anti-biofilm studies confirmed that TB MSN effectively inhibits biofilm formation and production of extracellular polymeric substances by P. aeruginosa and S. aureus. ARTICLE HISTORY

“…4 A network of mesopores would greatly increase the binding surface and therefore render many more binding points accessible to sorbates. Commonly, mesoporous templating in sol-gel processes employs surfactant micelles as template [13][14][15][16][17] ; however, this approach was ineffective due to interference of the biopolymers with the formation of surfactant micelles. It has recently been demonstrated that mesoporous sol-gel structures may be obtained by deep-eutectic solvent (DES) templating.…”

A study on the Pb(II) imprinting performed within mesoporous sulphated biopolymer/siloxane composites, prepared in media containing deep eutectic solvent (DES), is described. In general, the process of imprinting resulted in greatly increased surface areas relatively to the corresponding nonimprinted composites [up to fivefold (from 76 m2 g−1 to 360 m2 g−1) for fucoidan (Fuc) and up to twofold (from 208 m2 g−1 to 351 m2 g−1) for chondroitin sulfate (CS) composites], the diminishing of mean pore size (from 3.3–4.6 nm to 2.9–3.4), and higher biopolymer contents (from mass fractions of 0.42–0.52 to 0.46–0.68). The sorption features depended a great deal on the biopolymer/DES combination. The best CS composite, allowed for 12% capacity and 20% binding strength, as well as Pb(II)/Cd(II) selectivity enhancements. The largest of the capacities was obtained with the imprinted Fuc/DES‐E composite, 86 mg g−1, a 10% increase. Concerning the selectivity [Pb(II) versus Cd(II)], there was a significant increase for the CS composites (from 1.0–1.1 (αqmax)/1.1–1.2 (αK) to 1.3–1.4 (αqmax)/1.3–1.6 (αK)]. In particular, the DES‐E CIC presented high selectivity factors (αqmax 3.0/αK 3.2) in line with those of the microporous version (αqmax 2.0/αK 3.3) but showing a significant increase in terms of the αqmax selectivity. © 2019 Wiley Periodicals, Inc.

“…The general synthesis strategy of micelle templated silica (MTS) involves the condensation of an appropriate monomer in the presence of a templating agent (Figure 2). The templating agent is later removed from the composite material by soxhlet extraction, hot filtration or calcinations revealing a network of pores [3][4][5]. Surfactants are the commonly used template sources in the synthesis of micelle templated silica materials.…”

Mesoporous Materials - Properties and Applications

Preparation of useful materials using renewable resources, which are not in competition with food production is of particular importance in the current efforts to replace non-renewable resources. One example of a potential renewable resource, which is attracting the attention of researchers in the preparation of useful materials is cashew nut shell liquid (CNSL). CNSL which is a by-product of cashew processing factories, is a mixture of four potential compounds, namely anacardic acid, cardanol, cardol and 2-methyl cardol. Among other potential applications, cashew nut shell liquid is a good template source for preparation of mesoporous materials. Heterogeneous catalysts prepared using CNSL templates are more efficient than those prepared using the commercially available templates. The pore sizes of mesoporous materials prepared using CNSL templates are large (up to 25 nm) enough to immobilize enzymes. Another renewable resource; castor oil, has also been reported to be a good template source for preparation of mesoporous materials. This chapter therefore is aimed at describing in detail the preparation, characterization and applications of mesoporous materials templated by cashew nut shell liquid and castor oil.
