Disease relevance of tetramethoxysilane

• To study these effects, we have measured the P(+)Q(A)(-) charge recombination kinetics after laser excitation of Q(B)-depleted wild-type photosynthetic reaction centers from Rhodobacter sphaeroides in a tetramethoxysilane (TMOS) sol-gel matrix and, for comparison, also in cryosolvent [1].
• No significant decrease in weight-loss rate was recorded when the CaP fiber tows were pretreated, using conventional application methods, with the tetramethoxysilane sizing for either temperature condition [2].
• Subchronic inhalation toxicity of tetramethoxysilane in rats [3].

High impact information on tetramethoxysilane

• Mesoporous silica, formed by the hydrolysis of tetramethoxysilane (TMOS) in the presence of a triblock copolymer surfactant, was employed for the nucleation and growth of quantum-confined nanowires [4].
• Two different silica monoliths were created from the alkyl silane, tetramethyl orthosilicate (TMOS), by introducing a water-soluble organic polymer, poly(ethylene oxide) (PEO), with varying molecular weights into the prehydrolyzed sol [5].
• Microsomes isolated from rat liver were encapsulated in tetramethoxysilane (TMOS)-based silica matrices within a capillary in a single step under mild conditions [6].
• The hydrophobicity of the xerogels was manipulated by generating xerogels with various molar ratios of propyltrimethoxysilane (PTMS) to tetramethoxysilane (TMOS), from 1:1 to 10:1 [7].
• Treatment of tetramethoxysilane with glycolic acid and morpholine (molar ratio 1:3:2) in methanol, followed by crystallization from methanol/tetrahydrofuran, yielded morpholinium mer-tris[glycolato(2-)-O(1),O(2)]silicate (mer-7) [8].

Anatomical context of tetramethoxysilane

• It was possible to prepare monolithic silica structures in capillaries of up to 200 microm I.D. from a mixture of tetramethoxysilane and methyltrimethoxysilane [9].

Associations of tetramethoxysilane with other chemical compounds

• The gel precursors with tetramethoxysilane (TMOS) and dimethyldimethoxysilane (DiMeDMOS) were deposited on glass supports, and characterized in terms of response to pH, and to dissolved ammonia at constant pH [10].
• Bovine serum albumin (BSA) was encapsulated in tetramethoxysilane-based hydrogel and the enantioselectivity was evaluated [11].
• Under similar conditions, however, the rate of hydrolysis for tetramethoxysilane in deionized water was measured to be considerably slower (k = 0.022 min-1; t 1/2 = 32 min) than that of trimethoxysilane (k greater than 8.1 min-1, t 1/2 less than 0.09 min) [12].
• A method has been developed to cast novel organic/inorganic polymer hybrids from multicomponent solutions containing tetramethyl orthosilicate, calcium nitrate tetrahydrate, polycaprolactone, water, and methylethyketone via sol-gel process [13].
• Hydrolysis rate coefficients of BTMSE, TMOS, MTMS, and BTMSPA are similar in value and are almost one order of magnitude larger than the coefficients of BTMSH and TEOS [14].

Gene context of tetramethoxysilane

• Encapsulation of the homotetrameric pig kidney fructose-1,6-bisphosphatase (FBPase) in tetramethyl orthosilicate sol-gels was used to dramatically reduce the rate of the allosteric transition of the enzyme between the T and R allosteric states [15].

Analytical, diagnostic and therapeutic context of tetramethoxysilane

• Different factors, including drying methods, particle size, surface cations of the phyllosilicate and ratio of phyllosilicate to tetramethyl orthosilicate, were investigated to optimize immobilization conditions [16].
• Scanning electron microscopy of the 1:5 TMOS/n-alkylTMS gels showed a direct correlation between the macropore dimensions and the alkyl chain length of the alkylated precursor and revealed that TMOS/n-octylTMS gels suffered extensive pore collapse during the drying process [17].
