Adsorption of Cytochrome C on New Mesoporous Carbon Molecular Sieves

Abstract: Carbon mesoporous molecular sieves have been prepared from SBA-15 materials synthesized at different temperatures. This allows the synthesis of hexagonally arranged mesoporous carbons with pore diameters between 3.0 nm (CMK-3-100) and 6.5 nm (CMK-3-150). The novel materials have been studied in the adsorption of horse heart cytochrome c from solutions with different pH. A maximal adsorption capacity of 18.5 µmol/g was found for CMK-3-130 (d p ) 4.5 nm) at pH 9.6, which is near the isoelectric point of cytochro… Show more

“…For adsorption isotherm measurements, pH ¼ 9.6 (near the pI of cyt c) and pH ¼ 4.8 (near the pI of BSA) were chosen because the adsorption capacity can be maximized near the pI. [23,54,55,56] The experimental adsorption isotherms of cyt c and BSA on MSNs-C 18 -2 at 30 8C and both pH values as well as their fitting curves by Langmuir equation are shown in Figure 9. All isotherms show a sharp initial rise and then reach maximum adsorption amounts (plateau), suggesting that isotherms are of Langmuir type.…”

“…3A(b)). Recently, Vinu et al reported successful tuning of SBA-15 structure upon control of synthetic temperature [95] and applied the pore-tuned SBA-15 replica to synthesize CMK-3 mesoporous carbon materials with pore diameter ranging from 3 to 6.5 nm [96].…”

“…Adsorption of proteins to mesoporous materials, especially to mesoporous silica, has been rapidly paid attentions [169][170][171][172][173][174][175][176][177][178][179][180][181][182][183][184][185]. As shown below, Vinu et al provide systematic researches on protein adsorption onto mesoporous materials [96,[186][187][188][189][190][191][192][193][194][195][196]. Typical results of adsorption of hen egg white lysozyme and horse heart cytochrome c are shown in Fig.…”

“…Графитовые УНО образуют трехмерную пеноподобную структуру с большой удельной площадью поверхности. Таким обра-зом, УНО наиболее предпочтительны для применения в доставке лекарственных препаратов [6][7][8], разделении газов [9], в топливных элементах [10][11][12] и для очистки воды [13]. Наиболее перспективно применение УНО в качестве материала для изготовления электродов в суперконденсаторах и литий-ионных батареях высокой емкости, которые демонстрируют стабильность характе-ристик при многократной перезарядке [14][15][16][17][18].…”
