5-fluorouracil adsorption on hydrated silica: density functional theory based-study
(Springer, 2017-04)
Hydrated SiO2(111) has been projected as a competent support of an anticancer drug, 5-fluorouracil (5-FU). Theoretical calculations using the Vienna Ab-initio Simulation Package (VASP) were performed to study the drug-silica ...
Bacterial cellulose-silica organic-inorganic hybrids
(Springer, 2008-06-01)
Bacterial cellulose (BC) hydrated membranes present nanometric reticulated structure that can be used as a template in the preparation of new organic-inorganic hybrids. BC-silica hybrids were prepared from BC membranes and ...
