Mesostructured Silica for Optical Functionality, Nanomachines, and Drug Delivery
Open accessAbstract
Silica thin films and nanoparticles prepared using sol–gel chemistry are derivatized with active molecules to generate new functional materials. The mild conditions associated with sol–gel processing allow for the incorporation of a range of dopants including organic or inorganic dyes, biomolecules, surfactants, and molecular machines. Silica nanoparticles embedded with inorganic nanocrystals, and films containing living cells have also been synthesized. Silica templated with surfactants to create mesostructure contains physically and chemically different regions that can be selectively derivatized using defined techniques to create dynamic materials. Using two different techniques, donor–acceptor pairs can be doped into separated regions simultaneously and photo‐induced electron transfer between the molecules can be measured. Mesoporous silica materials are also useful supports for molecular machines. Machines including snap‐tops and nanoimpellers that are designed to control the release of guest molecules trapped within the pores are described. Mesoporous silica nanoparticles are promising materials for drug delivery and other biomedical applications because they are nontoxic and can be taken up by living cells. Through appropriate design and synthesis, multifunctional mesoporous silica nanoparticles for sophisticated bio‐applications are created.

Azobenzenes attached to the interiors of inorganic subtract pores templated by surfactant can act as both impellers and gatekeepers.
“The azobenzenes attached to the interiors of the inorganic subtract pores templated by surfactant [507,508] can act as both impellers and gatekeepers [509,510].”
From A review of stimuli-responsive shape memory polymer composites (2013) · cites this paper as [509]
Section III(2) says azobenzenes attached to the interiors of surfactant-templated pores can function as nanoimpellers. It also describes pore-blocking molecular machines and lists azobenzene-based controlled-release systems, but does not specifically say those pore-attached azobenzenes act as gatekeepers.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
