pH- and redox-triggered synergistic controlled release of a ZnO-gated hollow mesoporous silica drug delivery system
Bibliographic record
Abstract
Hollow mesoporous silica spheres (HMSS) have a hierarchical mesoporous structure composed of a hollow cavity and mesoporous shell available for high capacity drug storage. The covalent attachment of ZnO quantum dots (QDs) to the HMSS outer surface as gatekeepers via disulfide-conjugated two amide linkages encapsulated the anticancer drugs doxorubicin (DOX) within the HMSS cavities and pores, and minimized premature release of the drug. The controlled release of the drug from the ZnO-gated HMSS delivery system was realized by the dissolution of ZnO QDs upon a decrease in pH and cleavage of the disulfide bonds, which indicates that the pH- and redox-responsive controlled release of the drugs could be synergically stimulated by tumor cells with weakly acidic environments and high-expressed glutathione. The constructed ZnO-gated HMSS delivery system has promising applications in site-specific drug release for tumor chemotherapy.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
