Triggered Release from Cellulose Microparticles Inspired by Wood Degradation by Fungi
Bibliographic record
Abstract
Triggered compound release has attracted considerable attention in recent years. However, the concepts and carriers reported for triggered release are often complex while nonapproved ingredients are mostly used to make the carriers. In this study, a bioinspired reactive oxygen species (ROS)-mediated delivery system, triggered by light, is introduced. We took inspiration from the well-known ROS mediated degradation of wood (cellulose) by brown-rot fungi and designed microparticles which consist of a core of cellulose nanocrystals, loaded with a drug, surrounded by a light sensitive shell. Incorporating indocyanine green, an FDA-approved photosensitizer, in the shell of the microparticles generates ROS upon NIR laser irradiation, which degrades the cellulose nanocrystals in the microparticles. It was revealed that doxorubicin, encapsulated in the cellulose core and used as a model compound in our study, becomes specifically released upon NIR irradiation of the microparticles. Attractive as well is that the microparticles are prepared by a simple one-step gas-shearing process and fully consist of compounds generally regarded as safe (GRAS).

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.
