CO-Signaling Molecule-Responsive Nanoparticles Formed from Palladium-Containing Block Copolymers
Bibliographic record
Abstract
The overproduction of cell-signaling molecules causes various human diseases. This intrinsic feature offers a biochemical basis to design biosignal-responsive nanocarriers for cell-selective therapy. Here we develop a new palladium-containing block copolymer, which can chemoselectively respond to carbon monoxide (CO)-a crucial gaseous signaling molecule in cells-while inhibiting disturbances from other endogenous analogues. Palladium is introduced into polymer for the first time, and such an organopalladium-connected chain can be cleaved by a CO-induced cascade insertion-elimination reaction, triggering a desirable disassembly of their self-assembling micelles. The micellar dissociation rate depends on the dose of CO stimulus. We envisage that this polymer model would enrich the repertoire of metallopolymers and provide a new platform for designing signaling molecule-responsive macromolecular systems.

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.
