Abstract
Quantum dots (QDs) containing surface carboxylic groups have been successfully modified using biotinylated glycopolymer and carbohydrate/biotin reagents via EDC coupling. The biotinylated glycopolymer was synthesized in controlled dimension via the reversible addition-fragmentation chain transfer (RAFT) polymerization of the three monomers containing biotin, sugar, and amine groups as pendent groups, respectively. The modified QDs were analyzed by dynamic light scattering and fluorescence spectrophotometry, and the data revealed no change in the physical properties of QDs after surface modification. Furthermore, the surface modified QDs showed excellent water solubility and colloidal stability. Subsequently, the availability of the biotin ligand on the surface of functionalized QDs was quantified using 4-hydroxyazobenzene 2-carboxylic acid (HABA)/avidin binding assay. Cell viability studies revealed that the cytotoxicity of QDs after surface functionalization is improved and that the biotinylated glycopolymer modified QDs showed an enhancement in biocompatibility as compared to that of the original QDs. The biotinylated glyco-functionalized quantum dots may act as new suitable fluorescent probes in biomedical applications.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
