LIGHT-INDUCED AGGREGATION OF NANOPARTICLES FUNCTIONALIZED WITH 7-AMINO-4-METHYLCOUMARIN
Bibliographic record
Abstract
Herein, we report on the modification of silica nanoparticles with the molecule 7-amino-4-methylcoumarin (AMC) via a hydrophilic dextran linker using reductive amination chemistry. The AMC-functionalized nanoparticles were shown to aggregate in response to irradiation by 350 nm UV light. The aggregation of the particles was studied using dynamic light scattering, UV-VIS spectroscopy, and transmission electron microscopy. The synthesis method described herein utilizes a classic reductive amination reaction, which can potentially be transferred to a variety of different types of nanoparticles. Particles displaying this behavior have many potential applications in the field of nanomedicine, as they can potentially allow one to modulate the particle size of a nanoparticle formulation after administration to the body. The AMC-functionalized particles studied in this report serve as a convincing proof-of-concept for synthesizing light-responsive nanoparticles.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
