Abstract
Abstract Nanocarriers incorporating therapeutic and imaging agents within a single nanostructure are emerging tools for drug development and treatment planning. Additional information can be provided using activatable fluorescence that dynamically reports nanocarrier disruption and drug release. Dual‐wavelength activation encodes a unique fluorescence signal for each nanocarrier state, enabling use of ratiometric imaging to measure the proportion of intact and disrupted nanocarriers within tissues. Here we investigate dual‐wavelength activation using a single dye whose optical properties are intricately linked to the nanocarrier structure. Natural bacteriochlorophyll incorporated within a compact lipoprotein nanocarrier forms ordered dye aggregates with red‐shifted fluorescence emission from 765 nm to 825 nm. We demonstrate that bacteriochlorophyll‐ordered aggregation is a feasible strategy to distinguish intact and disrupted theranostic nanocarriers by ratiometric fluorescence imaging.

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
