Spectroscopic Analysis of Poly (Methacrylic Acid-co-Ethylene Glycol Dimethacrylate) Submicron Particles by Fluorescence Emission and Light Scattering upon Binding with 17β-Estradiol in Water Treatment
Bibliographic record
Abstract
An investigation of light scattering of non-imprinted poly methacrylic acid-co-ethylene glycol dimethacrylate (PMAA-co-EGDMA) submicron particles (3005 nm) in aqueous suspension before and after 17-estradiol (E2) binding was conducted by using a spectrofluorimeter. An optimal excitation wavelength to determine Mie scattering from these submicron particles was 7251 nm for the highest intensity. This light scattering from non-imprinted polymer (NIP) submicron particles in aqueous suspension was increased by spiking E2 at various concentrations (from 0.1 to 1.0 ppm). Thus, a new alternative method was found to determine E2 in a water sample by measurement of light scattering from NIP particles using spectrofluorimetry. Furthermore, the light scattering at 725 nm from E2 solution was increased by spiking NIP particles at various concentrations (from 0.02 to 0.12 ppm) but the fluorescence emission essentially stayed constant. The fluorescence emission from E2, however, increased more significantly in the presence of NIP particles than E2 spiking into water alone.

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.
