Organic electrolyte gated field effect transistor for detecting alpha synuclein longitudinally in Parkinsonism mouse model
Bibliographic record
Abstract
Parkinson's Disease (PD) is an age-progressive disorder caused by misfolding of alpha-synuclein (α-Syn) that can begin years before clinical symptoms appear, making early diagnosis crucial for timely intervention. In this study, a novel antibody-functionalized Organic Electrolyte-Gated Field-Effect-Transistor (Ab-OEGFET) biosensor was implemented to detect α-Syn levels in blood serum samples from an A53T Transgenic (TG) mouse line. PD-like pathology was examined in blood serum using Ab-OEGFET devices and in brain tissue samples using Western Blot and immunohistochemistry. Different forms (monomeric, phosphorylated, oligomeric) of α-Syn were identified in low volumes of blood serum samples collected from TG and Wild Type (WT) populations of mice at ages 2, 5 and 8 months, and the biosensor response was correlated to Blot and immunohistochemistry results. The Ab-OEGFETs performance in this study is a promising result towards a minimally invasive blood biomarker-based multianalyte testing strategy for early screening of PD and similar neurodegenerative disease pathologies.

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.
