Investigation of the electrical stability of Si-nanowire biologically sensitive field-effect transistors with embedded Ag/AgCl pseudo reference electrode
Bibliographic record
Abstract
We report on the electrical stability of Si-nanowire biologically sensitive field-effect transistors (BioFETs) fabricated using conventional microfabrication technique, with an embedded Ag/AgCl pseudo-reference electrode (pRE) formed by an electrochemical method. The open-circuit potential (OCP) characteristics between the pRE and a commercial reference electrode have been measured in order to evaluate the influence of the pRE potential on the device performance. In a pH sensing mode, the fabricated pRE follows the applied potential accurately with a small offset value of below 6 mV for pH in the range of 4 to 10. The BioFET was also used for the detection of alpha fetoprotein (AFP) with a detection limit of 10 pg mL−1 and the corresponding OCP fluctuation of the pRE was less than 1.5 mV, independent of the AFP concentrations. These results suggest that the Si-NW BioFETs with the embedded Ag/AgCl pRE are very promising for reliable biosensing applications.

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.
