Inhibitory effect of silicon nanowires on the polymerase chain reaction
Bibliographic record
Abstract
The effect of nanomaterials on biological reactions has received much attention. We report herein that silicon nanowires (SiNWs) inhibit the polymerase chain reaction (PCR). The inhibitory effect was found to be concentration-dependent, with a minimum inhibitory concentration of about 0.4 mg ml(-1). DNA polymerase, restriction endonucleases, lysozyme and horseradish peroxidase maintained their bioactivities after exposure to SiNWs. Also the interaction of SiNWs with primers and dNTP did not lead to decreased PCR yield. Compared to primers and dNTP, template DNA showed 4.7-10.5-fold greater adsorption on SiNWs. Template bound to SiNWs was ineffective in the PCR, whereas addition of free template to the PCR system increased the yield. The results of this work suggest that the inhibitory effect of SiNWs on the PCR was due to the selective adsorption of double-stranded DNA on SiNWs, thereby decreasing the availability of template for the reaction.

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.
