Novel Carboxyl-Amine Bonding Methods for Poly(dimethylsiloxane)-Based Devices
Bibliographic record
Abstract
We present a novel bonding technique for poly(dimethylsiloxane) (PDMS)-based devices employing chemical surface modifications at room temperature. PDMS surfaces were functionalized to present primary amine groups, and glass or gold substrates were functionalized to present carboxylic acid groups. Irreversible bonding was achieved by bringing the two surfaces in contact and reacting at room temperature to form peptide bonds between the substrates. Shear tests reveal the bond strengths achieved to be comparable to values obtained using conventional bonding methods. We also describe the use of carboxyl-terminated silanes on gold surfaces to bond amine-modified PDMS devices. Water contact angle measurements and X-ray photoelectron spectroscopy (XPS) confirmed the conjugation, a novel result that expands the variety of surface chemistries available for such bonding.

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.
