MEMS Stabilized Lipid Membranes and Their Parylene Encapsulation
Bibliographic record
Abstract
Planar lipid membranes composed of egg phosphatidylcholine and 1, 2-dioleoyl-sn-glycero-3-phosphocholine were suspended over arrays of 100, 75, and 30 μm diameter holes in a 3.7-mm-thick polyimide or 2-μm-thick Parylene film that was supported on a silicon frame. Membranes were allowed to thin in buffer and periodically examined in air with reflected light microscopy. Once the membranes approached the thickness of a bilayer, they were vapor coated with 80 nm of conformal Parylene. The Parylene coating essentially fixed the membranes indefinitely for further study via optical microscopy, scanning electron microscopy, energy dispersive x-ray spectroscopy, atomic force microscopy, white-light interferometry, and confocal microscopy. This paper demonstrated that lipid membranes suspended on microfabricated hole arrays lasted over six days in buffer and that thinning membranes go through a phase where the lipids form lamellar stacks of bilayers within the holes. A technique for encapsulating the suspended membranes in Parylene was demonstrated that enabled detailed measurements of membrane geometry and composition.

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.
