Surfaces Modified by Amphiphilic Copolymer: Preparation and Application
Bibliographic record
Abstract
N-isopropylacrylamide (NIPAM)-ethylene oxide (EO) copolymer was grafted on filter paper surface to obtain paper-based adsorptive membrane. Protein adsorption on and release from the membrane was evaluated under various conditions using humanized monoclonal antibody as model protein. The results obtained indicated that amphiphilic copolymer modified filter paper could be used as a novel chromatographic membrane for protein separation/purification. Comb-block copolymers of NIPAM with N-vinylpyrrolidone (VP) were prepared through RAFT polymerization and macromonomer techniques. Surface modification of substrates, such as plastics and glass, was carried out by treatment of the substrates in aqueous solution of the amphiphilic comb-block copolymer (adsorptive coating, pre-adsorption). It was found that the adsorbed copolymer layer was stable in aqueous environment even when shear stress was applied. Protein adhesion on the material surfaces before and after the modification was investigated using lysozyme as model protein. The results obtained showed that the adsorptive coating layer on the material surfaces significantly reduced non-specific protein adhesion.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
