Binding of Streptavidin with Biotinylated Thermosensitive Nanospheres Based on Poly(<i>N,N</i>-diethylacrylamide-<i>co</i>-2-hydroxyethyl methacrylate)
Bibliographic record
Abstract
Thermosensitive polymer nanospheres based on N,N-diethylacrylamide and 2-hydroxyethyl methacrylate (HEMA) have been prepared, characterized, and conjugated with biotin. The thermosensitivity of poly(N,N-diethylacrylamide) was enhanced by the incorporation of HEMA up to about 40 mol %. Atomic force microscopic images show that these particles can be closely packed even without the surface charges as in the latex particles. Biotinylation reduces the thermosensitivity of the copolymer nanospheres. The biotinylated hydrogel nanospheres showed a reduction in size upon binding with streptavidin, indicating the formation of a less hydrophilic conjugate. No aggregation of the biotinylated particles due to the cross-linking effect of streptavidin was observed. This size change could be reversed by the addition of free biotin to the system. The interaction is specific, and no such changes were observed when streptavidin was replaced by bovine serum albumin.

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.
