Preparation of Well-Dispersed Superparamagnetic Iron Oxide Nanoparticles in Aqueous Solution with Biocompatible<i>N</i>-Succinyl-<i>O</i>-carboxymethylchitosan
Bibliographic record
Abstract
N -succinyl- O -carboxymethylchitosan (NSOCMCS), an amphiphilic polyelectrolyte with the property of biocompatibility and functional carboxyl groups, was used as a stabilizer to prepare a well-dispersed suspension of superparamagnetic Fe 3 O 4 nanoparticles, which were composed of a magnetite Fe 3 O 4 core and a NSOCMCS shell. The carboxyl groups of NSOCMCS can coordinate with Fe 3 O 4, which makes NSOCMCS chemically adsorb onto the surface of Fe 3 O 4 nanoparticles. The stabilizing mechanisms were proven to be both the steric hindrance and electrostatic repulsion arisen from the NSOCMCS. Transmission electron microscopy showed that the resulting Fe 3 O 4 particles were in spherical morphology with the diameter ranging from 12 to 18 nm. Magnetic property measurements indicated that NSOCMCS/Fe 3 O 4 nanoparticles preserved superparamagnetic behavior. In vitro biocompatibility studies showed that the NSOCMCS/Fe 3 O 4 nanoparticles had good cytocompatibility.

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.
