Abstract

BACKGROUND: Immobilization of lipase on appropriate solid supports is one way to improve their stability and activity, and can be reused for large scale applications. A sample, cost- effective and high loading capacity method is still challenging. RESULTS: A facile method of lipase immobilization was developed in this study, by the use of polydopamine coated magnetic nanoparticles (PD-MNPs). Under optimal conditions, 73.9% of the available lipase was immobilized on PD-MNPs, yielding a lipase loading capacity as high as 429 mg/g. Enzyme assays revealed that lipase immobilized on PD-MNPs displayed enhanced pH and thermal stability compared to free lipase. Furthermore, lipase immobilized on PD-MNPs was easily isolated from the reaction medium by magnetic separation and retained more than 70% of initial activity after 21 repeated cycles of enzyme reaction followed by magnetic separation. CONCLUSIONS: Immobilization of enzyme onto magnetic iron oxide nanoparticles via poly-dopamine film is economical, facile and efficient.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Biomacromolecules such as proteins, peptides, and DNA can anchor on the surface of biosubstitutes via the polydopamine coating layer.

    “In addition, biomacromolecules, such as proteins, peptides, and DNA, can anchor on the surface of biosubstitutes via the PDA coating layer [50, 57–60].”

    From Polydopamine-Assisted Surface Modification for Bone Biosubstitutes (2016) · cites this paper as [60]

    The Background and Results and discussion (‘Lipase immobilization onto PD-MNPs’; page unavailable) say that polydopamine coatings immobilize biomolecules and demonstrate attachment of lipase, a protein, to magnetic iron oxide nanoparticles. Our copy does not specifically establish attachment of peptides or DNA, or address surfaces described as ‘biosubstitutes.’ (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
