Abstract

Superparamagnetic iron oxide nanoparticles (SPION) are material of interest for biomedical research and related applications. Recently, several works have reported facile sonochemical method of functionalizing nanoparticles with organic coupling agents. Herein, we present the influence of ultrasonic irradiation on the rate of functionalization of 3-amino propyl triethoxyl silane (APTES) on SPION. The effect of sonication on the process is investigated by varying the sonication period between 1 and 20min. Grafting of the organo-metallic molecules on SPION is demonstrated through FTIR and XPS. The results show that in one minute, organo-silane compound can be functionalized onto SPION through unique conditions generated from ultrasonic irradiation. The XPS survey spectra of the as-synthesized APTES-SPION at different sonication periods revealed that absorbed energy due to silanization reactions in all the samples appeared at same peaks. The percentage atomic concentrations of all the elements present in the as-synthesized APTES-SPION are determined by the software CASAXPS. The result demonstrated that highest percentage atomic concentration is observed at the one minute sonication period.

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

  • Amorphous SPION obtained from sonochemical synthesis need further heat-treatment after synthesis.

    “Thus, the obtained amorphous SPION need to be further processed by heat-treatment after they have been synthesized [3, 28, 46–48].”
  • Prototypic examples of materials used to coat iron oxide nanoparticles are polymers, fatty acids, amino acids, metals, and oxides.

    “Prototypic examples of materials used to coat iron oxide nanoparticles are polymers [28, 47, 50], fatty acids (like oleic acid, stearic acid, lauric acid and dodecylphosphonic acid) [51–55], amino acids (like phenyl alanine, tyrosine, arginine, lysine and cysteine) [56–58],_metals (like gold, gadolinium and silver) [59–61] and oxides (like silica and TiO2) [62–64].”

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.
