We have presented in detail the drug loading capacity and the time-dependent cumulative drug release of DOX from PEG-coated MNPs based MNFs. Specifically, we have selected three different MNPs (NiFe₂O₄, CoFe₂O₄ and Fe₃O₄) coated with PEG for the MNFs and compared their variance in the loading/release efficacy of DOX, through experimental results fitting into mathematical models. DOX loading takes the order in the MNFs as CoFe₂O₄ > NiFe₂O₄ > Fe₃O₄. Various drug release models were suggested and evaluated for the individual MNP based NFs. While the non-Fickian diffusion (anomalous) model fits for DOX release from PEG coated CoFe₂O₄, PEG coated NiFe₂O₄ NF follows zero-order kinetics with a slow drug release rate of 1.33% of DOX per minute. On the other hand, PEG coated NiFe₂O₄ follows zero-order DOX release. Besides, several thermophysical properties and magnetic susceptibility of the MNFs of different concentrations have been studied by dispersing the MNPs (NiFe₂O₄, CoFe₂O₄ and Fe₃O₄) in the base fluid at 300 K under ultrasonication. This report on the DOX loading/release capability of MNF will set a new paradigm in view that MNF can resolve problems related to the self-heating of drug carriers during mild laser treatment with its thermal conducting properties.]]> Thu 04 Nov 2021 13:58:14 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38378 2O₂) production has attracted considerable attention as a renewable and environment-friendly method to replace other traditional production techniques. The performance of H₂O₂ production remains limited by the inertness of graphitic carbon nitride (CN) towards the adsorption and activation of O₂. In this work, a photocatalyst comprising of β-cyclodextrin (ß-CD)-modified CN with supporting Au co-catalyst (Au/β-CD-CN) has been utilized for effective H₂O₂ production under visible light irradiation. The static contact angle measurement suggested that β-CD modification increased the hydrophobicity of the CN photocatalyst as well as its affinity to oxygen gas, leading to an increase in H₂O₂ production. The rate of H₂O₂ production reached more than 0.1 mM/h under visible-light irradiation. The electron spin resonance spectra indicated that H₂O₂ was directly formed via a 2-electron oxygen reduction reaction (ORR) over the Au/β-CD-CN photocatalyst.]]> Thu 02 Sep 2021 12:42:32 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:40144 Thu 02 Nov 2023 13:44:33 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48630 Fri 24 Mar 2023 09:53:50 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38284 Fri 20 Aug 2021 16:35:38 AEST ]]>
