The sensing platform comprises a direct-type immunoassay involving the selective interaction of PSA with anti-PSA. The surface morphology and analytical performance of the modified SPCE were characterized through relevant instrumentations. The changes in the voltammetric reduction current of AgNPs at 0.11 V in the sensor electrode was correlated to the PSA concentration. Under optimum conditions, the fabricated immunosensor exhibited a sensitive response to PSA with a limit of detection (LOD) of 0.27 ng mL⁻¹ and a dynamic calibration range of 0.75–100.0 ng mL⁻¹. We demonstrated that the participation of AgNPs along with GO modification contribute to the desired signal amplification and sensitive detection of PSA. It is anticipated that the proposed immunosensor can serve as a biomarker and potentially be utilized for the real sample quantification of PSA.]]> Tue 05 Jul 2022 13:29:39 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46133 Thu 30 Mar 2023 17:38:21 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39963 Thu 30 Jun 2022 16:35:31 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41026 Thu 21 Jul 2022 12:22:20 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40482 Thu 14 Jul 2022 08:46:09 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:44455 Thu 13 Oct 2022 15:15:23 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38568 2O4, CoFe₂O₄ and Fe_3,O₄) coated with PEG for MNF formulation and evaluated the loading/release efficacy of doxorubicin (DOX), an anticancer drug. 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://ogma.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://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40144 Thu 02 Nov 2023 13:44:33 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:49704 Mon 29 May 2023 13:00:55 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39296 Mon 29 Jan 2024 18:47:28 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52854 Mon 29 Jan 2024 18:38:31 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40999 Mon 29 Jan 2024 17:56:18 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37934 Mon 05 Jul 2021 13:49:57 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37189 61BM) photoactive system to fabricate highly efficient ternary based bulk heterojunction polymer solar cells (PSCs). The PCBTDPP ternary-based PSC with optimal loading (0.2 wt.%) displayed outstanding performance with a champion power conversion efficiency (PCE) of 5.28% as compared to the PCE (4.67%) for P3HT:PC₆₁BM-based PSC (reference). The improved PCE for PCBTDPP ternary-based PSC can be mainly attributed to the incorporation of PCBTDPP into P3HT:PC61BM that beneficially improved the optical, morphological, electronic, and photovoltaic (PV) performance. This work instills a rational strategy for identifying components (donor/acceptor (D/A) molecules) with complementary beneficial properties toward fabricating efficient ternary PSCs.]]> Fri 28 Aug 2020 15:09:45 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48630 Fri 24 Mar 2023 09:53:50 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50356 Fri 21 Jul 2023 11:13:01 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38284 Fri 20 Aug 2021 16:35:38 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46128 Fri 11 Nov 2022 15:22:03 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55055 Fri 05 Apr 2024 13:53:30 AEDT ]]>
