https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48034 Thu 16 Feb 2023 10:43:07 AEDT ]]> Fluoride-assisted detection of glutathione by surface Ce³⁺/Ce⁴⁺ engineered nanoceria https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52445 4+/Ce³⁺ compositions. Using DFT calculations combined with Bader charge analysis, it is demonstrated that stoichiometric ceria registers a higher oxidase mimetic activity than oxygen-deficient ceria with a low Ce⁴⁺/Ce³⁺ ratio due to a higher charge transfer from a substrate, 3,3',5,5' tetramethylbenzidine (TMB), to the ceria surface. We also show that the fluoride ions can significantly increase the charge transfer from the TMB surface to ceria irrespective of the surface Ce⁴⁺/Ce³⁺ ratio. Using this knowledge, we first compare the fluoride sensing properties of nanoceria with high Ce⁴⁺ and mixed Ce⁴⁺/Ce³⁺ oxidation states and further demonstrate that the linear detection range of fluoride ions can be extended to 1-10 ppm for nanoceria with mixed oxidation states. Then, we also demonstrate an assay for fluoride assisted detection of glutathione, an antioxidant with elevated levels during cancer, using nanoceria with a high surface Ce⁴⁺/Ce³⁺ ratio. The addition of fluoride ions in this assay allows the detection of glutathione in the linear range of 2.5-50 ppm with a limit of detection (LOD) of 3.8 ppm. These studies not only underpin the role of the surface Ce⁴⁺/Ce³⁺ ratio in tuning the fluoride assisted boost in the oxidase mimetic activity of nanoceria but also its strategic application in designing better colourimetric assays.]]> Thu 12 Oct 2023 15:28:04 AEDT ]]> Position and force sensing using strain gauges integrated into piezoelectric bender electrodes https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38561 Thu 04 Nov 2021 11:38:10 AEDT ]]> Feasibility of gold nanocones for collocated tip-enhanced Raman spectroscopy and atomic force microscope imaging https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:55044 Thu 04 Apr 2024 13:51:54 AEDT ]]> Direct tip-sample force estimation for high-speed dynamic mode atomic force microscopy https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:19800 Sat 24 Mar 2018 07:57:11 AEDT ]]> A review of demodulation techniques for multifrequency atomic force microscopy https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38352 Mon 30 Aug 2021 15:59:32 AEST ]]> Design and analysis of low-distortion demodulators for modulated sensors https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:35718 Mon 20 Nov 2023 15:36:20 AEDT ]]> Integrated force and displacement sensing in active microcantilevers for off-resonance tapping mode atomic force microscopy https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:40682 Mon 18 Jul 2022 09:35:13 AEST ]]> Adaptive scan for atomic force microscopy based on online optimization: theory and experiment https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:44539 Mon 17 Oct 2022 09:24:30 AEDT ]]> Dynamics and control of active microcantilevers https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48261 Mon 13 Mar 2023 14:53:44 AEDT ]]> AFM cantilever design for multimode Q control: arbitrary placement of higher order modes https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38576 Mon 08 Nov 2021 15:23:08 AEDT ]]> Active atomic force microscope cantilevers with integrated device layer piezoresistive sensors https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:40181 Mon 08 Aug 2022 13:26:19 AEST ]]> Model-based Q factor control for photothermally excited microcantilevers https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45890 Mon 07 Nov 2022 16:30:12 AEDT ]]> Modeling and noise analysis of a microcantilever-based mass sensor https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45887 Mon 07 Nov 2022 16:30:04 AEDT ]]> The Generalized Lyapunov Demodulator: High-Bandwidth, Low-Noise Amplitude and Phase Estimation https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50810 Mon 07 Aug 2023 11:19:33 AEST ]]> Lyapunov estimator for high-speed demodulation in dynamic mode atomic force microscopy https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36067 Mon 03 Feb 2020 14:54:11 AEDT ]]> Multimodal atomic force microscopy with optimized higher eigenmode sensitivity using on-chip piezoelectric actuation and sensing https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:34500 Fri 31 Jan 2020 15:05:08 AEDT ]]> A review of demodulation techniques for amplitude-modulation atomic force microscopy https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30249 Fri 24 Aug 2018 09:02:14 AEST ]]> Higher-harmonic AFM imaging with a high-bandwidth multifrequency Lyapunov filter https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33848 Fri 18 Jan 2019 14:48:48 AEDT ]]> Experimental analysis of tip vibrations at higher eigenmodes of QPlus sensors for atomic force microscopy https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47336 Fri 13 Jan 2023 12:02:31 AEDT ]]> Chemical bond imaging using torsional and flexural higher eigenmodes of qPlus sensors https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51546 Fri 08 Sep 2023 14:58:30 AEST ]]>
