Our results demonstrate the potential for HTP screening methods to be used in the design of polymers that can mimic a whole range of complex therapeutic proteins.]]> Wed 15 May 2024 08:50:44 AEST ]]> Structure-relaxivity mechanism of an ultrasmall ferrite nanoparticle T-1 MR contrast agent: The impact of dopants controlled crystalline core and surface disordered shell https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39803 1 nanoprobe for noninvasive visualization of biological events. However, the structure–relaxivity relationship and regulatory mechanism of UFNPs remain elusive. Herein, we developed chemically engineered 3.8 nm ZnxFe3–xO4@ZnxMnyFe3–x–x–yO4 (denoted as ZnxF@Zn4Mn4F) nanoparticles with precise dopants control in both crystalline core and disordered shell as a model system to assess the impact of dopants on the relaxometric properties of UFNPs. It is determined that the core–shell dopant architecture allows the optimal tuning of r1 relaxivity for Z0.40.4F@Zn0.40.4Mn0.2F up to 20.22 mM–1 s–1, which is 5.2-fold and 6.5-fold larger than that of the original UFNPs and the clinically used Gd-DTPA. Moreover, the high-performing UFNPs nanoprobe, when conjugated with a targeting moiety AMD3100, enables the in vivo MRI detection of small lung metastasis with greatly enhanced sensitivity. Our results pave the way toward the chemical design of ultrasensitive T1 nanoprobe for advanced molecular imaging.]]> Wed 10 Aug 2022 13:11:25 AEST ]]> Gate-Controlled Magnetic Phase Transition in a van der Waals Magnet Fe5GeTe2 https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:49938 Thu 15 Jun 2023 16:14:47 AEST ]]> Direct photocurrent mapping of organic solar cells using a near-field scanning optical microscope https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:1919 Sat 24 Mar 2018 08:33:11 AEDT ]]> Helium detection via field ionization from carbon nanotubes https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:1869 Sat 24 Mar 2018 08:31:18 AEDT ]]> Self-organized monolayer films of stimulus-responsive micelles https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:1413 Sat 24 Mar 2018 08:28:16 AEDT ]]> Near-field scanning photocurrent measurements of polyfluorene blend devices: directly correlating morphology with current generation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:2298 Sat 24 Mar 2018 08:26:57 AEDT ]]> Nearly exclusive growth of small diameter semiconducting single-wall carbon nanotubes from organic chemistry synthetic end-cap molecules https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26980 Sat 24 Mar 2018 07:26:59 AEDT ]]> Spin-Momentum Locking Induced Anisotropic Magnetoresistance in Monolayer WTe<inf>2</inf> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48904 Fri 14 Apr 2023 15:38:15 AEST ]]>
