We review our ongoing work on deploying optical (atomic) magnetometry for measuring the magnetic response of magnetic nanoparticle (MNP) samples, yielding MNP size distributions, and other sample parameters like Néel relaxation time τ , saturation magnetisation Ms, anisotropy constant K and magnetic susceptibility χ. We address magnetorelaxation (MRX) signals, in which the decaying magnetisatio...

Dual modal nanoprobes are promising tools for accurately detecting target molecules as part of the diagnosis of diseases including cancers. We have explored a new dual modal bioimaging probe that is comprised of a quantum dot (QD)-magnetic nanoparticle (MNP) hybrid. The MNP-QD heterodimers explored are fabricated by using a platinum-guanine coordination bonding guided self-assembly process, emp...

Magnetic nanoparticle-conjugated polymeric micelles (MNP-PMs) consisting of poly(ethylene glycol)-poly(lactide) (PEG-PLA) and iron oxide nanoparticles were prepared and used as nanocarriers for combined hyperthermia and chemotherapy. Doxorubicin (DOX) was encapsulated in MNP-PMs, and an alternating magnetic field (AMF) resulted in an increase to temperature within a suitable range for inducing ...

Introduction: Myocarditis is a major cause of sudden death in young adults, and leads to dilated cardiomyopathy. Despite these significant consequences, the poor sensitivity and specificity of traditional diagnostic modalities have hindered the reaching of a consensus on the clinical practice guidelines for its evaluation and treatment. In this study, we investigated whether MNP (magnetic nanop...

Comparing maps is an important issue in environmental research. Reasons for comparing maps may be: (i) the different socio-economic scenarios on which they are based, (ii) detection of temporal changes, (iii) calibration/validation of land-use models, (iv) hotspot detection, (v) their use in uncertainty analysis, and (vi) their origin in different methodologies/models. This report addresses the...

Ovarian cancer is the fifth-leading cause of cancer-related deaths among women as a result of late diagnosis. For survival rates to improve, more sensitive and specific methods for earlier detection of ovarian cancer are needed. This study presents the development of rapid and specific one-step circulating tumor cell (CTC) detection using flow cytometry in a whole-blood sample with fluorescent ...

Compound 2-chloro-5-nitrophenol (2C5NP) is a typical chlorinated nitroaromatic pollutant. To date, the bacteria with the ability to degrade 2C5NP are rare, and the molecular mechanism of 2C5NP degradation remains unknown. In this study, Cupriavidus sp. strain CNP-8 utilizing 2-chloro-5-nitrophenol (2C5NP) and meta-nitrophenol (MNP) via partial reductive pathways was isolated from pesticide-cont...

Förster resonance energy transfer (FRET) interacted with localized surface plasmon (LSP) gives us the ability to overcome inadequate transfer of energy between donor and acceptor nanocrystals (NCs). In this paper, we show LSP-enhanced FRET in colloidal photosensors of NCs in operation, resulting in substantially enhanced photosensitivity. The proposed photosensitive device is a layered self-ass...

In this paper, we review the investigation for the light-matter interaction between surface plasmon field in metal nanoparticle (MNP) and the excitons in semiconductor quantum dots (SQDs) in hybrid SQD-MNP system under the full quantum description. The exciton-plasmon interaction gives rise to the modified decay rate and the exciton energy shift which are related to the exciton energy by using ...

The impact of finite-sized ions on the diffusiophoresis a charged colloid subjected to concentration gradient electrolyte solution consisting monovalent or multivalent ionic species, is studied. In diffusiophoresis, ion O(1M). this non-dilute solutions, ion–ion steric interaction important. We have adopted Boublik–Mansoori–Carnahan–Starling–Leland (BMCSL) model account for interactions and Batc...
