The effect of particle interactions on the signal stability magnetic imaging (MPI) and spectroscopy is analyzed. We show that our pre-aggregated flame-made nanoparticles outperform a commercial agglomerating MPI tracer.
The peptide@PEG@MNCs can specifically capture E. coli from a bacterial mixture. antimicrobial susceptibility of the captured be analyzed thereafter by applying sensitive luminescent probe within 30 min.
Sepsis, the systemic response to infection, is a life-threatening situation for patients and leads high mortality, especially when caused by antimicrobial resistant pathogens. Prompt diagnosis identification of pathogenic bacteria, including their antibiotic resistance, are highly desired yield timely decision treatment. Here, we aim develop platform rapid isolation efficient Staphylococcus aureus, most frequently occurring pathogen in sepsis. A peptide (VPHNPGLISLQG, SA5-1), specifically...
Urinary tract infections (UTIs) are among the most predominant microbial diseases, leading to substantial healthcare burdens and threatening human well-being. UTIs can become more critical when caused by Pseudomonas aeruginosa, particularly antimicrobial-resistant types. Thereby a rapid diagnosis identification of P. aeruginosa support guide an efficient medication effective treatment toward UTIs. Herein, we designed platform for prompt purification, combat notorious associated A peptide...
Extracorporeal blood purification has been applied to artificially support kidney or liver function. However, convection and diffusion based systems have limited removal rates for high molecular weight hydrophobic molecules. This limitation is due the finite volume of infusion membrane permeability, respectively. Adsorption provides an attractive alternative higher compounds. The use adsorption resins containing ion exchanging groups capture specific molecules become well-established....
Fluorescent imaging behind turbid layers has recently become available using several different methods based on speckle correlations.The limited range of these correlations embodied in the memory effect, however, leads to a severe limitation field view techniques.Here, we present method iterative scanning and re-focusing wavefront shaping, such that neighbouring regions effect can be imaged.This allows for an extension scattered light fluorescence microscopy far beyond limits given by...
Magnetic nanoparticle-based hyperthermia has emerged as a promising therapeutic modality for treating malignant solid tumors that exhibit resistance to conventional cancer treatments, including chemotherapy and radiation. Despite the clinical approval of superparamagnetic iron oxide nanoparticles (SPIONs) adjunct treatment recurrent glioblastoma, their potential is undercut by chemical synthesis-inherent limitations such low saturation magnetization, characteristics, wide nanoparticle size...
Synthetic antiferromagnet nanoparticles offer unique properties and unify high colloidal stability with strong magnetization. However, their functionality relies on the tight control of directional magnetic anisotropies constituent (antiferromagnetically-coupled) ferromagnetic layers. Here, origin magnitude in-plane Co20Fe60B20 films obliquely sputter-deposited Ta-seed layers are investigated. Uniaxial anisotropy constants in range a few kJ/m3 up to about 25kJ/m3 become accessible. We find...
Abstract Tracer and thus signal stability is crucial for an accurate diagnosis via magnetic particle imaging (MPI). However, MPI-tracer nanoparticles frequently agglomerate during their in vivo applications leading to interactions. Here, we investigate the influence of such coupling phenomena on MPI signal. We prepared characterized Zn 0.4 Fe 2.6 O 4 controlled interparticle distance by variying SiO 2 coating thickness. The silica shell affected properties indicating stronger interactions a...
