Abstract In this study, bare gold nanoparticles (GNPs) immobilized in the sol–gel‐pretreated fused‐silica (FS) capillary as a stationary phase for open‐tubular electrochromatography (OT‐CEC) are first time shown to be able separate both hydrophobic polyaromatic hydrocarbons (PAHs) well hydrophilic cationic antimicrobial peptides. Model mixture of four PAHs, naphthalene, fluorene, phenanthrene, and anthracene, was resolved by OT‐CEC GNP‐modified FS capillaries using hydro‐organic background...
To enhance dissolution rate of meloxicam (MX), a poorly soluble model drug, natural polysaccharide excipient chitosan (CH) is employed in this work as carrier to prepare binary interactive mixtures by either mixing or co-milling techniques. The MX-CH three different drug loads were characterized for morphological, granulometric, and thermal properties well crystallinity. relative MX was determined phosphate buffer pH 6.8 using the USP-4 apparatus; significant increase observed both mixed...

Abstract Manganese‐zinc ferrite nanoparticles were synthesized by using a hydrothermal treatment, coated with silica, and then tested as efficient cellular labels for cell tracking, magnetic resonance imaging (MRI) in vivo. A toxicity study was performed on rat mesenchymal stem cells C6 glioblastoma cells. Adverse effects viability proliferation observed at the highest concentration (0.55 mM) only; not compromised lower concentrations. Nanoparticle internalization confirmed transmission...

Magnetic resonance imaging (MRI) reveals anatomical structures with fascinating details, providing efficient diagnostic tool for medicine and powerful non-invasive method biological studies in vivo. Specific contrast labelling agents further enhance MRI applications the most ones might enable even detection of single cells. However, such enormous sensitivity is accomplished only by means magnetic nanoparticles. These so-called susceptibility markedly decrease transverse relaxation time T...
