Catalytic nanomaterials, widely used as substitutes of peroxidase, exhibit unique properties, which are unattainable for native enzymes. However, their activity is usually examined by means substrates developed and methods standardized horseradish peroxidase (HRP). The aim the presented work was to determine scope usefulness chromogenic gold nanoparticle (AuNP) studies under conditions significantly extend beyond range a HRP. applicability chromogens such 3,3'5,5'-tetramethylbenzidine (TMB),...
A schematic representation of the aptamer–antibody sandwich assay.
Abstract Most point-of-care tests (POCT) use swabs for sampling and/or applying a sample on the test. A variety of differing in tip materials is commercially available. Different have different chemical and physical characteristics which might influence specimen collection release. We investigated properties various types used clinical diagnostics with focusing two kinds analytes, DNA proteins, are most often targets POCT. As model samples we diphtheria toxoid NIBSC 69/017 investigating...
Hepatocellular carcinoma (HCC) was the third leading cause of cancer-related death globally in 2020. The treatment disease is complex, with a high possibility recurrence. low survival rate HCC patients due to their late-stage diagnosis. Hence, best prognosis diagnose at an early stage. diagnosis made through imaging methods and, selected cases, by biopsy. These diagnostic tools fail for detection HCC. are time-consuming and expensive, especially resource-limited healthcare settings....
Nucleic acid extraction and purification are crucial steps in sample preparation for multiple diagnostic procedures. Routine methodologies of DNA isolation require benchtop equipment (e.g., centrifuges) labor-intensive steps. Magnetic nanoparticles (MNPs) as solid-phase sorbents could simplify this procedure. A wide range surface coatings employs various molecular interactions between dsDNA magnetic nano-sorbents. However, a reliable, comparative evaluation their performance is complex. In...
Rapid and accurate detection identification of pathogens in clinical samples is essential for all infection diseases. However, the case epidemics, it plays a key role not only implementation effective therapy but also limiting spread epidemic. In this study, we present application two nucleic acid isothermal amplification methods-reverse transcription helicase dependent (RT-HDA) reverse loop-mediated (RT-LAMP)-combined with lateral flow assay as tools rapid SARS-CoV-2, etiological agent...
A group of amides and oxamides has been used as potential ionophores for lead ions in solvent polymeric membrane electrodes. The most favourable analytical results (slope, log kPb,M lifetime) were obtained with membranes incorporating ionophore ETH 295 potassium tetrakis(p-chlorophenyl)borate. With the use these membranes: (i) a linear response slope 35.3 mV per pPb unit PbII an activity range 10–5.2–10–1.0M obtained; (ii) selectivity factors (log kPb,M) lower than –1.5 respect to studied...
Electrochemical assay for the universal biomarker of several cancers, urokinase plasminogen activator, uPA, based on uPA-specific fluorinated RNA aptamer and methylene blue redox indicator, allows 1 pM uPA analysis in serum, making it practically useful clinical applications.
The aim of this work was to carry out comparative studies on the peroxidase-like activity gold nanoparticles (AuNPs) stabilized with low molecular weight hyperbranched polyglycidol (HBPG-OH) and its derivative modified maleic acid residues (HBPG-COOH). influence stabilizer precursor ratio size morphology obtained checked, prepared were characterized by means transmission electron microscopy UV-Vis spectroscopy. results indicated divergent effect increasing concentration stabilizers (HBPG-OH...
