Water-dispersible TiO2 nanoparticles via a biphasic solvothermal reaction method
Syntéza ve vodě rozpustných nanočástic z oxidu titaničitého byla dosažena solvotermální dvoufázovou metodou v autoklávu. Byl studován vliv teploty a doby přípravy a dále modifikačních ligandů na stabilitu nanočástic.
Lead Ions Encapsulated in Liposomes and Their Effect on Staphylococcus aureus
The aim of the study was the preparation of a liposome complex with encapsulated lead ions, which were electrochemically detected. In particular, experiments were focused on the potential of using an electrochemical method ...
How Do Grass Species, Season and Ensiling Influence Mycotoxin Content in Forage?
Mycotoxins are secondary metabolites produced by fungal species that have harmful effects on mammals. The aim of this study was to assess the content of mycotoxins in fresh-cut material of selected forage grass species ...
G-Quadruplexes as Sensing Probes
Guanine-rich sequences of DNA are able to create tetrastranded structures known as G-quadruplexes; they are formed by the stacking of planar G-quartets composed of four guanines paired by Hoogsteen hydrogen bonding. ...
Beads-Based Electrochemical Assay for the Detection of Influenza Hemagglutinin Labeled with CdTe Quantum Dots
In this study we describe a beads-based assay for rapid, sensitive and specific isolation and detection of influenza vaccine hemagglutinin (HA). Amplification of the hemagglutinin signal resulted from binding of an ...
An Acetylcholinesterase-Based Chronoamperometric Biosensor for Fast and Reliable Assay of Nerve Agents
The enzyme acetylcholinesterase (AChE) is an important part of cholinergic nervous system, where it stops neurotransmission by hydrolysis of the neurotransmitter acetylcholine. It is sensitive to inhibition by organophosphate ...
The Role of Metallothionein in Oxidative Stress
Volné radikály jsou chemické částice, které obsahují jeden nebo více nepárových elektronů, které mohou být součástí molekuly. Způsobují, že se molekula stává velmi reaktivní. Volné radikály jsou také známo, že hrají dvojí ...
Complexes of silver(I) ions and silver phosphate nanoparticles with hyaluronic acid and/or chitosan as promising antimicrobial agents for vascular grafts
Polymers are currently widely used to replace a variety of natural materials with respect to their favourable physical and chemical properties, and due to their economic advantage. One of the most important branches of ...
Apoferritin modified magnetic particles as doxorubicin carriers for anticancer drug delivery
Magnetic particle mediated transport in combination with nanomaterial based drug carrier has a great potential for targeted cancer therapy. In this study, doxorubicin encapsulation into the apoferritin and its conjugation ...
Behaviour of zinc complexes and zinc sulphide nanoparticles revealed by using screen printed electrodes and spectrometry
(MDPI AQ, 2013-10-25)
In this study, we focused on microfluidic electrochemical analysis of zinc complexes (Zn(phen)(his)Cl-2, Zn(his)Cl-2) and ZnS quantum dots (QDs) using printed electrodes. This method was chosen due to the simple (easy to ...
