Antibacterial activity of composite of graphene oxide with silver nanoparticles
Bytešníková, Zuzana; Koudelková, Zuzana; Richtera, Lukáš; Kopel, Pavel; Adam, Vojtěch (Mendel University in Brno, 2017-12-31)Looking for strategies against the development of antibiotic resistance is a major global object of interest for the public health. This work deals with synthesis of antimicrobial composites of graphene oxide (GO) with ... -
The Application of Curve Fitting on the Voltammograms of Various Isoforms of Metallothioneins–Metal Complexes
Merlos Rodrigo, Miguel Ángel; Jimenez Jimenez, Ana Maria; Zítka, Ondřej; Richtera, Lukáš; Adam, Vojtěch (MDPI, 2017-03-01)The translation of metallothioneins (MTs) is one of the defense strategies by which organisms protect themselves from metal-induced toxicity. MTs belong to a family of proteins comprising MT-1, MT-2, MT-3, and MT-4 classes, ... -
Composite of graphene oxide with zinc oxide nanoparticles as an antimicrobial agent against pathogenic microorganisms
Bytešníková, Zuzana; Richtera, Lukáš; Kopel, Pavel; Adam, Vojtěch (TANGER, 2017-03-31)The synthesis process of composites based on graphene oxide is described and tested as a carrier of zinc oxide nanoparticles and subsequently tested as an antimicrobial agent for some bacterial strains (Staphylococcus ... -
Influence of liposomal platinum cytostatics on cancer cells by voltammetric methods
Sedláčková, Eliška; Laníková, Petra; Hynek, David; Krejčová, Ludmila; Buchtelová, Hana; Richtera, Lukáš; Adam, Vojtěch (TANGER, 2018-03-31)Aim of this work deals with closing of cisplatin into liposomes, the study of their stability and interaction with cancer cell lines. Commercial cisplatin cytostatic was encapsulated into three types of liposomes (L8, L10 ... -
Interaction of platinum-based cytostatics and platinum nanoparticles with metallothionein - potencial source of the antitumor drug resistence
Zelníčková, Jaroslava; Nejdl, Lukáš; Richtera, Lukáš; Kopel, Pavel; Adam, Vojtěch (TANGER, 2018-03-31)Platinum-based cytostatic represent a unique class of DNA-damaging antitumor agents and they are one the most frequently used drugs in oncology. Problem is that some kind of cancer is resistant against this type of cytostatics. ... -
An Investigation on the Electrochemical Behavior and Antibacterial and Cytotoxic Activity of Nickel Trithiocyanurate Complexes
Amirmansoor, Ashrafi; Kopel, Pavel; Richtera, Lukáš (MDPI, 2020-04-10)The electrochemical redox behavior of three trinuclear Ni(II) complexes [Ni3(abb)3(H2O)3(µ-ttc)](ClO4)3 (1), [Ni3(tebb)3(H2O)3(µ-ttc)](ClO4)3·H2O (2), and [Ni3(pmdien)3(µ-ttc)](ClO4)3 (3), where abb = 1-(1H-benzimidazol- ... -
Preparation and Characterization of Carbon Paste Electrode Bulk-Modified with Multiwalled Carbon Nanotubes and Its Application in a Sensitive Assay of Antihyperlipidemic Simvastatin in Biological Samples
Amirmansoor, Ashrafi; Richtera, Lukáš (MDPI, 2019-06-02)Determination of an antihyperlipidemic drug simvastatin (SIM) was carried out using a carbon paste electrode bulk-modified with multiwalled carbon nanotubes (MWCNT-CPE). Scanning electrochemical microscopy (SECM), scanning ...
