Development of microextraction by packed sorbent for toxicological analysis of tricyclic antidepressant drugs in human oral fluid.
The aim of this study was to apply microextraction by packed sorbent (MEPS) to the isolation of six tricyclic antidepressants (TCADs): nordoxepin, doxepin, desipramine, nortriptyline, imipramine, andExpand

Mesoporous carbon-containing voltammetric biosensor for determination of tyramine in food products
AbstractA voltammetric biosensor based on tyrosinase (TYR) was developed for determination of tyramine. Carbon material (multi-walled carbon nanotubes or mesoporous carbon CMK-3-type), polycationicExpand

Tyrosinase-based biosensor for determination of bisphenol A in a flow-batch system.
A tyrosinase-based amperometric biosensor is proposed for determination of bisphenol A (BPA) in a flow-batch monosegmented sequential injection system. The enzyme was entrapped in a sol-gel TiO2Expand

Novel electroanalytical method based on the electrostriction phenomenon and its application to determination of Cr(VI) by the flow injection technique.
The electrostriction phenomenon is observed in membranes of thickness in the nanometer range, e.g. bilayer lipid membranes or self-assembled monolayers. Strong electrical field of 105-106V/cm inExpand

Study on self-assembled monolayer of functionalized thiol on gold electrode forming capacitive sensor for chromium(VI) determination
A capacitive sensor based on S-{12-[1-(pyridin-4-ylmethyl)-1H-1,2,3-triazol-4-yl]dodecyl} ethanethioate (FT), a compound with a functional group exhibiting selective affinity towards Cr(VI) ions, wasExpand

Critical approach to flow injection gradient titration as a calibration method.
An attempt was made to demonstrate that flow injection gradient titration should not be considered as classical titration but rather as the indirect calibration method. This was shown experimentallyExpand
