Instruments for Promotion and Assurance of Public Integrity

“The instruments” for supporting the strategies and programmes of public integrity represent a part of a general public integrity framework, comprising also the issue of ethics and public integrity, the legal framework, training and obviously the best practices used successfully by the public organisations. The current paper comprises the instruments concerning the integrity of civil service or institutional organisations, as well as their audit. The paper represents the fourth section of the book: “Public integrity: Theories and Practical Instruments,” published recently by NISPAcee. The first chapter of the paper refers on a large extent to the civil servants’ career, meritocracy, motivation of the civil servants as well as to Whistleblower. The second chapter is dedicated to the instruments concerning the institutional organisations, risk areas for corruption, indicators and transparency, blacklisting. In the third chapter, the audit instruments are aimed at the governmental mechanisms, comprising the method of audit of taxes, public contracts, electronic data etc. The theoretical approaches are accompanied by relevant examples from different state

Inkjet-Printed Carbon Nanotube Electrodes Modified with Dimer-captosuccinic Acid-Capped Fe3O4 Nanoparticles on Reduced Graphene Oxide Nanosheets for Single-Drop Determination of Trifluoperazine

Here, we report the design of a disposable single-drop voltammetric sensor for the quantitative determination of antipsychotic drug trifluoperazine (TFP). The sensor was built using inkjet-printed carbon nanotube (CNT) electrodes, which were modified with dimercaptosuccinic acid (DMSA)-coated magnetite nanoparticles uniformly dispersed over reduced graphene oxide nanosheets (DMSA/Fe3O4/RGO). The used modifying materials were characterized by electron microscopy techniques (transmission electron microscopy (TEM) and field emission-scanning electron microscopy (FE-SEM)), X-ray powder diffraction, \u3b6-potential measurements, dynamic light scattering (DLS), and electrochemical methods (cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS)). The developed sensor, best operated at pH 7 in the Britton\u2013Robinson buffer solution (BRBS), shows linear electrocatalytic activity with TFP in the concentration range of 1\u201350 \u3bcM, a low detection limit of 0.54 \u3bcM, and excellent selectivity, repeatability, and reproducibility with an relative standard deviation (RSD) of 2.4%. A voltammetric approach using square wave voltammetry (SWV) is a sensitive technique under optimized conditions for the analytical determination of submicromolar amounts of TFP. Bare CNT and RGO- and DMSA/Fe3O4-modified CNT electrodes showed lower electrocatalytic activity than the DMSA/Fe3O4/RGO/CNT electrode. The development of this kind of TFP sensor based on nanoparticle-decorated graphene nanosheets can offer a tool for point-of-care applications as sensors in biomedicine
