Current Analytical Chemistry - Volume 15, Issue 3, 2019

Background: The article presents the state of research on conductive composite materials constructed on the basis of poly (3,4-ethylenedioxythiophene) (PEDOT), a conductive polymer, as well as selected nanoparticles and nanostructures. Combining two or more materials in a composite which is later used in electrode modification can result in obtaining an electrode with new, more desirable properties. One Read More

Background: Captopril is the synthetic dipeptide used as an angiotensin converting enzyme inhibitor. Captopril is used to treat hypertension as well as for the treatment of moderate heart failure. Analytical instrumentation and methodology plays an important role in pharmaceutical analysis. Methods: This review presents some important applications of electrochemical modes used for the analysis of captopril. So far captopril Read More

Background: Calcium Channel Blockers (CCBs) are widely used in the treatment of cardiovascular and ischemic heart diseases in recent years. They treat arrhythmias by reducing cardiac cycle contraction and also benefit ischemic heart diseases. Electroanalytical methods are very powerful analytical methods used in the pharmaceutical industry because of the determination of therapeutic agents and/or their metabolites in c Read More

Background: The electrochemical sensing of drugs in pharmaceutical formulations and biological matrices using molecular-imprinting polymer (MIP) as a recognition element combined with different electrochemical signal transduction has been widely developed. The MIP electrochemical sensors based on nanomaterials such as graphene, carbon nanotubes, nanoparticles, as well as other electrode modifiers incorporated i Read More

Background: Qualitative and quantitative analysis of atypical antipsychotic drugs used for the treatment of schizophrenia, depression, anxiety, and bipolar disorder obtaining satisfactory results can be ensured by voltammetric techniques. The aim of this review is to present the application of voltammetric techniques developed for the determination of the atypical antipsychotic drugs, which are amisulpride, aripiprazole, cloza Read More

Background: Electroanalytical techniques play a very important role in the areas of medicinal, clinical as well as pharmaceutical research. Amongst these techniques, the voltammetric methods for the determination of drugs using nanomaterials based chemically modified electrodes (CMEs) have received enormous attention in recent years. This is due to the sensitivity and selectivity they provide on qualitative as well as qua Read More

Introduction: Ultra-Performance Liquid Chromatographic (UPLC) method enables analyst to establish an analysis at higher pressure than High Performance Liquid Chromatographic (HPLC) method towards liquid chromatographic methods. UPLC method provides the opportunity to study a higher pressure compared to HPLC, and therefore smaller column in terms of particle size and internal diameter are generally used in d Read More

Background: Diclofenac is a widely used nonsteroidal anti-inflammatory drug. Recent studies have shown that frequent consumption of this drug in high concentrations can cause heart diseases, so strict control of diclofenac’s quantity in commercial drugs is necessary. This paper presents the development of an optimized voltammetric methodology for the quantification of diclofenac, which offers some advantages over other Read More

Background: Nanomaterials have a significant role in improving the performance of electrochemical sensing systems. Unique physical and chemical properties have extended the application of nanomaterials in the fields of engineering, materials and biomedical science. In the last few years, these materials with unique properties have been preferred in the design of experimental approaches for the analysis of metal io Read More

Background: New Chemical Entities (NCEs) could be generally exposed to several stress conditions of hydrolysis, oxidation, photolysis and thermal degradation in order to better characterize the compounds and to know if the degradation processes lead to generate undesired (or toxic) products. Objective: This paper reports the development and validation of an HPLC-PDA method for the qualiquantitative profiles deter Read More
