Does Favipiravir interact with DNA? Design of electrochemical DNA nanobiosensor to investigate the interaction between DNA and Favipiravir used in the treatment of COVID-19
The SARS-CoV-2 (COVID-19) outbreak has presented a global challenge for both rapid diagnostic tests and therapeutic drugs. In this context, the electrochemical DNA-based biosensor was designed for the investigation of DNA and Favipiravir (FAV) which was one of the drugs used in patients infected SARS-CoV-2 during the pandemic interaction by using bare and multi-walled carbon nanotube (MWCNTs) modified disposable pencil graphite electrode (PGE) for the first time. This drug and its derivatives were used extensively during the pandemic period, and the possible effects of Favipiravir on DNA have not yet been investigated in detail with electrochemical (nano) biosensor technologies. In this study, both the standard form of FAV and the tablet form were used and tested with differential pulse voltammetry (DPV) and cyclic voltammetry (CV) to compare their effects on DNA. Besides, scanning electron microscopy (SEM) was used for the characterization of the developed MWCNTs modified electrochemical DNA biosensor. It was observed that FAV interacts with DNA and causes a significant decrease in the guanine oxidation signal at about +1.00 V. The designed MWCNT-based nanobiosensor was able to detect DNA-Favipiravir drug interaction in FAV concentration as low as 0.66 μg/mL (LOD) with a linear range from 150 to 500 μg/mL. Rapid analysis due to short interaction time (nearly 32 min) was performed.
期刊介绍:
Talanta provides a forum for the publication of original research papers, short communications, and critical reviews in all branches of pure and applied analytical chemistry. Papers are evaluated based on established guidelines, including the fundamental nature of the study, scientific novelty, substantial improvement or advantage over existing technology or methods, and demonstrated analytical applicability. Original research papers on fundamental studies, and on novel sensor and instrumentation developments, are encouraged. Novel or improved applications in areas such as clinical and biological chemistry, environmental analysis, geochemistry, materials science and engineering, and analytical platforms for omics development are welcome.
Analytical performance of methods should be determined, including interference and matrix effects, and methods should be validated by comparison with a standard method, or analysis of a certified reference material. Simple spiking recoveries may not be sufficient. The developed method should especially comprise information on selectivity, sensitivity, detection limits, accuracy, and reliability. However, applying official validation or robustness studies to a routine method or technique does not necessarily constitute novelty. Proper statistical treatment of the data should be provided. Relevant literature should be cited, including related publications by the authors, and authors should discuss how their proposed methodology compares with previously reported methods.
