| Summary: | Bionanocomposites are materials composed of particles with at least one dimension in the range of 1-100 nm and a constituent of biological origin or biopolymers. They are the subject of current research interest as they provide exciting platforms and act as an interface between materials science, biology, and nanotechnology and find applications in disciplines such as electrochemistry, biomedicine, biosorption, aerospace, tissue engineering and packaging. They have different properties such as high conductivity, thermal stability, electrocatalytic ability, biocompatibility, adsorption ability and biodegradability, which can be tuned by their preparation methods, functionalities and applications. However, depending on the objective or the goal of a research project, specific preparation and characterization of bionanocomposites can be undertaken to understand the behavior and confirm the applicability of a bionanocomposite in a given field. Like in electroanalysis applications, electrode materials should be porous (meso- and macro-porosities), having large specific area (at least having a Brunauer-Emmett-Teller surface of 200 m

g
−1
), higher stability over time with acceptable power recovery between 95% and 105%, good electrocatalytic ability, and be a good absorbent and a good conductor of electricity (that is to say, it facilitates the transfer of electrons from the solution to the surface of the electrode and
vice versa
). The present review focuses on the most used method of preparation of bionanocomposites with the critical aspect and their physicochemical and electrochemical characterization techniques, and finally, the practical situations of application of bionanocomposite materials as modified electrodes for electroanalysis of several groups of analytes and a comparison with non-bionanocomposite electrodes are discussed. The future scope of bionanocomposites in the field of electroanalysis is also addressed in this review. But before that, a general overview of bionanocomposite materials in relation to other types of materials is presented to avoid any misunderstanding.
Bionanocomposites are materials composed of particles with at least one dimension in the range of 1-100 nm and a constituent of biological origin or biopolymers. |

| Bibliography: | Dr Ranil Temgoua obtained his PhD in Analytical Chemistry in 2020 from the University of Nantes-France and the University of Dschang-Cameroon under the supervision of Dr Mohammed Boujtita and Prof. Ignas Tonlé. He is currently a postdoctoral researcher in the research group of Dr Matthias Koch at BAM-Berlin. Before joining BAM, he was a postdoctoral researcher in the research group of Prof. Antonio Segura Carretero at the University of Granada-Spain and head of the mass spectrometry core facility at YaBiNaPA-Yaounde-Cameroon, under the supervision of Prof. Bruno Lenta. His research is interdisciplinary and focuses on electroanalysis, electrochemistry/mass spectrometry xenobiotics metabolism/degradation-metabolomics. Dr Gullit Deffo is a postdoctoral researcher in the Department of Chemistry, University of Dschang-Cameroon. On 11 April 2023, he publicly defended his PhD degree at the University of Dschang in collaboration with Tezpur University (India), where he was a part-time research scholar under DBT-TWAS postgraduate fellowship. This was done under the supervision of Prof. Evangeline Njanja, Prof. Panchanan Puzari, and Prof. Emmanuel Ngameni. His current research interests are the development of wearable amperometric sensors and biosensors based on several materials science applications for point-of-care devices. Prof. Evangéline T. Njanja is an Associate Professor in the Department of Chemistry at the University of Dschang (Cameroon) where she assists Professor Ignas K. Tonlé to lead a research unit working on the development of electrochemical sensors and biosensors. She also emphasis in the valorization of local materials for the biosorption of pollutants. Under the co-supervision of Professor Maurice L'Her (UMR 6521 laboratory of the University of Bretagne Occidentale, France), and Professor Emmanuel Ngameni (Dean of the Faculty of Science, University of Ngaoundere), she obtained her PhD thesis in 2007 from the University of Yaounde 1 (Cameroon). Prof. Panchanan Puzari is a Full Professor and Head of the Department of Chemical Sciences, Tezpur University, India. He is also the Head of the sensor laboratory in the same Department. He obtained his PhD degree from the Indian Institute of Technology Guwahati in 2008. His current research interests are chemical sensors and biosensors for pesticides, environmental pollutants and human pathological analytes and molecular dynamics of biological processes.
