Title: Development of Biosensor for Surra (Trypanosoma evansi) based on protein approach using differential pulse voltammetry method
Biography:
April Hari Wardhana currently works at the Department of Parasitology, Indonesian Agency for Agricultural Research and Development. April does research in Biotechnology, Entomology and Parasitology. Their current project is 'Chrysomyia bezziana, Black Soldier Fly, Vectors of Trypanosoma evansi, Trypanosoma evansi, and Protozoan Gastrointestinalis (Giardia, Entamoeba. Eimria and Cryptosporidium)'.
Abstract:
Trypanosoma evansi remains a major cause of Trypanosomiasis in Indonesia, called Surra. However, the lack of accessibility and affordability for diagnostic tests (Card Agglutination Test for Trypanosomiasis/T. evansi – CATT/T. evansi; ELISA and PCR) leads to unsuccessful control of Surra in the field. The study aims to investigate the performance of protein-based biosensor of surra (Trypanosoma evansi) for distinguishing positive and negative sera. Herein, protein was obtained from the T. evansi propagation. This protein was immobilized by carbodiimide reaction on the surface of carbon screen printed electrode as the lowest interaction material with serum/antibody (% I < 90%). The sensor method used in this present study was differential pulse voltammetry (DPV).
Title: Challenge to meet the market need for faster diagnosis in health care: an interdisciplinary approach to biosensors
Biography:
Laure Abensur Vuillaume is emergency physician (M.D) and has completed his PhD in biological science from Lorraine University (France). She works and develops expertise in applied health technologies and medical education
Abstract:
To improve the efficiency of current medical practices, more significant data from technology is needed. One lever to optimize medical decision time is to shorten the delay from biological test to results. In the field of fast biological tests, biosensors have received increasing attention and several technologies have been developed to deliver portable, cheap and sensitive analytical systems(1,2). Nevertheless, two main obstacles prevent the marketing of these biosensors: 1) an accurate analysis of the market in terms of real needs for medical practices and 2) perfect matching with current medical recommendations
Title: Hybrid Two-Dimensional Nanomaterials for Early Cancer Diagnosis Applications
Biography:
Dr. Kumarasamy Jayakumar, Post-doctoral researcher, Bilkent University – National Nanotechnology Research Centre of Turkey, Institute of Materials Science and Nanotechnology in Turkey(2021). Moreover, I had completed my M.Sc. degree at Annamalai University, India in 2007. During, M.Phil., Chemistry from Madurai Kamaraj University, Madurai, Tamil Nadu, India in 2008 and a Ph.D. degree from the Alagappa University, Karaikudi, Tamil Nadu, India in 2015. He received his post-doctoral researcher position at Pusan National University, Busan in South Korea between March 2015 to August 2015 followed by Post-doctoral appointments from Department of Chemistry, Nanjing University, Nanjing, China( 2017 to 2019). He also reviewed high repeated national and international journals and participated in oral presentations for national and international conferences in India, Europe, and China. Currently, He has contributed to published more than eight research articles for high repeated and international journals over the last five years. Although, the electrochemical DNA biosensing articles reached 150 citations and h-index 8 and one book chapter.
Abstract:
The high demand for low cost, the reusable device with short-time the process subsequently able to standard electrochemical biosensing has accelerated the phenomenon. An ambitious development on cancer diagnosis and food science, the consumable gold transducer ensures the fast response, high selective detection, and measurement of various analytes in complicated samples. We exposed that self-assembled monolayer functionalized on hybrids two-dimensional nanomaterials the gold transducer. Due to the advantages of nanostructures, the layer-by-layer assembled with gold nanoparticles (AuNPs) decorating the lower generation (G1-G3) reduced graphene oxide (rGO) core poly(amidoamine) dendrimer (PD) nanohybrids thin film characterized by the spectroscopy techniques. Their morphologies, structures, electrochemical properties, and gene nano biosensing performances characterized and evaluated. AuNPs/GG2PDbased probe displayed the best excellent structural stability, lowest mobility on Au electrode surface with the increasing charge resistance, and the lowest limit of detection (1.87 aM ) in comparison with both AuNPs/GG1PD-based and AuNPs/GG3PD-based probes.
