CEMSE Seminar | Integrated and ultrasensitive Biosensors for biomedical, environmental, and food applications

Start Date: February 22, 2017
End Date: February 22, 2017

By Prof. Dr. Mohammed Zourob (Alfaisal University, Riyadh, Saudi-Arabia)
 
 
The challenges for today’s biosensing platforms are numerous: they have to work with real samples, poor detection limit which is far from the infectious dose or the concentrations required by the regulating agencies, suffer from the long analysis time, and use of washing steps and liquids which defeat the purpose of field applications. Another challenge is the stability and availability of highly specific recognition receptors to be integrated with the sensing platform to have a functional device. The presentation will highlights our recent developments to overcome such challenges for various biomedical, environmental, food and security related analytes. We developed various optical, electrochemical, colorimetric sensing platforms and integrate it with various natural and synthetic recognition receptors. We integrated a number of techniques with the various transducers to concentrate and enrich the analyte onto the immobilized recognition receptors on the sensor surface. This technique enhanced and improved the detection limit, shortened the analysis time and reduced the non-specific binding, to reduce the false positive results.
 
Biography: Mohammed Zourob got his Ph.D from the Department of Instrumentation and Analytical Science (DIAS) at the University of Manchester in 2003. He did a postdoctoral scientist at DIAS, working in chemical/biosensors and lab-on-a-chip for biomedical and environmental applications. Then he moved to the Department of Materials Science, University of Manchester, to work on developing high-throughput screening platforms for “Omics” applications. At the end of 2005, he moved to the Institute of Biotechnology, University of Cambridge, where his research focused on optical sensing and biomemetic materials. Dr. Zourob headed the biosensors division at Biophage Inc, a biotech company based in Montreal. In 2009 he joined GDG Environment Ltd as Director of R&D. In 2010 he joint INRS-University of Quebec as associate professor and then he moved to Cranfield University-UK. Now Dr Zourob is holding professor of Biosensors at Alfaisal University-KSA. Prof. Zourob now is leading the Biosensors BioMEMS and Bionanotechnology Lab (BBBL). At anytime the BBBL has minimum 20 researchers working in various projects related to food, biomedical, security and environmental applications. Dr. Zourob has published many scientific papers in peer-reviewed journals, more than thirteen book chapters, and thirteen patents. He edited 6 books in chemical/biosensors, microarray sand lab on a chip. His current theme of research focusing on developing; 1) novel diagnostic tools; 2) highly specific recognition receptors for diagnostic and imaging applications; and 3) lab on a chip systems for sample processing.
