The Faculty of Engineering (FE) at AIUB organized a webinar titled "Terahertz Technology applied in Microfluidics with life saving analysis in health industry" on Thursday, October 07, 2021 in Dhaka from 7:30 PM to 9:00 PM. The webinar was held on Zoom online platform and was joined by about 100 participants. Mr. Shahebul Hasan (Lecturer, EEE, AIUB) served as the moderator of the event. The webinar was inaugurated by Dr. ABM Siddique Hossain (Professor and Dean, Faculty of Engineering, AIUB). In his welcome speech, Prof. Hossain spoke about Japanese researchers' progress in studying human tissues on cell/molecular levels using Terahertz technology and the potential of such research for medical purposes.
The distinguished guest speaker of this webinar was prominent researcher Dr. Feroz Ahmed (Scientific Researcher, Okayama University, Okayama, Japan). At the start of his talk, Dr. Ahmed introduced the Advanced Electro-Measurement (AEM) Laboratory, which he is a part of and shared the contributions of AEM lab in developing biomedical engineering applications. Then, he offered a brief overview of Terahertz (THz) technology properties that make it suitable for spectroscopy and imaging and allow the detection of small water content fluctuations in chemical and biological substances like pH buffer solutions tissues and blood. Next, he discussed the practical necessity of visualization of flow of fluids through microflow channels and compared Terahertz Chemical Microscope (TCM) against conventional PSI and CCD camera methods. Dr. Ahmed also explained the comprising elements of TCM and its working principle, following up with a schematic demonstrating an experimental arrangement with TCM. In the latter half of the talk, the speaker provided the definition of Microfluidics and talked about their applications in experimental science and engineering where their micron level scale can be useful to capture cells, germs and nanoparticles. After sharing the 2D simulation result, Dr. Ahmed finally introduced the step-by-step fabrication process of Microfluidic chip on a sensing plate, going through Solidworks Isometric design, 3D printed structure, and the final chip made of PDMS (polydimethylsiloxane), and reported a good match between simulated and experimental results. He concluded the presentation with a summary of their current research work and future planned tasks.
After the end of the speech, there was a question-answer session where Dr. Ahmed responded to the questions raised by the audience. Dr. Toshihiko Kiwa (Professor, Faculty of Engineering, Okayama University, Okayama, Japan) from AEM lab also spoke a few words thanking the organizers and expressing interest in future collaborations. The closing remarks were provided by Dr. Mohammad Nasir Uddin (Senior Associate Professor, Head of the Graduate Program, Dept. of EEE). He expressed gratitude to Dr. Ahmed for his informative presentation and extended an invitation to him for future events organized by AIUB. The event was concluded by offering the speaker a digital Certificate of Appreciation as a token of gratitude for sharing his valuable time and insight. Dr. Md. Abdur Rahman (Professor and Associate Dean, Faculty of Engineering, AIUB), Md. Abdul Mannan (Professor and Director, Faculty of Engineering, AIUB), Mr. Nafiz Ahmed Chisty (Associate Professor and Head In-Charge, Dept. of EEE, AIUB), and Mr. Md. Saniat Rahman Zishan (Associate Professor and Head, Dept. of CoE, AIUB) co-hosted the event.
