Now-a-days, nanotechnology becomes an essential part of modern science especially for its versatile applicability; even in our daily life issues such as disease’s diagnosis, environmental protection, food processing, crystal-clear display, etc. Magnetic resonance imaging (MRI) is a reliable technique to detect various diseases (namely tumor, cancer cell, irregular organs, etc.). Recently, biomedical engineers are paying much interest to improve the imaging performance of MRI machine by utilizing the magnetic nanoparticles as contrast agents. Moreover, the magnetic nanoparticles are studying extensively by the researchers to prevent various environmental pollutions including soil and water.

Bangladesh Nano Society (BNS) arranged a webinar on October 24, 2020 on the topic of “Iron oxide-based nanoparticle for optical, biomedical and environmental applications”. Dr. Md. Mahbubor Rahman (Professor, Department of Chemistry, University of Rajshahi) presented his research findings on the topic. Dr. Md. Mominul Islam (Professor, Department of Chemistry, University of Dhaka) also attended the webinar as a potential discussant and shared his scientific opinion on that topic. The webinar was chaired by Dr. Mohammad Abu Yousuf (Dean, Faculty of Civil Engineering, and Professor, Department of Chemistry, Khulna University of Engineering & Technology, KUET). Dr. Mohammad Mahbub Rabbani (Associate Professor, Department of Chemistry, American International University-Bangladesh, AIUB) conducted the webinar and he has also been working dedicatedly for the improvement of the nano-based scientific research in Bangladesh.

More than two hundred participants including students, researchers, and faculties from home and abroad attended to the webinar. The ‘question answering session’ of that meeting was conducted by Dr. Anwarul Kabir Bhuyan (Professor, Department of Material Science and Engineering, University of Rajshahi). In a relevant discussion, Dr. Al-Nakib Chowdhury (Professor, Department of Chemistry, Bangladesh University of Engineering and Technology, BUET) has emphasized on the necessity of the industry-academy collaboration for the development of nanotechnology-based research in Bangladesh. Finally, the webinar was successfully ended with the concluding remarks by Dr. Md. Jamal Uddin (Professor, Department of Natural Sciences, Coppin State University, USA). It is to be mentioned that BNS arranges such kind of webinars regularly.
