Dr. Naeem Akhtar (Invited Speaker)

IRCBM-COMSATS University Islamabad Lahore Campus

Biography: Dr. Naeem Akhtar received his BS and MS (Physical Chemistry) in 2010 from Department of Chemistry, B. Z. University, Multan Pakistan. He was selected as a senior visiting scholar in 2011 to join National Center for Nanoscience and Technology, Beijing China under the supervision of Prof. He. Tao and was awarded excellent student award. In 2012, he won National institute for material science (NIMS)-Waseda university joint Jr. Research assistantship and became the first Pakistani to Join NIMS as a junior researcher. He started his Ph.D research work in April 2013 under the supervision of renowned Egyptian Scientist, Prof. Sherif El. Safty (Japan has proposed him formally to the Noble prize for chemicals, because of his excellent work in the field of Nanotechnology). During Ph.D research work he won Waseda University, Young Doctoral Scholarship for consecutive three years (1600000 JPY) and also JASSO Honors Scholarship (65000 JPY/month) for a year. He was awarded Ph.D degree with entitle “Doctor of Science” on March 25, 2016 by Waseda University on thesis title “Nanoelectrochemical sensor for selective molecular recognition”.  During PhD he has published 14 articles in International Journals with High Impact. Currently, he is working as an Assistant Professor at Interdisciplinary Research Centre in Biomedical Materials, COMSATS University Islamabad, Lahore Campus and has published more than 30 articles with research areas focusing on, 
fabrication of nano-architectures to design,
(i) Electrochemical and photo-electrochemical sensors for bio-molecular recognition for early stage diagnostic applications, and

(ii) Energy storage devices.

Title of Speech: Carbon encapsulated Cu nanohybrid: Sensor to monitor phenolic pollutants and catecholamines

Abstract: Despite the magnificent advancement in sensing techniques, precise monitoring of phenolic pollutants and catecholamines with high sensitivity and selectivity from real life environmental or biological samples is highly demanded not only to cure but also to diagnose several diseases. Additionally, control monitoring and quantification of these phenolic pollutants and catecholamines from real samples such as commercially available pesticides and urine respectively, is quite challenging because of their low concentration along with excess of co-existing interfering species. To overcome these challenges, herein, for the simultaneous electrochemical monitoring of these phenolic pollutants and catecholamines we fabricated C encapsulated three-dimensional Cu nano-particles through a simple, scalable freeze-drying and carbonization process. The resulting nano-hybrid contains 3D arrangement of controlled Cu nano-particles with atomic arrangement along all four lateral faces with sharp apex which result in exposition of greater fraction of Cu {111} catalytic active sites, large number of sp2 carbon atoms, and maximum surface defects along with dipolar/quadrupolar radiative plasmons, thus offering highly sensitive and selective behavior towards simultaneous monitoring of phenolic pollutants and catecholamines even from commercially available insecticide and urine of neuroblastoma patient, respectively. The results demonstrated the potential of the designed electrode not only to use in preventing serious health issue associated with phenolic pollutants but also in diagnosis of suspected catecholamine secreting tumors.
