A visit to INEE was conducted by Associate Professor Dr. Rafeezul Mohamed from the Department of Biomedical Science (IPPT), USM Bertam, on November 14, 2024. Among the discussions held were research collaboration activities between INEE and IPPT in the fields of nanomaterials and biomedicine. Thank you once again.
Abstract – The field of generating surface thin films in sensing applications is emerging, and the incorporation of thin film technology into sensor development for enhanced sensing is becoming increasingly significant in various industries such as healthcare, environmental monitoring, and food safety. However, in order to achieve higher specificity in biosensing, advances in nanomaterial biofunctionalization are crucial. This research focuses on the fabrication and characterization of nanobiosensors with surface modification using two different sensing materials: zinc oxide and gold nanorod nanocomposites. The aim of this study was to enhance the sensing capabilities of nanobiosensors by incorporating surface modification with different sensing materials. The fabrication of nanobiosensors involved using silicon as the base material and conventional photolithography to fabricate aluminium interdigitated electrodes with three different structures and gap sizes. AutoCAD software was utilized to create three different photo masks with varying gap sizes. Physical characterization of the fabricated ALIDEs was conducted using atomic force microscope, high power microscope, scanning electron microscope, and 3D-profilormeter. The electrical characterization of the ALIDEs was performed using a Keithley 6487 picoammeter. I-V measurements were conducted on bare ALIDEs as well as surface modified ALIDEs with zinc oxide and gold nanorod. I-V measurements were also performed for pH scouting. The I-V measurements on bare ALIDEs revealed that ALIDEs modified with gold nanorod conducted the least current compared to ALIDEs modified with zinc oxide. Furthermore, the ALIDEs modified with gold nanorod were found to be stable under various electrolytes environments after undergoing pH scouting.

An engagement session aimed at improving the management of research instruments in Malaysian public and private universities was held on October 15, 2024, at the Royal Chulan Georgetown Hotel, Penang.
The session, hosted and organized by Universiti Teknologi MARA (UiTM), was attended by Assoc. Prof. Dr. Foo Kai Loong and Dr. Mohamad Faris Mohamad Fathil. Among the topics discussed were significant challenges or obstacles in maximizing the research potential at Malaysian public universities, such as inefficiencies in resource allocation, lack of maintenance funding, and the absence of a comprehensive monitoring system.
Addressing these challenges through systemic reforms and strategic investment is crucial to advancing the research and innovation agenda. This session was part of a Short-Term Study funded by the Ministry of Economy, led by UiTM.
Congratulations to Prof. Dr. Subash Gopinath on his appointment as a Visiting Professor at the Center for Global Health Research, Saveetha Medical College & Hospital, Saveetha Institute of Medical and Technical Sciences (SIMATS), Thandalam, Chennai, Tamil Nadu, India. May this appointment continue INEE’s excellence and bring great benefits to both parties.
A collaborative research discussion between INEE, UniMAP, and the Malaysian Nuclear Agency (ANM) took place on August 16, 2024, at the Office of the Deputy Vice-Chancellor (Research & Innovation) of UniMAP. ANM was represented by Ts. Dr. Ishak bin Mansor, Deputy Director General (Technical Services Program).
This visit coincided with the Basic Biosensor Fabrication Workshop at INEE, attended by 8 staff members from ANM. The workshop took place from August 12 to 16, 2024. It is hoped that the planned research activities will bear fruit and benefit both parties.
