Malang, Indonesia – 26-27 August 2024 – The 6th International Seminar on Smart Molecule of Natural Resources (ISSMART 2024), hosted by the Asian Federation of Biotechnology (AFOB), successfully featured Assoc. Prof. Ts. ChM. Dr. Nik Ahmad Nizam Nik Malek, Deputy Dean (Research, Development & Innovation) of the Faculty of Science, Universiti Teknologi Malaysia (UTM), as one of the esteemed keynote speakers.
Assoc. Prof. Nik Ahmad Nizam presented his research paper titled “Biological Synthesis of Antibacterial Metal Nanoparticles using Persicaria odorata (Kesum) Leaf Aqueous Extract”, which highlighted his innovative research in sustainable nanomaterial synthesis. His work explored the use of local herbs, specifically Persicaria odorata (commonly known as kesum), to biologically synthesize silver (AgNP) and gold nanoparticles (AuNP).
The study addressed the growing demand for eco-friendly methods in producing metal nanoparticles, known for their excellent antimicrobial properties and biocompatibility. Traditional chemical and physical synthesis methods often involve hazardous chemicals and high energy usage. Assoc. Prof. Nik Ahmad Nizam’s research offered a sustainable alternative by using biological resources, particularly plant leaf extracts, which are both safer and more convenient.
In his research, the aqueous extract of Persicaria odorata—a popular Southeast Asian herb used in culinary dishes such as laksa—proved to be an effective bioreducing and capping agent for synthesizing stable nanoparticles. The kesum leaf extract, rich in bioactive compounds like myricetin-3-glucoside and various flavonoids, demonstrated strong reducing power and antioxidant properties.
During his keynote, Assoc. Prof. Nik Ahmad Nizam also presented findings on the antibacterial and antifungal efficacy of the biosynthesized AgNP, showing their effectiveness against Pseudomonas aeruginosa, Methicillin-resistant Staphylococcus aureus (MRSA), and Candida albicans. Furthermore, the biosynthesized AgNP was evaluated for cytotoxicity and biocompatibility, underscoring its potential for medical applications such as wound healing agents and antimicrobial coatings.
His work represented a major advancement in the fields of nanotechnology and biotechnology, demonstrating how sustainable practices could be harnessed to develop materials with significant applications. Attendees of ISSMART 2024 gained valuable insights into the future of antimicrobial nanomaterials through this informative keynote session.
The seminar, held in Malang, Indonesia from 26-27 August 2024, brought together leading experts in biotechnology, artificial intelligence, and natural resources, focusing on innovative solutions for health and well-being.
Assoc. Prof. Nik Ahmad Nizam’s keynote session was one of the highlights of the event, where he discussed the intersection of natural resources, nanotechnology, and biomedical applications, leaving a lasting impact on the audience.
