Huda Abdullah is a professor in department of Electrical, Electronic and Systems Engineering, Faculty of Engineering and Built Environment, Universiti Kebangsaan Malaysia, Malaysia. My academic strength lies in the field of Nano Functional Material with a specialization in material for energy and sensor application.

In 2007, I awarded For Women In Science (FWIS 2007) by L`oreal Malaysia. In June 2011, I obtained an international grant, COMSTECH-TWAS Research Grants for dye-sensitized solar cell application. In 2012, I was successfully obtained 1 Internal grant (UKM), and two national grants (ERGS and e-ScienceFund), beside I was awarded as a young scientist by The Malaysian Solid State, Science and Technology Society (MASS).

In July 2013, I obtained an international grant, Islamic Educational, Scientific and Cultural Organization (ISESCO) Research Grant for microbial detection sensor. Up to now, I obtained 18 research grants as a project leader. I have published more than 150 research papers in journals and conferences (ISI/SCOPUS).

In December 2013, I was selected as a member of Young Scientist Network-Academy of Sciences Malaysia (YSN-ASM) for 3-years-term until December 2016. On 6th May 2014, I was selected to join the ‘Talent Prospect under Talent Management: Media Event Showcasing Research Universities’ Success Stories Exhibition, Category: Young Researcher, held at Universiti Putra Malaysia (UPM).

In October 2014, I was awarded “Anugerah Inovasi UKM” (Individual Researcher category), by Universiti Kebangsaan Malaysia. In February 2015, I was selected to be a member of the Young Global Academy (GYA) for a 5-year term, from February 2015 until January 2020. In December 2019, I was awarded Top Researcher Scientist Malaysia (TRSM) by Academy Science of Malaysia (ASM).

Herein, we report the fabrication of polyaniline with Ag-Pt alloy nanocomposite thin films based amperometric E. coli sensor. The effects of annealing at 300oC during the synthesis of PANI-Ag-Pt nanocomposite thin films are studied. XRD, AFM, FESEM and FTIR spectroscopy analysis are conducted to characterize the films. Sensor performance is investigated by I-V characteristic of PANI-Ag-Pt films with and without the presence of E. coli. From XRD analysis, annealed films have larger crystallite size than non-annealed films. AFM results indicate annealed films have lower surface roughness but larger grain size than non-annealed films. FESEM images show Ag-Pt nanorods with size of 200-300 nm for non-annealed films and Ag-Pt nanocubes with size around 100-550 nm for annealed films. The composition of PANI-Ag0.2-Pt0.8 nanocomposite thin film has the higher conductivity and performed the maximum sensitivity upon E. coli presence. The sensitivity of annealed PANI-Ag-Pt films is higher than non-annealed PANI-Ag-Pt films.
