Transformation of Smart Sensor Technology in Real World
1-Day Seminar Talk entitled Transformation of Smart Sensor Technology in Real World was held in Bayview Beach Resort, Batu Ferringhi, Pulau Pinang, Malaysia on Tuesday, 23rd of July of 2019. This seminar was launched by Assoc. Prof. Dr. Ruslinda A. Rahim, Director of Institute Nano Electronic Engineering.
More than 46 participants came from Malaysia and Japan was attending this seminar to gain knowledges about new sensor technology. The list of Malaysian Universities participated in this seminar came from Universiti Malaysia Perlis (UniMAP), Universiti Sains Malaysia (USM), University Kebangsaan Malaysia (UKM), Universiti Kuala Lumpur (UniKL), Universiti Pertahanan Nasional Malaysia (UPNM), University Teknologi Malaysia (UTM), Universiti Teknologi PETRONAS (UTP), and Heriot-Watt University.
While the Japan participants came from Osaka University and Tokyo University of Agriculture and Technology. 1-day Seminar Transformation of Smart Sensor Technology in Real World is one of the platforms that can bring in expertise from outside and within Malaysia to see the prospect of sensors and then see the direction of sensor use in today’s world and Malaysia in particular.
Through this workshop, researchers in UniMAP are expected to maintain collaboration between universities within and outside to further enhance extensive sensor-based research. The list of speaker and their talk titles as listed below:

Complementation of ELISA and an Interdigitated Electrode Surface in Gold Nanoparticle Functionalization for Effective Detection of Human Blood Clotting Defects
Abstract – Developing an enhanced diagnosis using biosensors is important for the treatment of patients before disease complications arise. Improving biosensors would enable the detection of various low-abundance disease biomarkers. Efficient immobilization of probes/receptors on the sensing surface is one of the efficient ways to enhance detection. Herein, we introduced the pre-alkaline sensing surface with amine functionalization for capturing gold nanoparticle (GNP) conjugated to human blood clotting factor IX (FIX), and we demonstrated the excellent performance of the strategy. We have chosen the enzyme-linked immunosorbent assay (ELISA) and the interdigitated electrode (IDE), which are widely used, to demonstrate our method. The optimal amount for silanization has been found to be 2.5%, and 15-nm-sized GNPs are ideal and characterized. The limit of FIX detection was attained with ELISA at 100 pM with the premixed GNPs and FIX, which shows 60-fold improvement in sensitivity without biofouling, as compared to the conventional ELISA. Further, FIX was detected with higher specificity in human serum at a 1:1280 dilution, which is equivalent to 120 pM FIX. These results were complemented by the analysis on IDE, where improved detection at 25 pM was achieved, and FIX was detected in human serum at the dilution of 1:640. These optimized surfaces are useful for improving the detection of different diseases on varied sensing surfaces.
