INEE CSR and STEM Programme Series 2

October 10, 2018 By Editor

On the previous 9th October 2018, a Corporate Social Responsibility (CSR) and Science Technology, Engineering and Mathematic (STEM) Programme was successfully organized
by the Institute of Nano Electronic Engineering (INEE), Universiti Malaysia Perlis (UniMAP).

During this time, a total of 10 primary school students from Sekolah Kebangsaan Dato’ Wan Ahmad was given exposure to the knowledge in nanotechnology. They were brought into the INEE laboratory for a tour and were given a new experience and opportunity to operate several equipment.

They were accompanied by two teachers and the most memorable time is when the school’s headmistress was also able to participate in the programme. It is hope that this program and this bond between the school and university will remain in the future.

The ZnO-FET Biosensor for Cardiac Troponin I

July 23, 2018 By Editor

Abstract – This paper investigates the influence of substrate-gate coupling on the ZnO-FET biosensor’s sensitivity for detection of cardiac troponin I (cTnI), a ‘gold standard’ biomarker for acute myocardial infarction (AMI). The FET-based device with introduction of substrate-gate coupling on p-type silicon-on-insulator (SOI) substrate is fabricated using conventional lithography processes. An n-type zinc oxide (ZnO) thin film deposited via electron-beam evaporator is used as transducer for bridging the source and drain regions. Surface modifications via functionalization with 3-aminopropyltriethoxysilane (APTES) and glutaraldehyde (GA) as chemical linkers, followed by immobilization of cTnI monoclonal antibody (MAb-cTnI) as bio-receptor on the ZnO thin film allow different concentration of cTnI detection with high selectivity. The device’s sensitivity increases up to 9 %•(g/ml)-1 with the increase of the substrate-gate voltage (VSG) up to -10 V at very low limit of detection (LOD) down to 1.6 fg/ml.
