2-Day Course on Nano-Biosensor

October 17, 2014 By Editor

Date: November 24 & 25, 2014
Time: 9.00 a.m. – 5 p.m.
Venue: Institute of Nano Electronic Engineering, UniMAP

Course Background

Biosensor is a short form for “biological sensor”. The device is made up of a transducer and a biological element that may be an enzyme, an antibody or a nucleic acid. The bio-element interacts with the analyte being tested and the biological response is converted into an electrical signal by the transducer. Depending on their particular application, biosensors are also known as immunosensors, optrodes, resonant mirrors, chemical canaries, biochips, glucometers and biocomputers.

The Objectives

Provide an overview on the important aspects and principles of nano biosensor design, fabrication and characterization.
Assist the participants in understanding major fabrication steps and their underlying theories.
Exposure to the sophisticated and state-of-the art nano devices fabrication equipment and tools.

Functionalised zinc oxide nanotube arrays as electrochemical sensors for the selective determination of glucose

September 9, 2014 By Editor

Abstract – In the present study, highly oriented single-crystal zinc oxide nanotube (ZnO-NT) arrays were prepared by a trimming of ZnO nanorods along the c-axis on the gold-coated glass substrate having a diameter of 100–200nm and a length of ~1µm using a low-temperature aqueous chemical growth process. The prepared (ZnO-NT) arrays were further used as electrochemical enzyme-based glucose sensors through immobilisation of glucose oxidase by the physical adsorption method in conjunction with a Nafion coating. The electrochemical response of the sensor was found to be linear over a relatively wide logarithmic concentration range from 0.5×10^-6 to 12×10^-3 M. The proposed sensor showed a high sensitivity of 69.12 mV/decade with R=0.9934 for sensing of glucose. A fast-response time less than 4s with good selectivity, reproducibility and negligible response to common interferents such as ascorbic acid and uric acid prevailed.

Nanogaps Formation Using Scanning Electron Microscope (SEM) Based E-Beam Lithography (EBL) Technique

July 17, 2014 By Editor

Abstract – The semiconductor industry and wafer fabrication developments are driven by customer’s needs. Customers require faster, more reliable and lower cost chips. To achieve this, chip manufacturers and researchers have learned to reduce the size and dimension of component on the chip. The physical dimension of a feature on the chip is referred to as the feature size.[…]

Keywords – semiconductor, fabrication

BioPartnering 2014

Carrying the theme “Generating Biotechnology-based Economy”, BioPartnering 2014 is aimed to serve as a platform to gather all life sciences and biotechnology industry players, entrepreneurs, manufacturers, researchers, academics and head of key R&D&C facilities to explore business potential in the Northern region, as well as to enhance partnership towards accelerating biotechnology product development and commercialization.

The Characterization Study of Functionalized Multi-Wall Carbon Nanotubes Purified by Acid Oxidation

April 15, 2014 By Editor

Abstract – Acid oxidation is one of the purification method which has been used to open up the caps, removing carbonaceous and metal particles impurities, and attaching functional group (carboxylic groups, -COOH) at the opened caps and MWCNT surfaces. Unfortunately, this method can cause the structural damages of MWCNT, cut them into shorter length and reduced their performance. However, it is reported that the structure damage of CNT can be acceptable if it is not exceeding 4% of damages. Several characterization techniques will be used to study the composition of functionalized MWCNT and measuring the percent damages of functionalized MWCNT.

Keywords – mwcnt, cnt, functionalized
