Graphene for Electrochemical Sensors

Dr. Marlinda bt Ab Rahman is a leading scientist from the University of Malaya with expertise in Graphene for Electrochemical Sensors.

Currently, she works on the synthesis and fabrication of graphene/natural rubber latex and rubber band composite for sensor applications.

As a result of the advancements in nanotechnology, numerous techniques for sensing have been developed, and each method has its own advantages and disadvantages. To date, various analytical techniques for the detection of nitrates and nitrites such as atomic absorption spectrometry, injection inductively coupled plasma mass spectrometry, capillary electrophoresis, micro X-ray fluorescence (μ-XRF), Ion chromatography, HPLC-UV/VIS spectrometry (UV-VIS) and chemiluminescence are available. However, these spectrometric methods require expensive instrumentations and are not suitable for in situ analysis due to their ponderous nature and the need for professional operators to handle complicated tools. Thus, a simple and inexpensive method that not only detects but also quantifies analytes is desirable for the real-time monitoring of environmental, biological, and industrial samples. On the contrary, the electrochemical methods are considered as an alternative to these expensive spectroscopic techniques, which are well proved as an efficient method to detect analytes. The advantages of electrochemical analysis include high sensitivity, high accuracy, wide measuring range, simplified device architecture which are economical, user-friendly, reliable, and suitable for in-field applications.

She is going to deliver a lecture on “Graphene for Electrochemical Sensors” in UIT webinar series on 20th March 2022 organized by Universal Intellectuals Trust (UIT).
