| Summary: | The main objective of this work is to test the sensitivity of a graphene-based
Terahertz sensor, to determine whether it can be used to effectively detect
various substances.
Terahertz technology is a safe technique that does not destroy the analyte, and
has gained increasing popularity in the recent years due to its potential to
analyse biological molecular, cellular, tissue and organs effectively and
safely.
One terahertz technique, known as terahertz spectroscopy has been
introduced and applied in various fields from agriculture to aerospace. In this
project, I work on a terahertz spectroscopy technique known as attenuated
total reflectance (ATR) terahertz spectroscopy. These experiments have been
conducted using different analytes and substrates to test whether there is an
increase in detection sensitivity when a graphene-based sensor is used. As
expected, a graphene-based sensor does improve the sensitivity in detection
of substances. |
