Abstract:
In this work, we show that sensitive sensing platforms can be derived from the laser irradiation of a non-conducting and flexible material using a laser machine, which can then be used to implement the sensing element of a biosensor to detect and determine the concentration of the target analyte. The aim is to investigate and develop new ways of producing an inexpensive Graphene sensor, implemented as a Radio Frequency (RF) filter for biological application. A Graphene-like material can be produced by the laser irradiation (Laserscribe) of Kapton tape in the form of a filter. The fabrication of this designed filter geometry was achieved by using a laser machine to irradiate the Kapton tape on the chosen substrate (Flame Retardant 4 (FR-4)), by applying the earlier obtained parameters for the fabrication. Several power ratings were used for their fabrication and their conductivity was found to range from 171 x10-6 S/mm to 279 x10-6 S/mm. The ANSYS (Analysis of System) simulation indicates good results, and options to enhance the material property are also being reviewed. Tests are currently on the way to using a Vector Network Analyser (VNA) to verifying their viability of being employed as the sensing element of a biosensor, thereby leading to their potential application in biological sensing.
