Resistance impact by long connections on electrical behavior of integrated Memristive Biosensors

Abstract

Abstract-Integration of nanowire structures in more complex platforms combining microfluidics and multiplexing aspects may complex the electrical readout process. In the present work, fabrication of Aluminium (Al) lines for electrical connections is attempted followed by their integration to nanofabricated Memristive Biosensors that target at the labelfree detection of cancer biomarkers. In addition a computational study is carried out investigating the impact of the resistance introduced by the additional Al connections to the electrical response of the Memristive Biosensors. Overall, the present study explores the restrictions and the possibilities of the Memristive Biosensors' integration with additional elements that would allow effective readout in more complex configurations.

Multi-Panel, On-Single-Chip Memristive Biosensing

“…The metal lines are designed taking into consideration the fact that the hysteretic properties of the memristive biosensors are sensitive to additional resistive elements introduced in series to the nanofabricated devices, eliminating or even completing masking the memristive properties of the nanodevices. For this reason, the extension lines design follows the outcomes of a relevant computational study and calculations [9], [13] for respecting the resistance tolerance of the system. A common source and separated drains are considered for individual measurement of twelve integrated sensors (as seen in Fig.…”
