Graphene-based 3D-Printed nanocomposite bioelectronics for monitoring breast cancer cell adhesion

Popis výsledku v původním jazyce

This work examines the suitability of graphene-based 3D-printed nanocomposite bioelectronics as innovative systems to in situ monitor and evaluate both breast cancer cell adhesion and the chemosensitivity of anti-cancer drugs. With this aim, 3D-printed nanocomposite graphene electrodes (3D-nGEs) -made of a commercially available graphene/polylactic acid filament- have been covalently biofunctionalized with an extracellular matrix protein (i.e., fibronectin) by exploiting the carbon reactivity of 3D-nGEs. The specificity and selectivity of the developed electrochemical system to monitor breast cancer cell adhesion has been tested via electrochemical impedance spectroscopy (EIS). Importantly, the resulting 3D-printed bioelectronic system displayed excellent accuracy for the rapid screening of anti-cancer drugs, which exactly corresponded with the results achieved by the standard optical method, while having the advantage of employing a label-free approach. In light of the current state-of-the-art in the field, this proof-of-concept connects electronics to biological systems within 3D printing technology, providing the bases for the sustainable and cost-effective manufacturing of graphene-based 3D-printed nanocomposite bioelectronics to simulate in vivo microenvironments using in situ and real time electronic output signals.
