This outcome would suggest that graphene-based nanomaterials may not be suitable for the development of biosensors for the specific biomolecules tested. Further research could focus on understanding the reasons behind the lower performance and exploring whether modifications to the graphene-based nanomaterials or the biosensor design could improve their performance.
Inconsistent results across different biomolecules or graphene-based nanomaterials: If the experiment shows varying results depending on the specific biomolecules or graphene-based nanomaterials used, it would imply that the effectiveness of graphene-based nanomaterials in biosensor development may be dependent on the specific biomolecules or nanomaterials used.
