Silkweaver says:

These nanostructures could lead to advanced neuro-imaging sensors operating at the cellular scale. Such nanosensors delivered to their targets by chemical tags, or during surgical intervention, could reveal new details about the transmission of neural signals and of their pathological interruption.
