Concluding remarks
As a first attempt to study the performance evaluation of this novel CNN on a chip, we can conclude that the growth of cultured neuronal networks was very efficient promoting the formation of neuronal network structures with Small-world properties. One of the most important benefits of the CNN on a chip reported in this article is the simplicity to fabricate custom designs leading the adaptation of the CNNs. We observed that these CNNs on a chip is a reliable and helpful system due to easy handling, renewal of culture medium, avoidance of contamination, control of the culture conditions and whose portability makes straightforward the follow-up of the chip bioreactor chamber where the biological network is formed. Moreover, we found longer survival of the neuronal cultures which opens the possibility to use this CNN on a chip for testing drugs and toxicity in the future, as well as to evaluate different configurations of neuronal circuits on a chip, to extend to biological networks of other type of neurons, or even monitor and test diverse inspired tissues and biopsies on a chip.
