Now days graphene has become very important and its properties are very interesting due to a wide range of possible applications. In this work we studied graphene inks that rise their temperature when an electrical current is applied to them, and we have built a system to study bacteria behavior on temperature gradients generated by graphene inks deposition. Bacteria responds to changing thermal environment by moving towards or away from a particular location, in particular we studied E. Coli response according to temperature gradient generated by graphene inks to observe the effect of temperature over bacteria.InvestigadoresEstudiantes
