Each branch is led by a droplet. However, it is known that bacterial colonies are often more resistant than the individual cells, thereby blurring the borderline between resistance and sensitivity. Moreover, antibiotics affect cells differently, depending on the growth and the physiological state of the cells. The effect of the antibiotic co-trimoxazole on the growth pattern of the vortex branching. Although the available arsenal of Antibiotics contains a variety of functionally and structurally different compounds, resistance mechanisms have been developed for almost all of them.
Resistance can be a cooperative process.
We investigate the response of the colonial growth dynamics to the presence of antibiotics under various stressful conditions in colonies grown on a surface. In particular, we show that bacteria modify their chemotactic signaling in the presence of antibiotics. The idea is to construct nano-particles with a specific and complicated structure that the bacteria have never encounter in nature, have no previously accumulated information of how to their action. Another example has to do with bacterial communication. These are just two simple examples of the endless new possibilities provided by the use of nano-agents.
