Název v původním jazyce

Experimental study of the effect of system composition on artificial chemotaxis of droplets

Popis výsledku v původním jazyce

We tested several dozen systems differing in the type and concentration of surfactant, the length of the hydrocarbon chain of the alcohol forming the droplet and the presence of the dye. Thanks to the obtained information about surface energies and system behavior, we are able to predict the requirements for systems that could be suitable for the study of chemotaxis, namely: 1) surfactant concentration should not exceed CMC to eliminate micelle effects 2) oil droplet should have as much the lowest solubility so that its dissolution does not create the gradient needed for movement 3) the interfacial tension between the droplet and the solution should be very low (around 4 mN/m) 4) the surface tension of the solution must be higher than the surface tension of the droplet. In the following work we will focus on such systems in order to describe in more detail the mechanism of artificial chemotaxis.
