Abstract We succeeded in regulating the growth of diatom cells on chemically modified glass surfaces. Glass surfaces were functionalized with -CF3 -CH3 -COOH and -NH2 groups using the technique of self-assembled monolayers SAM and diatom cells were subsequently cultured on these surfaces. When the samples were rinsed after the adhesion of the diatom cells on the modified surfaces the diatoms formed two dimensional arrays this was not possible without the rinsing treatment. Furthermore we examined the number of cells that grew and their motility by time-lapse imaging in order to clarify .
