We first tryed agar. When the agar conzentration is lower than 1.5% the chip is not stable and brakes fast. When the agar conzentration is higher than 1.5% the medium gets solid befor pooring it into chip form. | We first tryed agar.

In the end we choose agarose instead of agar because the agarose is better linked and so the difusion is not so high. | In the end we choose agarose instead of agar because the agarose is better linked and so the difusion is not so high. | ||

+ | First we wanted to produce every chip individually. For a plane surfsace we wanted to use microscope slides. But the agar was to liqued and leaked. After that we made a closed form in which you can give the ager with a pipette. But this chips had big bubbles and were realy difficult to produce. In the end we use a self made open form. Here you produce 9 chips at the same time. You just have to cut them out (anhand) the lasered lines. This is a fast, easy and efficent way to produce chips. And because of the surface tension the chips are plane. | ||
