Sterilizing the sample for FluidFM experiments


It is important to use sterile sample containers, even for non-biological experiments. Otherwise bacteria can create a biofilm which can clog the FluidFM cantilever and interfere in your experiments. 

Use sterilized consumables (e.g. plates and dishes). In the case of non-sterile consumables, they should be sterilized for example by autoclaving them. As an alternative, you can properly clean them with ethanol. 

A good cleaning protocol for FluidFM experiments is described below (from Guillaume-Gentil et al., 2014):

1. Clean dishes with 2-propanol. 

2. Rinse them with filtered ddH2O. 

3. Dry them with a nitrogen stream. 

4. Plasma-treat them for 2 min. 

5. The dish is now ready for FluidFM experiments.
