What is the recommended storage conditions for ginger edible nanoparticles? is it -80, -20 or 4C? If -80C, do we need to add any cryoprotectants like glycerol/DMSO? How long the ENPs can be stored at -80C/-20C/4C without loosing the integrity
For short term storage (~3 months) it can be suspended in PBS and stored at -80C. We haven't tested long term storage stability yet. It is recommended to use fresh GDNPs for better results.
