Cryo-SEM banana skin
The sample of banana skin that was analysed using our cryo-SEM system was taken from directly next to the freeze dried sample on the same banana, making this a directly comparable test. As seen in these images, the hydrated sample is remarkably different. Significantly more detail and fine tissue is preserved, and reveals that the holes in the freeze dried sample developed during the drying process.
Whilst cryo-SEM has many uses, it may not be the best technique for your particular experiment. It can be a lengthy process and only one sample can be analysed at a time, so it is best to discuss the goals of your study with the team at PEMC to ensure the most efficient use of time and instrumentation.
