Cryogenic grinding is a very effective technique for taking hard substances, like plant and animal tissues, and turning them into dust. The tough carbohydrates of plant tissues become very fragile at -196°C and easily shatter. The two concerns with cryogenic grinding is that the sample may warm up, and secondly, throughput is very low.
