Cryogenic or cold grinding has proved to be the most ideal solution for these types of samples. This involves grinding aids such as dry ice (-78 °C) or liquid nitrogen (-196 °C) that are capable of embrittling the sample by …
In such cases, cryogenic grinding helps to improve the process by embrittling groups of cells and cell walls, making them disrupt more easily and slowing down the subsequent decomposition of the cell fragments. Undesired cell reactions are practically "frozen" by immersing the sample into LN2 so that cell activities can be observed at a ...
