I am conducting research on phytoplasma infection in brinjal (eggplant) little leaf samples and aim to utilize Scanning Electron Microscopy (SEM) for detailed visualization. Could someone kindly provide insights or references regarding the specimen preparation requirements specifically tailored for SEM analysis of phytoplasma-infected brinjal little leaf samples? I am particularly interested in protocols or guidelines for fixation, dehydration, critical point drying, and any other essential steps to preserve sample integrity and facilitate optimal SEM imaging. Any advice or recommended resources would be greatly appreciated.
