I have been prepared bovine serum albumin (BSA) capped gold nanoclusters and it has red luminescent in UV light (the procedure was already established). During TEM analysis (200 kv), nanocluster has been charging and  could not identify the particles at higher magnifications. please suggest the ways the sample preparation for TEM measurement or any special conditions need to be for protein analysis in TEM?
