We are interested in a brain mimetic solution or material to record voltammograms using microelectrodes.
Hi Alex
We would routinely use brain tissue homogenate, however, if you don't have access to this then I would recommend looking at individual constituents of brain tissue such as proteins and lipids. These poisons effect electrode characteristics. We use Bovine Serum Albumin (BSA) and Phosphatidylethanolamine (PEA) to mimic the effect of proteins and lipids respectively. TritonX is a surfactant that we would use occasionally too.
However, if you are just wanting to investigate the voltammogram in solution that mimics the ionic composition of the brain then I would suggest artificial cerebrospinal fluid (aCSF). There are a number of recipes for this that you can avail of.
hope this helps.
