One of the problems in electrochemical biosensor development and especially when using Electrochemical Impedance Spectroscopy (EIS) is the testing throughput. In a recent effort ZP set up one of new multichannel potentiostats and tested over ninety samples. Though at ZP we still consider ninety a small sample size it is important to be testing as scale so that the decisions or conclusions drawn from the data are based on a large enough body of evidence. The issue both in industry and academia is that conclusions or decisions are based on too small a number of experiments/results.
In our dataset below we were very clearly able to see the trends because the data set was so large.
