Analysis of the voltage response to identify macromolecule quantities in an electrolyte.

Current techniques of detecting proteins in solution can prove to be time consuming and expensive. Although low cost techniques are available, these are often slow and inaccurate. The authors propose an innovative technique for detecting the presence of proteins and other organic macromolecules in an electrolyte by analyzing the voltage waveform resulting from a biphasic, constant-current, charge-balanced electrical stimulation. Initial experiments have proven the viability of the technique. However due to the limitation of technique accuracy, further refinement of the measurement approach is required.
