We recently published some work, led by PhD candidate David Macedo, presenting a method to get a more accurate measurement of return peak current in CV experiments. You can read the paper here:
https://pubs.acs.org/doi/10.1021/acs.analchem.3c04181
We've also made a program that automatically performs this analysis, available at https://github.com/davedavedavem/diffusional-fitter
There's some sample data there too if you'd like to try it out.
The current version works for data with a single pair of peaks, but David Macedo is also working on future versions which can handle multi-peak CVs. He's looking at providing more options for capacitive current correction too.
More Accurate Measurement of Return Peak Current in Cyclic Voltammetry Using Diffusional Baseline Fitting
The difficulty associated with accurately measuring the height of the back peak (Ipb) in cyclic voltammetry (CV) has long plagued electrochemists. Most commonly, Ipb is measured by extrapolating a linear fit from a selected region of a voltammogram after the switching potential (Eλ), but without su...

Researchers have shown how thousands of dollars can be shaved off the cost of a portable medical diagnostic instrument by basing it on a small, cheap computer, known as a Raspberry Pi.
Diseases are often diagnosed by quantifying the levels of certain proteins in samples like blood, but this is usually done in a pathology lab using expensive instruments.
The research team, led by Professor Conor Hogan, developed a portable instrument which measures the amount light emitted from samples under electrical stimulation, a process known as electrochemiluminescence.
By significantly reducing the cost of point-of-care medical diagnostic tools, the hope is that disease monitoring could become more accessible in developing countries and remote communities.
