Lab-on-a-Chip Field Test Findings

Good Morning!

This’ll be quick and easy. We have another update on Lab-on-a-Chip’s field test. If you recall, a few weeks back, one of our Students, Jessica VanderGiessen, who is working alongside Professor Ashley “Unyoung” Kim, recently completed testing the Lab-on-a-Chip arsenic detector in the Bangladesh. 
Jessica presented her findings to Professor Kim and the results were pretty positive, but as with any design project, there is still a long way to go.
The main purpose of this field test was to compare two methods, Cyclic Voltammetry (CV) & Anode Stripping Voltammetry (SV), in a real-world setting with high arsenic concentrations to determine if current testing protocols used in lab settings could still be applied.
Additionally, the Lab-on-a-Chip sensor has a number of design constraints with numerous variable substitutes. This field test would hopefully help to filter through some of the noise and narrow the scope of materials used in future designs and field tests.
The Anode Stripping method proved to be far more successful than the Cyclic Voltammetry method with a success rate of nearly 95% compared to 8%. Additionally the Anode Stripping method was able to confirm the control samples to be arsenic free with 100% accuracy. Pretty great stuff!
Keep it up, Jessica!
Venture Lab -- Design Thinking: Design and Innovate
Since we are on the topic of innovation and design, I thought it would be a great time to plug Stanford’s Venture Lab Courses. Part of the Learning Design and Technology center within the college of education, Venture Labs recently began to offer free, on-line courses in design, technology and innovation. We highly encourage you to check it out.
Till next time,
The Frugal Innovation Lab Team
