Measurement
All along this year, we have been working in the problematic of how to measure almost any kind of protein with an automated device. We are willing to present our device to this award because we hope that you could see the potentiality of our system in the way in which we see it.
For solving this challenge we have developed two different measuring systems:
The optics approach
For our first approach, we have built, characterized and documented a microfluidic colorimeter, capable of measuring total protein concentration at 280 nm. We have designed all the parts included in the system:
A laser-cut structure.
A microfluidic chip which brings microliters of the sample to the measurement chamber. It handles two experiments at the same time.
An electronic PCBs capable of measure 4 microfluidics chambers at the same time.
A cassette, which carries the microfluidic chip inside it, surrounded by two methacrylate slides with the optic modules housing.
We have also characterized the system with real protein concentrations (BSA), and modeled the system dependence under the change of different variables (time, the temperature of the led…):
