Biosensor Challenge - December 9, 2013

Label-free detection of streptavidin concentration

The challenge: The goal of this challenge was the detection of streptavidin protein binding to biotin and to determine the concentration of streptavidin in molar units. Contestants worked with their own biosensor setup and received biotinylated dextran (as well as thiol-modified biotin) and streptavidin protein. Detection had to be done in aqueous solution using those biological materials.

Contestants had 8 hours to complete the challenge with biological materials handed out at 9am. Results and a short summary of the challenge had to be submitted by 5 pm to the jury. All contestants subseqeuntly gave a short presentation of their approach and results. Based on those presentations the winner was determined.
