NANO-TECHtrahedron: Using nano-structure to check for the probiotic concentration in food sample
In iGEM 2017, our team successfully designed a DNA three dimensional nano-structure to detect the presence and concentration of H3N2 influenza mRNA biomarker. To further prove the ability of the DNA nano-structure, this year we used four DNA strands to form a DNA nano-structure to detect the presence and the concentration of Lactobacillus instead of just a gene fragment of a bacterium. We successfully designed nano- triangular bipyramid applicable to the bacterium using Tiamat. We then successfully detect the presence and concentration of bacteria by measuring its peroxidase activity.
