DNA architecture log
The tRiton Nano Architect spent a large effort in brainstorming project ideas from April 2012 to July 2012. Our effort help us learn the process of DNA nanotechnology as well as the current research stage of DNA nanotechnology. We analyzed various scientific papers cited from the resource section of past BIOMOD 2011 teams. With this knowledge, the project scope and project budget was taken into consideration when selecting our actual project/abstract.

Project Ideas
Idea | Concept | Uses | Reason Rejected | Sources |
---|---|---|---|---|
DNA sensing circuit with DNAzymes |
This idea utilizes DNAs conductivity. Many structural versions of this design were contemplated but the most popular structure was interlocking rings of DNA in a Y shape, which would be connected to two electrodes at one end and one at the other. On one of the Ys would contain aDNAzyme, so cleavage of that strand of DNA would occur when a trigger of a specific DNA sequence was added. | The idea was that this could be used in sensing. Once the target sequence of DNA (ie, a specific virus) was present, the DNAzyme would break, and the current across the chain would change. | While it was feasible, our mentor said this would be too hard to optimize in the given time due to the complexity of the interlocking rings and measuring the charges. | DNA attachment chemistry: http://journals.ohiolink.edu/ejc/article.cgi?issn=07437463&issue=v15i0019&article=6541_eirodfgu

DNA Robotic Arm with Light-activated Joints and Tweezers as Hands |
This idea was inspired by DNA walkers. We wanted to see if we can create the arms of a molecular robot, knowing that others have already designed the legs. Our robotic idea utilized DNA tweezers as hands and photoreceptive molecules that would change chemical conformation in order to bend the "shoulders", "elbows", and "wrists" of the DNA arms. We planned to test our project by attaching it to a platform and controlling it with light to pick up nanoparticles placed on certain locations. | Based on our current skills, the idea was unfeasible. | text for row 1, column 3 | |
