Overview

We have accomplished the following:

  • With our original rectangular box design, we have developed a system that can trap, hold, and release nanocargo.
  • We have also opened Han’s sphere in preparation for future nanocargo encapsulation.
  • We are now one step closer to achieving simpler signal amplification, more complex logic gates, and submarine-like drug delivery.

Box Container

Figure 1. Box with Enclosed Gold
  • We have designed and folded two robust origami structures: the lid and the barrel. These two structures are the components of our box.
  • We demonstrate that we can close and open the box with high efficiency.
  • We demonstrate that we can attach AuNP cargo to our lids and/or our barrels and then close the box, placing the AuNP cargo within the box.
  • We demonstrate that we can photocleave the AuNP cargo off of our lids, solubilizing the cargo.

Spherical Container

Figure 2. Open spheres
  • We folded and imaged closed and open sphere structures
  • We began the process of testing lock mechanisms to allow transitions between the closed and open states

Nanoparticles

  • We synthesized 5nm gold particles and conjugated DNA to their surfaces
  • We conjugated DNA to commercially available 5 nm gold nanoparticles
  • We integrated AuNP-DNA conjugates into our rectangular box design

Photo-cleavage

  • We demonstrated photo-cleavage of strands with internal photo-cleavable spacers
  • We outlined a process for the use of photo-cleavable spacers as a means to open our containers and solubilize our cargo
