Summary

  • The construct folded correctly.
  • The cylinders dimerised correctly. The efficiency depends on the number of connections between the two cylinders
  • The container openes at low pH depending on the salt concentration.
  • The opening also would work in human cells because it works in PBS buffer.

Folding

As a first step, we designed the construct and looked for the best folding conditions. We chose a cylindrical shape with a closed and an open end. [bild, cadnano file]

After some experiments, we decided to use a MgCl2 concentration of 18 mM and an annealing time of 55 h. The pictures of the TEM show that the cylinders have the right shape and size. [tembild]

Dimerisation

We designed four different constructs: with 2,3,4 and 5 pairs of complementary strands. [bild]

More connection strands led to better dimerisation [gel]

Opening

To open the containers we did a buffer exchange.

We exchanged the original buffer with another buffer with low pH. For good results we needed to decrease the salt concentration.[bild]

To show that the opening process would work in the human cell, we used PBS buffer, which is isotonic to the human body.[bild]
