  • Reconfigurable Transitions between One- and Two

    Coating colloidal particles with DNA provides one of the most versatile and powerful methods for controlling colloidal self-assembly.

  • Programmable patterns in a DNA-based reaction–diffusion

    To trigger programmed pattern formation we loaded initiator strands into cavities in the DNA embedded hydrogel. Depending on the initial (concentrations of initiator strands) and boundary (shape and placement of cavities) conditions gels embedded with identical DNA gates can be programmed to display different spatial dynamics. Step 1 Initiation. Initiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. This signals the DNA to unwind so the enzyme can read the bases in one of the DNA strands. The enzyme is now ready to make a strand of mRNA with a complementary sequence of bases.

Apr 21 2015 · There has been considerable interest in understanding the self-assembly of DNA-grafted nanoparticles into different crystal structures e.g. CsCl AlB 2 and Cr 3 Si. Although there are important exceptions a generally accepted view is that the right stoichiometry of the two building block colloids needs to be mixed to form the desired crystal structure.
