DNA nanotechnology defeats drug resistance in cancer cellsResearchers at The Ohio State University are working to develop DNA nanostructures that deliver medicine to drug-resistant cancer [...]
Triple helices stabilize macroscopic crystals for DNA nanotechnology To self-assemble macroscopic, porous DNA crystals suitable for use as structural scaffolds or molecular sieves, it was first necessary to show [...]
A DNA strand capable of forming a triple helix with a portion of the DNA double helices in a macroscopic DNA crystal enhances the weak interactions holding the crystal together so that the crystal remains stable in the absence of a high ionic strength environment.
Small, stiff, rectangular rods made using scaffolded DNA origami bypass drug resistance mechanisms in the membranes of a cultured leukemia cell line and release enough therapeutic drug to kill the cancer cell.
Two research teams present two different methods for using single strands of DNA to link various nanoparticles into complex 3D arrays: one using DNA hairpins for dynamic reconfiguration and the other using a DNA origami scaffold.
Encapsulating enzymes in nanocages engineered using structural DNA nanotechnology increases enzymatic digestion and protects enzymes from degradation.
DNA building blocks mimic biological ion channels to more precisely control which molecules can cross a biological membrane.
German researchers have used scaffolded DNA origami to adjust the angle of a DNA hinge joint by altering the length of special "adjuster helices", causing molecules attached to the sides of the hinge to be displaced by as little as 0.04 nm.
DNA strands decorating cell membranes like 'Velcro' program the adhesion of cells to other cells or to extracellular matrices to build tiny tissue models.
