New software for scaffolded DNA origami makes it easier to predict what shape will result from a given DNA template.
Protein, RNA, DNA provide very different molecular architectures for nanotechnology to adopt to deliver drugs to cancer cells while sparing healthy cells.
Smaller, faster, cooler: graphene transistors show promise for practical analog signal processors, for magnetic memory devices, and for self-cooling electronic circuits.
‘Good Cholesterol’ nanoparticles are non-toxic and use the need of cancer cells for HDL cholesterol to deliver RNA molecules to silence the expression of cancer-promoting genes.
Phage-assisted continuous evolution of proteins is roughly a hundred times faster than conventional laboratory evolution of proteins, perhaps speeding the development of components for molecular machine systems.
Combined computational and experimental study shows molecules walking, hopping and flying across a surface; may lead to controlling molecular motion.
Porous silica nanoparticles covered with a lipid bilayer deliver large doses of drugs and kill cancer cells a million fold better than do simple liposomes.
The capabilities of scaffolded DNA origami procedures have been expanded to construct arbitrary, two- and three-dimensional shapes.
Real-time monitoring of atomic-force-microscope probes to adjust for wear may speed up and improve the accuracy of measurements and manipulations done with AFMs.
A high-resolution crystal structure of a small square made by self-assembly of RNA molecules reveals each corner of the square to have a unique structure.
