Gaming the Future: The Book!

Category: Nanotech

DNA nanotechnology defeats drug resistance in cancer cells

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.

Nanotechnologies to advance solar energy utilization

Increasing efficiency and utilization and lowering costs for harvesting, converting, transporting, and storing energy produced from sunlight provides a showcase for a variety of nanoscale materials, structures, and processes.

Caltech celebrates ten years of Scaffolded DNA Origami

California Institute of Technology is holding a symposium to honor Paul Rothemund’s seminal contribution to the field of DNA nanotechnology: the research paths opened by the technology, and where they might lead.

Crowd-sourced RNA structure design uncovers new insights

Thousands of amateurs playing the online RNA folding game Eterna, backed up by a real-world automated lab testing their predictions, have provided insights to improve the algorithms computers use to design RNA molecules.

Will medical 3D printing advance nanotechnology?

Do sophisticated medical applications of 3D printing, like printing titanium bones or human tissues, that portend wider use, also perhaps point toward eventual nanoscale applications as the technology improves?

Tightly-fitted DNA parts form dynamic nanomachine

A rotor with DNA origami parts held together by an engineered tight fit instead of by covalent bonds can revolve freely, driven by Brownian motion and dwelling at engineered docking sites.

DNA nanotechnology provides new ways to arrange nanoparticles into crystal lattices

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.

Improving crystallographic resolution through using less perfect crystals

A paradigm shift in analyzing diffraction from smaller, less perfect crystals yields improved resolution and enables directly determining the phase of the diffraction pattern.

DNA nanotechnology cages localize and optimize enzymatic reactions

Encapsulating enzymes in nanocages engineered using structural DNA nanotechnology increases enzymatic digestion and protects enzymes from degradation.

Roles of materials research and polymer chemistry in developing nanotechnology

Polymer chemistry and materials research provide opportunities to explore structures that harmonize phenomena unique to nanoscale technology, the role of mechanical forces generated at interfaces, and the responses of biological systems to mechanical stresses.
