Gaming the Future: The Book!

'Cooking' cancer cells with nanotechnology

Antibody-coated carbon nanotubes only bind to cancer cells targeted by the antibody, and irradiation with near-infrared light causes the bound carbon nanotubes to heat up and kill the cancer cells.

Nanotechnology approach to drug delivery uses multifunctional nanoparticles to silence gene

A major nanotech advance in engineering multifunctional nanoparticles for imaging and therapeutic applications combines a short RNA (siRNA) to “silence” a specific gene with quantum dots and a “proton sponge” polymer coating to get the siRNA into the cell and released into the right compartment of the cell.

Molecular clutch for bacterial flagellum may offer control mechanism for nanotechnology

The flagellum clutch mechanism may provide ideas useful for nanotech control of molecular motors.

Using nanotechnology to attract cells to regenerate cartilage

The combination of electrical stimulation and a nanotech surface composed of carbon nanotubes dispersed in polycarbonate urethane was found to attract cartilage-forming cells.

Nanotechnology engineers single molecules as nanorobots

Chemists have designed molecules that act like nanotech sensing robots by signaling information about their chemical environment.

Stripes improve drug delivery using nanotechnology

MIT scientists are discovering what controls the proper movement of nanoparticles into cells—the right kinds of molecules must be arranged in the right patterns.

Which way(s) to advanced nanotechnology?

Will nanotechnology culminate with diamondoid nanorobots produced in nanofactories by atomically precise mechanosynthesis, or with “soft” machines that mimic the way biological molecular machines work?

Artificial organelles: nanotechnology beyond simple drug delivery

The same nanotech approaches being explored to deliver drugs exactly to the cells where they are needed also provide a technology base that might lead to permanent enhancements of human metabolism.

Nanotechnology combines multiple molecules of drug to prevent HIV infection

Attaching 12 molecules of an HIV drug to a gold nanoparticle enabled the drug to prevent HIV infection in cultured patient cells.

Nanotechnology builds artificial virus for possible therapeutic use

Filament-shaped artificial viruses show promise in delivering genetic materials and other molecules into cultured human cells.
