A nanotech replacement for virus vectors offers a safer way to introduce DNA into cells for gene therapy.
A nanotech formulation may have saved one of the most promising broad-spectrum antiangiogenesis cancer therapies from being side-tracked due to neurotoxic side effects.
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.
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.
The flagellum clutch mechanism may provide ideas useful for nanotech control of molecular motors.
The combination of electrical stimulation and a nanotech surface composed of carbon nanotubes dispersed in polycarbonate urethane was found to attract cartilage-forming cells.
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.
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?
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.
Attaching 12 molecules of an HIV drug to a gold nanoparticle enabled the drug to prevent HIV infection in cultured patient cells.
