Researchers seeking to create a biological delivery system that causes minimal cell damage have devised a working nanoinjector that is constructed from carbon nanotubes and guided by a precision microscope. he device can deposit discrete cargos at different sites within a cell — perhaps even within specific organelles — something existing delivery systems cannot do, the researchers said. An added benefit is that the nanoinjector does not require a carrier solvent. The delivery technique offers precision temporal and spatial control, and it caused no discernible cell damage during...Read full article

    microscope
    An instrument consisting essentially of a tube 160 mm long, with an objective lens at the distant end and an eyepiece at the near end. The objective forms a real aerial image of the object in the focal plane of the eyepiece where it is observed by the eye. The overall magnifying power is equal to the linear magnification of the objective multiplied by the magnifying power of the eyepiece. The eyepiece can be replaced by a film to photograph the primary image, or a positive or negative relay...
