Gevorg Grigoryan, an assistant professor of computer science at Dartmouth College, and researchers from other institutions have built the first artificial transporter protein that
carries individual atoms across membranes, opening the possibility of engineering a new class of smart molecules with applications in fields as wide ranging as nanotechnology and medicine.
Ionizing radiation is a type of particle radiation in which an
individual particle (for example, a photon, electron, or helium nucleus)
carries enough energy to ionize an
atom or molecule (that is, to completely remove an electron from its orbit).
