3-D AFM Could Advance Understanding of Proteins

Facebook X LinkedIn Email
An advanced 3-D atomic force microscope will allow the study of membrane proteins in conditions similar to those found in the body, an improvement that could lead to increased understanding of proteins on the microscopic level and faster drug therapies. The study of complex proteins that allow information and molecules to pass into and out of a cell has long been restricted by the limitations of one-dimensional force microscopes. Preparation requirements mean that a specimen could not be studied as it would behave in its normal environment. A 3-D atomic force microscope developed...Read full article

    The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation.
    atomic force microscope
    An atomic force microscope (AFM) is a high-resolution imaging and measurement instrument used in nanotechnology, materials science, and biology. It is a type of scanning probe microscope that operates by scanning a sharp tip (usually a few nanometers in diameter) over the surface of a sample at a very close distance. The tip interacts with the sample's surface forces, providing detailed information about the sample's topography and properties at the nanoscale. Key features and principles of...
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
