• Kinked nanopores slow DNA passage for easier sequencing

  In an innovation critical to improved DNA sequencing, a markedly slower transmission of DNA through nanopores has been achieved by a team led by Sandia National Laboratories researchers. Solid-state nanopores sculpted from silicon dioxide are generally straight, tiny tunnels more than a thousand ti more

• Optical Legos: Building nanoshell structures

  Scientists from four U.S. universities have created a way to use Rice University's light-activated nanoshells as building blocks for 2-D and 3-D structures that could find use in chemical sensors, nanolasers and bizarre light-absorbing metamaterials. Much as a child might use Lego blocks to build 3- more

• Argonne scientists reveal secret of nanoparticle crystallization in real time

  A collaboration between the Advanced Photon Source and Center for Nanoscale Materials at U.S. Department of Energy’s (DOE) Argonne National Laboratory has "seen" the crystallization of nanoparticles in unprecedented detail. “Nanoscience is a hot issue right now, and people are trying to create sel more

• Measurement of Nano particles and Proteins
  

  Colloid emulsions in their native environment require particle size determination in high concentration since there are concerns about changes in sample morphology upon dilution eg break up of aggregates. For proteins and other samples with very low concentration and for weakly scattering samples high sensitivity is required. New technologies offer both. more
