Interferometric scattering microscopy with polarization selective dual detection scheme: capturing the orienational information of anisotropic nanometric objects
2018 BPS18
Single-particle tracking is a powerful technique to reveal an underlying principle of microscopic phenomena. Here we report an optical microscopy technique, polarization-selective interferometric scattering microscopy that enables us to capture rotational as well as positional information of nano-scale objects. This technique grants all the merits of interferometric scattering microscopy and provides a further advantage of the capability of determining the orientation of single nanoscopic objects in a straightforward and facile way.
We anticipate that this technique would be of critical use in rotational tracking of a single anisotropic particle or biological system in the nanoscopic world.
