چکیده

Gold nanorods are widely known for their photothermal properties to treat solid tumors. Our work demonstrates the unrealized capacity to image these reagents in liquid at high resolution using Transmission Electron Microscopy (TEM). Here we perform the first atomic measurements of functionalized nanorods in solution while visualizing their dynamic behaviour with TEM.

Note: High-speed Z tip scanner with screw cantilever holding mechanism for atomic-resolution atomic force microscopy in liquid.

High-speed atomic force microscopy has attracted much attention due to its unique capability of visualizing nanoscale dynamic processes at a solid/liquid interface. However, its usability and resolution have yet to be improved. As one of the solutions for this issue, here we present a design of a high-speed Z-tip scanner with screw holding mechanism. We perform detailed comparison between desig...

Studies of the dynamics of biological macromolecules using Au nanoparticle-DNA artificial molecules.

The recent development of graphene liquid cells, a nanoscale version of liquid bubble wrap, is a breakthrough for in situ liquid phase electron microscopy (EM). Using ultrathin graphene sheets as the liquid sample container, graphene liquid cells have allowed the unprecedented atomic resolution observation of solution phase growth and dynamics of nanocrystals. Here we explore the potential of t...

Dielectrophoretic force microscopy of aqueous interfaces.

A novel scanning probe microscopy technique has allowed dielectrophoretic force imaging with nanoscale spatial resolution. Dielectrophoresis (DEP) traditionally describes the mobility of polarizable particles in inhomogeneous alternating current (ac) electric fields. Integrating DEP with atomic force microscopy allows for noncontact imaging with the image contrast related to the local electric ...

Transport of Electrons in Atomic Liquids in High Electric Fields

To describe the transport properties of hot electrons in high electric fields, a theory for the scattering of excess electrons in atomic liquids with high atomic polarizability is proposed. The theory is based on the variable phase method and it does not require information about the short-range part of the electron-atom potential. The scattering of electrons by density fluctuations in a liquid...

An investigation of neutron direct damages at energies of 0.1-2 MeV on the DNA molecules with atomic structure deduced using Geant4 toolkit

This study proposes a method to estimate RBE of fast neutrons using Monte Carlo simulations. This approach is based on the combination of an atomic resolution DNA geometrical model and Monte Carlo simulations for tracking particles. Atomic positions were extracted from the Protein Data Bank. The GEANT4 code was used for tracking the secondary particles generated by fast neutrons during their in...
