We report a method of the construction of a sub-diffraction limit 3D focal spot array by a 4Pi focusing system consisting of two high-numerical-aperture (NA) objectives. The approach can be achieved ...

We previously reported a 3D printed ultra-wide band (UWB) Balanced Antipodal Vivaldi Array (BAVA) with 104 linearly polarized antennas on a hemisphere. In this work, we explore how this concept can be ...

DNA nanotechnology has recently provided a novel approach for developing safe, biocompatible, biodegradable, non-immunogenic, and non-toxic drug delivery systems. DNA nanostructures have numerous ...
