Nanostructures materials have stimulated broad attention in the past decade because of their potential fundamental characteristics and its promising applications in nano electronic devices. In the present investigation, crystalline boron nanowires (BNWs) were synthesized by vapor liquid solid (VLS) technique and its mechanical properties were studied using a nanomanipulator inside a scanning electron microscope (SEM). Electron beam induced deposition (EBID) method was used to clamp boron nanowire to the AFM tips. The Young’s modulus of the NWs were determined from the buckling instability of NW and computed to be approximately 131.7 ± 14.6GPa. In addition, the nanomanipulation system was used to manipulate nanowire and built a nanoring.
