	Abstract = {Mechanical properties of individual rolled-up SiGe/ Si microtubes are investigated experimentally using nanorobotic manipulation. By applying bending loads, individual SiGe/ Si microtubes demonstrate various deformation modes with increasing bending angle. Remarkably, the tested microtubes resist fracture even when bent back onto themselves (180° bending angle). Axial compression tests of microtubes with different turns are also performed. Among those tubes, 1.6-turn rolled-up SiGe/ Si microtubes show typical Euler buckling behavior when the load is larger than a critical load, which can be estimated by the Euler formula for columns.}
