We propose a novel cell stimulation device for the analysis of cell responses to chemical stimuli. In order to deliver chemical substances to target single cells, we developed a microfluidic device having microchannels and apertures in the side wall to subject stimuli to laterally trapped cells. The channels were designed to allow simple flow control with single syringe pump. We demonstrated single cell trapping and culturing of pancreatic β cell with the device. To test its feasibility in cell stimulation assay, intracellular response of the cell to glucose stimulation was demonstrated.

Au Nanowires

Systematic tensile tests were performed on single defect-free 〈110〉 Au nanowires grown by physical vapor deposition while simultaneously recording three-dimensional Bragg peaks using coherent X-rays. The trajectory of three-dimensional Bragg peaks in reciprocal space during tensile testing allowed for measurements of the evolution of strains and rotations of the nanowire, thus sensitively uncovering the full deformation geometry of the nanowire. The transition from elastic to plastic deformation is accompanied by rotations of the nanowire as quantified by analysis of the motion of Bragg peaks, showing the importance of boundary conditions in interpreting nanoscale mechanical deformations.

AbstractThe deformation of Au nanowires of helical multi-shell (HMS) structures and the fcc structure under a tensile external force is addressed by molecular-dynamics simulation. The modified embedded-atom method (MEAM) potential is employed for calculating the interaction between Au atoms. At first, a model nanowire is equilibrated at a specified temperature. Next, the external force in the axial direction is imposed on the Au atoms at the ends of the nanowire. We conclude that the Young modulus of a Au nanowire depends on its atomic structure.
