Silicon nano-needles with specific attachment point for visualization of protein movement

We have fabricated silicon nano-needles of 140 nm diameter and 1.5 /spl mu/m length for visualization of motor protein movement. Due to the geometry of the needles, they are ideal to amplify and visualize angular movement. To enable a well-defined and highly localized needle-protein connection, a specifically functionalized attachment point was included… CONTINUE READING
