Motor proteins are molecular motors, which efficiently convert chemical energy stored in ATP into mechanical work, demonstrating the feasibility and applications of nanoscale engines. We are designing hybrid, biomimetic nanodevices and materials based on the motor protein kinesin by merging biotechnology with micro- and nanofabrication. In previous years, we presented prototypes of molecular shuttles (a nanoscale transport system) [1-3], and a piconewton forcemeter , and introduced a novel surface imaging method based on self-propelled probes .
Now we can report on measurements of the specifications of our devices, for example the clearance of molecular shuttles, which require non-destructive distance measurements with nanometer accuracy. These measurements aid the design process, and establish the performance limits of hybrid devices.
We will also present our recent progress in the design of motor protein-based nanodevices (e.g. described in ), which demonstrate the promise of molecular-scale motors for nanotechnology.
