2. Bio-pathogen detection system.. 
3. Deliver chemicals in tissue.. 
4. Substrate of SERS.

Proposed outcomes of the study

In the proposed project, we hope to develop a system of glass nano-propellers in the size range from 100 nm to few microns, which are one to two orders of magnitude smaller than existing technologies. The small size is essential for their simultaneous functionality as "active and passive" probes, and will have substantially long sedimentation time, which is essential from the perspetive of suggested applications. From the material aspect, glass (SiO2) provides an excellent platform for conjugating biomolecules via standadrd surface (silane) chemistry methods. A thin ferromagnetic coating on these nano-strucutres is expected to be bio-compatible while allowing them to be propelled (non-locally) by homogeneous magnetic fields in a cork- screw type motion. We beleive that the proposed system of nano-propeller can become an important tool in a variety of biotechnological applications, such as rheological measurements, pathogen sensing techniques and targeted chemical delivery.
