We start with two examples
Magnetic Nanoparticles and Medical Imaging Electrolithography
Nanoparticles for Bio-Imaging: Magnetic Resonance Imaging and Fluorescence Imaging Relaxivity Nanoparticles in MRI: not good Nanoparticles in MRI: good
Nanoparticles for Bio-Imaging: Magnetic Resonance Imaging and Fluorescence Imaging Effect of Nanoparticle Arrangement on Graphene Oxide Magnetic Nanoparticles Graphene Oxide Sheet μ is magnetic moment of the nanoparticle, Ng is the number of nanoparticles in an agglomerate Best arrangement : Graphene Oxide partially reduced-still hydrophilic and Coupling of magnetic moments between agglomerated nanoparticles
Nanoparticles for Bio-Imaging: Magnetic Resonance Imaging and Fluorescence Imaging Core-Shell Geometry Exchange-coupled magnetic nanoparticles for efficient Hyperthermia and Imaging MnFe2O4 Fe3O4 Geometry MnFe2O4-Fe3O4 Relaxivity Value 184 mm-1s-1 CoFe2O4 96 mm-1s-1 MnFe2O4 83 mm-1s-1
Nanoparticles for Bio-Imaging: Magnetic Resonance Imaging and Fluorescence Imaging Core-Shell Geometry Nanoparticles for Multimodal Bio-Imaging 0.2 µm Co-Ferrite nanoparticle Agglomerates in ZnO capsule High Value of Proton Relaxivity obtained from the Agglomeration and magnetic coupling of CoFe2O4 particles Fluorescence images of Hela cells incubated with CoFe2O4-ZnO nanoparticles.
Magnetic Nanoparticles and Medical Imaging Electrolithography
Liquid Electromigration in Very Thin Films Appliction of electric current through thin film of Cr leads to its melting and flow in radially symmetric fashion: Liquid Electromigration Cathode Can this idea be used to develop a lithography technique?
Basic Idea Behind Electrolithography A static quill produces a large dot whereas a traversing quill creates myriads of shapes with sharp edges http://cliparts.co/clipart/ http://www.dreamstime.com/ 50 µm And just like writing with a quill, we need to learn how to control and optimize writing with an electrode!
Optimized Steps of Electrolithography Process Placing a polymer (PMMA) layer in between metal layer and the substrate allows deposition of thick films
A Few Example Fabricated Linear structures Narrowest Au line drawn by AFM tip Ti line drawn in probe station Parallel Ti lines drawn by AFM tip Scalable a few tens of nanometres to a few micrometres Sub-100 nm resolution under ambient conditions Repeatable and continuous with no effect on earlier scribed patterns
Curved Lines and Direct Mask Printing on Transparent Glass Cr on Si Cr on glass Transparent opening Curved as well as closed shapes can also be drawn Masks can be fabricated by removal of opaque metallic layer deposited on transparent substrate

There are some, only some, things under a researcher s control lab, equipment, students. Funding programs exists for scientific research and technology development / demonstration. Taking it from here in the lab to there in the market needs many further steps. Need for strong backing: Institutions: Research Park at IIT-M, Society for Innovation and Development at IISc Funding: Angel investors, Venture capital firms, Investment banks Management: Manufacturing, Manpower, Marketing
India Innovates
Make in India
