Graphene coated microtiter plates for biological analysis: Fabrication and integration of these ready made graphene coated microtiter plates will be discussed along with the transfer of the whole process to sticky slides. Inflammatory response and stem cell differentiation studies are being carried out using these substrates.

Graphene as a window for TEM (Transmission Electron Microscopy): Conventional Silicon nitride membranes have been replaced by graphene for live TEM imaging. Live imaging of water within fabricated graphene nanoscrolls under TEM has been demonstrated for the first time giving a feasibility to study the water dynamics at nanoscale. Graphene nanoscrolls fabrication on a TEM grid and the results associated will be presented.

3D graphene and substrate free transfer of CVD graphene will also be discussed in brief.

Short CV: Venkata Raghavendra S.S. Mokkapati (Raghu) acquired his phd in "Micro and nanofluidic devices for single cell and DNA analysis" from Delft University of Technology, The Netherlands, followed by a postdoctorate in "Disposable microfluidic devices" from Austrian Institute of Technology, Vienna. Before moving to Sabanci University he worked as a Research Fellow at National University of Singapore, Singapore, on exploring biological applications of graphene.
