The quest for suitable micro- and nano-structure materials that can act as optical waveguides for interconnects in integrated photonic devices has accelerated the research in optical nanowires and nanotubes of different origins. In our research we investigate optical properties of various bio-organic materials (such as, amino acids, peptides and proteins), and exploit their unique features for developing multifunctional biochips, implantable bio-photonic devices, optical waveguides, and other tools for medical diagnosis and therapy. We employ  nanotechnology experimental methods (such as, XRD, FTIR, SEM, AFM, Nano-Fountain Pen, Raman, FL/OA, SHG microscopy and more) as well as simulation methods (FDTD).
