Nanotechnology is an interdisciplinary field of science and technology. It deals with all fields of science-biology, physics, and chemistry. This application is a comprehensive guide through various aspects of nanotechnology. We believe this application is much helpful for learners to know about various nanotechnologies like Characterization Techniques-SEM, TEM, XRD, XRF, FTIR, STM, AFM, DLS, Nano materials -Carbon Nanotube, Fullerenes, Nanowires, Nanosensors, Nanorobots Synthesis Methods- Solgel, Mechanical Grinding, Spray Pyrolysis, CVD, MBE, PVD, PLD, Sputtering MEMS,NEMS. And Lithography-Photolithography, Electron Beam Lithography, X-Ray Lithography, Euv Lithography, Nanoimprint Lithography, Ion Beam Lithography, FIB Lithography, Stencil Lithography, AFM Lithography.
