The main objective of the Project “Optical Nanofabrication in the domain 50 nm – 5 nm” is to valorize the last results of Quantum Optical Lithography with resolution of 2 nm  to 3D optical nanofabrication.
Secondary objectives of NANOFAB Project are the following: i) development of metamaterials (3D photonic crystals) able to improve telecommunications ii) realization of nanochannels and nanoarrays for DNA studies and iii) production of metallic components such as gear for the prototype nanorobots.
Initially, complex 3D structures were produced by stacking multiple 2D layers. The patterns were realized by lithography (optical lithography and Electron Beam Lithography). A new opportunity in 3D fabrication has been started by the development of femtosecond lasers. Materials processing technology by using femtosecond laser irradiation has attracted tremendous interest from the scientific and technological communities. Studies have indicated that diffraction limit creates a major difficulty to obtain 3D structures with dimension smaller than 100 nm. Quantum Optical Lithography broke the diffraction barrier by using new approaches and materials (fluorescent photosensitive glass-ceramics, resist). Fluorescent photosensitive glass-ceramics were successfully tested to produce 3D nanostructures at 2 nm resolution.
The expected results are interesting and the exploitation of this new technique could be economically attractive. A group of novel technologies relating to laser nanomachining using Quantum Optical Lithography will be developed. This advanced materials processing technique opens the door to a new generation of optical devices for telecommunications, nanofluidics and biological sensing.
In present days, optical fiber telecommunications are carried out by infrared lasers. Optical Nanofabrication based on Quantum Optical Lithography with 2 nm resolution is the only technology able to realize at low price and high quality optical components dedicated for optical fiber telecommunications with visible light. This shift of wavelength from infrared to visible light will improve in a major way the performances of telecommunication systems.
US government agencies granted funds to universities and research institutes exceeding billion towards research developing nanodevices for medicine.
Large corporations like Alcatel-Lucent, NEC, Corning, Nippon Telegraph and Telephone invest in optical fiber telecommunications R&D and General Electric, Hewlett-Packard, Northrop Grumman work in the development of medical nanorobots. All these companies could be interested in the application of Optical Nanofabrication in production.
The 1961 classic science-fiction movie Fantastic Voyage movie was about a team of scientists who are shrunk down and sent in a miniature submarine inside the body to repair a blood clot in an ailing colleague’s brain.
The Project NANOFAB will start to convert this dream into reality by producing first metallic components needed for a prototype medical nanorobot.

Development of nanostructures capable of detecting and separating individual molecules and ions has become an important field of research. Particularly, protein-based nanostructures are attractive due to their ability for tunable molecular recognition and ease of chemical modification, which are extremely important factors on various applications. In this project, self-assembly functionalization will be approached, aimed at providing an efficient design for molecular recognition, ion sensing and separation, through new host-guest chemical methodologies, bio-nanofabrication and physicochemical manipulations methods. New crown ether type macrocycles, functionalized cyclodextrins and cyclic peptides will be engineered to work as specific molecular adaptors for the -hemolysin protein, giving rise to hybrid molecular superstructures possessing ion sensing and selectivity properties. The size and functionality of the macrocycles are targeted to ensure the anchorage in the pores and the selectivity of specific host-guest complexation processes. A surface detector array device suitable for use with a biosensor is envisioned, through ink printing nanotechnologies. The device architecture will be formed of a substrate having a surface defining a plurality of distinct bilayer-compatible surface regions separated by one or more bilayer barrier regions. Custom designed nanoscale bilayers containing selected receptors through cyclodextrins derivatives and macrocyclic peptides, self-assembled on different micro-nano arrays surfaces (polymers, Au or Si) will be fabricated. Further engineering of such functionalized nanomaterials based on molecular recognition and host-guest methodologies, in conjunction with flexible and mechanically robust enough substrate platforms, have the great potential for applications such as separation of nanoparticles, sensors, drug delivery, removal of heavy metals from aqueous solutions and chiral separation.
