Abstract:
RESONANO proposes to bring optical imaging beyond the current state-of-the-art by integrating
imaging at the resonance with an existing multimodal microscope. More precisely, the project
scope is to extend the current multimodal system with chemical fingerprinting in a threefold
approach: (1) tunable AFM tip for scanning near field optical microscopy (SNOM) investigations;
(2) module capable of determining the resonances of different samples in visible and infrared; (3) module for upright SNOM (u-SNOM) with 3D capabilities. The tunable AFM tip which the
RESONANO intends to develop will be based on a metallic-semiconductor composite structure
with optically tunable effective size, which translates in variable size-dependent resonant
wavelengths. A system capable of determining resonance frequencies for light absorption
(RFLA) will be built allowing the RESONANO system to use sample specific wavelengths for
imaging. An extension of current SNOM imaging modalities will be developed in an upright
SNOM implementation. RESONANO will be the most complete multimodal system and will
offer a complete image regarding the samples with information about optical properties of very
different kind of structures (biological, semiconductor, photonics and optoelectronics materials,
nanoparticles, etc.).The main objective of the project (RESONANO) is to develop an innovative nanoscope without fluorescent markers, based on the absorption resonances of the structures, using low level laser power and to integrate it into the existing multimodal system (MMS) within CMMIP-UPB. This new nanoscope will work with laser radiation at resonant wavelengths, being able to provide complementary information about the optical properties of surfaces and volumes of a wide range of samples (biological, semiconductor, photonic and optoelectronic, semiconductor and metallic nanoparticles, etc.).

– Integration of the RFLA system in the existing multimodal microscopy system within CMMPI-UPB;
– The realization of a double nanoscope based on near field, which would work in the microscope modes without aperture and inverted microscope.
– Microscopy images with a contrast superior to current techniques by using the nearfield signal generated at plasmon resonance frequencies;
– Correlated imaging by using far field and near field imaging;
– Development of High Throughput Images Analysis using Automation and Image Processing;
-RESONANO will deliver an integrated solution for the characterization of biological, semiconductor, photonics, optoelectronics materials and nanoparticles in the purpose of acquiring information as complete as possible about the optical properties of the sample;
