SISSI - Synchrotron Infrared Source for Spectroscopy and Imaging

Welcome to the SISSI Infrared Beamline

The SISSI infrared beamline at Elettra extracts the IR and visible components of synchrotron emission for performing spectroscopy, microspectroscopy and imaging. The applications cover a wide range of research fields, including surface and material science, biochemistry, forensics, microanalysis, geology, cell biology, biomedical diagnostics, microfluidics, high-pressures, time resolved IR, conservation science, protein folding, chemical kinetics etc.

Research highlights

A new approach based on FTIR spectroscopy to evaluate aging effects on human oocytes

For the first time, FTIR spectroscopy was applied to human oocytes, leading to strong evidences of damage from aging in the gametes of mature women, which could be related to a decline in reproductive function.

New biocompatible CaF2 fluidic devices for FTIRM based on SU-8 resist: a new chemically assisted thermo-mechanical bonding

Mild bonding conditions discussed are compatible with fragile and unconventional materials, but the protocol can be effortlessly extended to quartz, glass or silicon. Since the applicability of the protocol is general it can either impact on the other imaging techniques that require optical paths completely free from any polymeric material, or be applied to the fabrication of multilayer SU-8 devices.

Determination of cell cycle phase in live melanoma cells using SR-FTIRM

The intinsic vibrational details of individual live cells have been successfully exploited to sort in situ each of them according to the progression status, so that FTIRM can be ranked as the first label-free bioanalytical tool to monitor in real time individual cellular response to external agents, exactly knowing the progression state at the time of stress application

Charge distribution in an oxide heterostructure

We employ infrared spectroscopy to address the electrodynamic properties of the LaNiO3/LaMnO3 superlattice series,an heterostructure based on strongly correlated materials. Our results show that charge redistribution across the interfaces is the key to its unconventional properties.

Squeezing THz light into nanovolumes

We show that chains of THz dipole nanoantennas spaced by nanogaps of 20 nm allow retrieving the spectroscopic signature of a monolayer of cadmium selenide quantum dots

Nonequilibrium superconductivity in alkali fullerides

The resonant excitation of the K3C60 fulleride superconductor led to the observation of a transient superconducting-like phase at unprecedented temperatures, far beyond equilibrium Tc

User Area

Proposal Submission

We invite users and collaborators to discuss their proposals with the beamline local contacts well in advance before the submission deadline. This is crucial for improvements in the proposed experimental plan. In a restricted number of cases, when doubts arise about the suitability of your samples or the planned measurements are too close to the microscope resolution limit, it may be possible for you to arrange a test.

Call for proposals

The deadline for proposal submission for beamtime allocation from January 1st to June 30th, 2017 will be September 15th, 2016.

SISSI: new branchline division

We inform the users of the SISSI beamline that from this semester the beamline is formally divided into two branchlines: the Chemical and Life Sciences branchline (SISSI-Bio), coordinated by Lisa Vaccari, and the Material Science branchline (SISSI-Mat), coordinated by Prof. Stefano Lupi.
 

New FTIR Interferometer

The Chemical and Life Sciences branchline of SISSI has recently replaced the VERTEX 70 intrferometer with the in-vacuum VERTEX-70v with FM configuration. The instrument allows covering the FIR/THz and MIR spectral ranges in a single scan.


SAFE Workshop

The SISSI and TeraFERMI teams are organizing the SAFE workshop: "Smaller And FastEr: Infrared and Terahertz Spectral-Imaging at the Nanoscale with Synchrotron Radiation and Free Electron Laser Sources". The workshop will be held at the ICTP (Adriatico Guesthouse) in the 1st and 2nd of December 2016. For more details see:
