Multispectral Imaging Measurements

We have the possibility to implement quantitative detection and mapping of chemical characteristics through spectral imaging using an XPECAM X01 Multispectral imaging system, equipped with a CMOS Monochrome sensor, covering 30 spectral bands, operating from 350 - 1200 nm, with a spatial resolution of 5M pixels.

Horiba LabRAM HR Evolution Raman microspectrometer

A Horiba LabRAM HR Evolution Raman microspectrometer (30 - 4000 cm-1), with open space microscope, offering a large free space under the objective turret. Thus, we can use large sample holders like cryostats, high temperature cells, high pressure cells, or just large samples. In order to get high stability, the sample stage is hard coupled to the LabRAM HR, while focusing is achieved by adjusting the height of the microscope objectives instead of the sample stage. This microscope offers all the functions of the standard microscope.

The objectives of the group are:

  • Photoscience applications – Photonics in Agrofoods and Environment

We apply our know-how from the basic research studies for investigations in several applied fields such as:

  • Mass spectrometry in combination with laser induced break down spectroscopy (LIBS) for the analysis of the composition and structure of cultural heritage materials  (in collaboration with the group working in the cultural heritage projects).

  • Nanostructured materials produced by laser ablation in liquids in conjugation with biomolecules.

  • Uv-Vis and fluorescence spectroscopy to control the quality and the origin of agrofoods.

  • Laser spectroscopy for environmental studies aiming in detecting traces of greenhouse gases in the environment due to agricultural applications.

 

Research Topics

The research targets the understanding of  the formation mechanisms, the stability, the structure (geometric and/or electronic) and the properties (optical activity, chemical reactivity, catalytic activity) of clusters and free biomolecules and also the study of nanostructured materials made out of clusters.

At the Photonics for Agrofoods and Environment laboratory, we employ an alternative approach for the quick monitoring of the characteristic substances contained in food samples, with little or no processing. 

We rely on our expertise in the area of the interaction of light with matter and the development of specialized optical spectroscopic analysis methods (such as light absorption and fluorescence techniques). This way, we can record the optical spectrum that is the characteristic "fingerprint" and reflects the chemical composition of a sample. Different samples have a different fingerprint and the detected differences or similarities are used for:

  • identification,
  • origin and quality control

We focus on spectroscopic methods such as UltraViolet/Visible, Near Infrared, Fourier Transform Infrared (FTIR), Fluorescence, Laser induced Fluorescence (LIF), Time Resolved Florescence, Raman and Laser Induced Break Down Spectroscopy (LIBS). These techniques are quick and much "cheaper" than the time-consuming and costly conventional analytical techniques.

Our technology is used for:

  • Distinction of varieties of several agrofoods products (wine, oil, honey, milk, etc.)
  • Monitoring of wine maturation in relation to time and kind of barrel
  • Quality control of products
  • Detection of adulteration
  • Application of laser spectroscopic techniques for the detection of specific chemical substances in foods (contaminants, plasticizers, pesticides ...)
  • Creation of a database for the prominence of local varieties and the characterization of their geographical origin
Application of innovative optical methods to improve the quality of Greek wine through monitoring and control of winemaking parameters.
Development of an optical spectroscopy system prototype for fuel adulteration detection
Innovative technologies for climate change mitigation by Mediterranean agricultural sector
Quality and authenticity of the end products of olives (Edible olives– olive oil)
