«Wavefront Shaping for Microscopic Imaging of Biological Samples»
Περίληψη
“Imaging of biological samples is one of the driving application fields of optical microscopy. Although several other imaging techniques have been developed the simplicity, the effectiveness and the non-invasive nature of optical microscopy are the key factors of its widespread use in Biology.
An important limiting factor for optical microscopy is the scattering of light as it propagates through biological tissue. The inherent random variations of the optical properties, lead to a diffusion dominated propagation that drastically limits the effective imaging range down to 1 mm. On the other hand, recent advances in the spatial modulation of the light beam that illuminates the sample combined with analysis of the detected light distribution have opened the way to beat the diffusion limit.
Τhis PhD thesis was focused on leveraging the concept of the 'opaque lens' by utilizing engineered disorder in photonic structures. This involved developing novel scattering media and their integration with wavefront shaping into imaging modalities. Using this approach, we have reached to the development of a fully functional fluorescence microscope that, in several aspects, outperforms current instrumentation capable of performing in vivo fluorescence microscopy."

«Development of Photonics Based Methodologies for the Assessment of Agricultural Products and Environmental Pollutants.»
Περίληψη
“Quality control and safety of agrofood products are of high importance due to their significant commercial and nutritional value. However, these products are prone to fraud and contamination, posing risks to consumer health. Traditional methods for detecting adulterants and contaminants are accurate but expensive and time-consuming, often requiring specialized facilities. In recent years, the application of optical spectroscopic techniques has emerged as a promising alternative for studying agrofood products. These methods offer rapid analysis, minimal sample pretreatment, and cost-effectiveness. By combining optical spectroscopy with multivariate statistical (machine learning) techniques, it becomes possible to authenticate and control the quality of agrοfood products effectively. The focus of this doctoral thesis is on the development and application of photonics methodologies in two vital agrofood products: olive oil and honey. Α comprehensive study has been conducted on a large number of honey samples using various optical spectroscopic techniques to differentiate botanical origins and predict essential physicochemical parameters. Similarly, extensive research has been undertaken on olive oil to identify varieties and predict chemical compositions accurately. Notably, a novel method, based on fluorescence spectroscopy has been developed for the rapid and cost-effective detection of contaminants such as Polycyclic Aromatic Hydrocarbons and mineral oils. This work, conducted at the Laboratory of Photonics for Agrofood and Environment (Agrophotonics) of the Institute of Electronic Structure and Laser of FORTH, aims to provide practical and affordable solutions for ensuring the origin, safety, and quality of food products.”

«Development and Functionality Control of Advanced Nanocomposite Materials for Mechanical and Electrical Applications»
Περίληψη
This thesis focuses on the research, development, and study of nanocomposite and composite materials with controllably modified characteristics (mechanical, electrical, and physical properties), such as tensile strength, flexural strength, modulus of elasticity, dielectric constant, and conductivity. Advanced nanocomposite filaments were fabricated following a melt mixing process to improve the mechanical and electrical functional properties of three-dimensional (3D) printed structures developed using commercially available Fused Filament Fabrication (FFF) 3D printers.
For this research, novel nanocomposite filaments made of acrylonitrile-butadiene-styrene (ABS), high-density polyethylene (HDPE), and low-density polyethylene (LDPE) matrices were developed with the incorporation of various filler concentrations of graphene nanoplatelets, titanium dioxide, zinc oxide and antimony tin oxide for applications in fused filament fabrication (FFF). The use of nanofillers considerably increased the mechanical response of the polymer matrix. This work aided in developing novel composite polymeric materials not only for 3D printing, but also for their exploitation in large-scale industrial extrusion, offering in some cases more than 50 % increase in tensile, impact and/or flexural strength, when compared to unfilled polymer matrix parts.
Finally, multiple characterization techniques were employed to identify and analyze the structure of the produced specimens, the effect of the filler on the thermal properties of the polymers used and the thermal properties of the composite and nanocomposite materials produced.

Abstract
In this work, we designed and constructed metamaterial structures/antennas and studied their efficiency as sensors. We tested them in different directions to measure their S21 parameters (transmission). Their sensing capabilities were evaluated rigorously against different aqueous solutions enriched with typical agricultural fertilizers.
In the first part of this thesis, we evaluated typical metamaterials structures such as the single-ring resonators on printed circuit boards (PCB), as well as engraved/contemporary structures (CSRRs) on copper plates as efficient sensors against agricultural crop residues and fertilizers.
In the second part of this work, we fabricated metamaterial-based antennas and measured the S11 (reflection) coefficients against typical agricultural pollutants.
The objective of this study is to develop a real-time sensor for agricultural purposes that is easy to manufacture and user-friendly. Our experimental data clearly demonstrate the potential of metasurfaces as effective sensors for detecting water pollution.
