DESCRIPTION

The 2D Materials and Devices group (2DMD) research focus on CVD growth, transfer and device fabrication, using 2D materials, clean-room technology, and Raman imaging for structural characterization. Particular attention is given to biosensing devices, where immuno-assays and DNA sensors based on graphene liquid-gate FETs were developed. The devices specificity for particular biomarkers is achieved by functionalization of the graphene channel. DNA detection based on electrochemical arrays of graphene microsensors is achieved. The group is running collaborative projects on the fabrication of optoelectronic devices: a photodetector based on Van der Waals stacking of 2D materials (with LANASC and UMinho), and photocathodes that can potentially realize un-assisted solar water splitting by coupling tandem amorphous silicon solar cells with high efficiency hydrogen evolution electrodes (with NESC and IPV-5 Jülich). The 2DMD group research interests include the study of single photon emitters from controlled defects in h-BN (with Nanophotonics dept.) and the fabrication of graphene plasmonic devices that operate in the sub-mm wavelength range.

RESEARCH PROJECTS

028114:  Total Budget: €239.924,23. Duration: 01 July 2018 – 30 June 2021.
This project’s main idea is to develop a new spectroscopic technique based on tunable plasmonics in graphene, by exploring the polarization dependent interaction of small biomolecules with terahertz (THz) radiation. Graphene is widely recognized as an ideal platform for strong light matter interactions due to its excellent plasmonic response in the mid-to-far infrared spectral range. In addition, the plasmonic response of graphene is highly tunable in real time using electrostatic gating. Fundamental structural features of peptides that are critically important for their functions can, in principle, be probed by polarization dependent spectroscopy in the THz range, as described in a recent simulation study, which also explicitly noted that THz chiroptical spectroscopy has not yet been demonstrated experimentally. The innovative aspect of this project is, therefore, to develop devices that realize this predicted technique for molecular analysis using spectroscopic plasmonics. Two different architectures will be developed for implementing strong light-matter interaction between graphene and biomolecules. In one approach, micrometer wide ribbons of graphene, patterned by optical lithography, act as the active plasmonic medium. The second approach consists of transferring a continuous graphene sheet onto a grating of high dielectric contrast provided by alternating lines of SiO2 and Al2O3 on a high resistivity silicon wafer. Both architectures are based on theoretical simulations developed and performed by the team members, who have recently published their studies in a book about graphene plasmonics. Specifically, the two device architectures are modeled using full electrodynamics calculations, which are faster and perform better than the conventional time domain integration of Maxwell’s equations. The high sensitivity of surface-based detection methods, including conventional noble metal plasmonics, makes them particularly advantageous for analyzing small quantities of biomolecules. Being a 2D material, graphene is a natural choice for implementing surface-based sensors.
Furthermore, the unique properties of the electromagnetic coupling of molecular excitations to surface plasmons in graphene open possibilities for extending the analytical capabilities of these sensors beyond the current state of the art for label-free measurements. Real-time tuning of plasmon resonances in graphene will enable spectroscopic, i.e., more specific, detection of biomolecules in presence of solvent and other background signals. This specificity will be enhanced by structural, e.g., chiral, signatures enabled by polarization dependent THz measurements. The specificity and information content of these measurements will be further enhanced by taking advantage of the high-intensity tunable broadband THz excitation produced by the two color air plasma method and of the time-resolved pump probe capabilities of the THz source and spectrometer to be developed in this project.
Main Goal: The idea of this project is to explore plasmons in graphene for a new spectroscopic technique. This technique covers the THz and the mid-IR. Graphene plasmons exist in these spectral ranges in which noble-metal plasmons are not available. The excitation of surface plasmons in graphene produces huge resonances in the extinction spectrum of the material. These resonances amplify tremendously the absorption signal due to molecules deposited on graphene and therefore can be used as a tool for the spectral identification of small quantities of analytes, down to a monolayer. The absorption of the analytes is due to their rotational and vibrational modes. The signal due to the absorption of the analytes is superimposed on the plasmonic resonance and appears as dips in the resonance signal. Depending on the rotational or vibrational excited energy levels, the dips are located at different positions, thus allowing an amplified spectroscopic signal.

Portugal, and in particular the north region, is a leading producer of wine in the EU, with one of the highest numbers of DOP and IGPs in Europe, including world-known Port and Douro wines. Among common wine adulteration, the use of different grape varieties from the ones authorized by the PDO, or the use of more than one variety in wines labelled as monovarietal, are one of the issues of higher concern for producers and authorities.
DNA based analysis have become a very useful instrument on food and environmental analysis. DNA analysis is of high interest as well for varietal discrimination of grapes, wines, musts, and grape juice, due to the high specificity allowed by the use of DNA sequences, and the possibility of amplifying such DNA markers by PCR and other amplification strategies, and therefore obtaining higher sensitivity. Despite its advantages for grape variety identification, DNA analysis has not been extensively used by control laboratories, due to some drawbacks for their practical implementation. Several developments in the last years are being directed towards the improvement of DNA based analysis in order to simplify, miniaturize and reduce both the time and price of analysis with increased performance, to develop devices and methodology to be effectively used by control laboratories. Among such improvements, several sensors have been developed with promising characteristics, among them, field-effect transistors (FETs) allow to achieve high sensitivity, specificity and rapid measurement without the need of labelling, making them excellent candidates for wine/grape authenticity analysis. Likewise, there has been a strong interest in developing portable point-of-care devices that can be used in resource-limited settings, such as remote regions, farms or cultivars. Several approaches towards micro total analysis system (μTAS, or lab-on-a-chip) have been developed, which provides a significant improvement in performance. However, to our knowledge and despite of their clear advantages, no commercial μTAS are currently available and validated for DNA analysis in wine or food commodities.
Main Goal: The main objective of the project is the development, test and in-house validation of a miniaturized DNA sensing device for varietal discrimination of grapes, wines, musts, and grape juice in order to ensure the authenticity of wine from Port and Douro DOP. With this objective the participating teams will combine their expertise for the development of a miniaturized analytical device composed of 3 modules namely: a DNA extraction and purification module, an isothermal DNA amplification module, and a DNA Biosensors based on field-effect transistors (FETs) made using single layer graphene (SLG) for varietal discrimination. The integrated device will be in-house validated with different complex matrixes including grapes, wines, musts, and grape juice.

The modifications of the fluorescence lifetime by the presence of fluorescence quenchers can be used to increase the axial resolution of fluorescence lifetime imaging microscopy (FLIM). The axial spatial range of the quencher material depends on its refractive index (RI), so materials with different RI can be explored in order to improve and modify the imaging axial range and axial resolution of FLIM. The main goal of the project is to optimize the FLIM technique for different resolutions and distance ranges to study different biological processes. Applications range from DNA detection to the time lapse super resolution imaging of live cells to track specific molecular biological processes in real time.
Main Goal: Optimization of a Fluorescence Lifetime Microscopy Imaging (FLIM) technique for axial super-resolution using various functional substrates and its application for biosensing and bioimaging.

The market awareness to graphene and related materials has been growing steeply, as a result of promising results obtained in an experimental context. However, the application of these materials at an industrial scale has not yet been attained yet due to a number of constraints of the available production technologies, which can be generally resumed as an inability to simultaneously produce graphene in quantity, quality, and price, according to the needs of the industrial sector. Acknowledging this gap between the existing technologies and the industry needs, Graphenest has designed and developed an innovative technology, supported by a graphite exfoliation method in liquid phase using ultrasonic cavitation. Duly tested/validated at a laboratory scale, through the development of a prototype, Graphenest’s technology now needs further demonstration at a pre-industrial scale (and full industrial, at a later stage).
The GNESIS project emerges in this context, aiming at (i) assuring the scale-up of Graphenest’s technology into a pre-industrial scale and (ii) demonstrating the application of the graphene-based materials obtained from the referred technology in three different application areas, namely: anti-corrosion paints; polymers with electromagnetic shielding; and tactile screen electrodes. The GNESIS project will be promoted by a full consortium consisting of two companies with strong R&D skills – i.e., Graphenest (project leader) and Displax – as well as three entities from the Portuguese Research and Innovation System – i.e., the International Laboratory of Iberian Nanotechnology, University of Aveiro and University of Minho. In addition, the project will be attended by three national associated business partners – i.e., Bosch, CIN and Galp Energia – and an international one – the Chinese company Zhejiang Light-Tough Composite Materials.
