Special Issue Information

Dear Colleagues,

The design and processing of new interfaces with specific tailored characteristics is of interest to be exploited for advanced applications in nanotechnology that include medicine, sensoristics, microfluidics, catalysis, and environmental science. Therefore, novel induced topographical, chemical, and structural nanofeatures or hierarchical micro- combined with nanofeatures can be used to enhance and impart multifunctional properties of that surface to meet the requirements of the specific applications.

This issue focuses on the fundamentals of multifunctional nanostructured interfaces and their associated technologies, including versatile technologies, which can be used to obtain multifunctional 2D and 3D micro- and nanotextured interfaces for a wide range of applications in the sensing, photocatalytic, and bioengineering areas. We invite researchers to contribute original research articles as well as review articles that investigate the interface processes involving physical and chemical modifications that can be directly correlated and influencing the aimed applications in the biorelated, sensing, and technology fields.

Potential topics include but are not limited to the following:

  • Nanofabrication and surface texturing methods, including coatings and surface and interface chemical and physical engineering, modification, and functionalization, including characterization and analysis;
  • Smart and/or functional nanointerface nano- and micropatterning of biological compounds, natural and synthetic polymers for bioplatforms, microfluidics, and sensors;
  • Polymer, hybrid, and composite materials: 2D and 3D surface structuring for cell interaction and behavior studies;
  • Cell–biomimetic hierarchical nano- and microstructured interfaces;
  • Design of multifunctional nanocomposites and nanohybrids interfaces for tissue repair and drug mediated release;
  • Design of multifunctional nanohybrids and nanocomposites for photocatalytic/environmental applications;
  • Design of multifunctional nanohybrids and nanocomposites for chemical sensors and or biosensors;
  • Tuning materials nano- and/or nano–microarchitectural characteristics for sensing, biorelated, and environmental applications.

Development of Pd/TiO2 Porous Layers by Pulsed Laser Deposition for Surface Acoustic Wave H2 Gas Sensor

The influence of sensitive porous films obtained by pulsed laser deposition (PLD) on the response of surface acoustic wave (SAW) sensors on hydrogen at room temperature (RT) was studied. Monolayer films of TiO2 and bilayer films of Pd/TiO2 were deposited on the quartz substrates of SAW sensors. By varying the oxygen and argon pressure in the PLD deposition chamber, different morphologies of the sensitive films were obtained, which were analyzed based on scanning electron microscopy (SEM) images. SAW sensors were realized with different porosity degrees, and these were tested at different hydrogen concentrations. It has been confirmed that the high porosity of the film and the bilayer structure leads to a higher frequency shift and allow the possibility to make tests at lower concentrations. Thus, the best sensor, Pd-1500/TiO2-600, with the deposition pressure of 600 mTorr for TiO2 and 1500 mTorr for Pd, had a frequency shift of 1.8 kHz at 2% hydrogen concentration, a sensitivity of 0.10 Hz/ppm and a limit of detection (LOD) of 1210 ppm. SAW sensors based on such porous films allow the detection of hydrogen but also of other gases at RT, and by PLD method such sensitive porous and nanostructured films can be easily developed.

Title: Self-assembly of magnetic nanoparticles in ferrofluids on different templates investigated by neutron reflectometry
Authors: Apurve Saini; Max Wolff; Julie Borchers; Joseph Dura
Affiliation: Uppsala University, Division for Materials Physics, Uppsala University, 75120 Uppsala, Sweden NIST Center for Neutron Research, 100 Bureau Drive, Gaithersburg, 20899-6102, USA
Abstract: This article reviews the self-assembly of magnetite nano-particles onto solid surfaces. We focus on neutron reflectometry studies providing information on the density and magnetisation profiles of buried interfaces. Specific focus is given to the near-interface wetting layer and examples of magnetite nanoparticles on a hydrophilic silicon crystal; one coated with (3-Aminopropyl)triethoxysilan, and finally one with a magnetic film with out-of-plane magnetization.
