Special Issue Information

Dear colleagues,

Nanomaterials have rapidly developed, and attention surrounding their use has increased in recent years. The emergence of various nanomaterials, i.e., nanoparticles, nanograined alloys, and gradient nanostructures, is expected to make it possible for materials with super or very special properties to be applied in unusual practical contexts. There is a wide range of applications for nanomaterials in biochemistry or molecular medicine, fuel cells or metal-ion batteries, flexible electronics, as well as various components related to energy. The physical and chemical properties of nanostructures are determined by their chemical composition and structure and are also affected by the forming process, which is critical for reliability and life in practical applications.

The purpose of this Special Issue is to provide a research forum to report on structure, properties, processing, and applications for nanoparticles and nanomaterials to explore more possibilities to address intractable challenges.

Topics of interest include, but are not limited to, the studies mentioned above. Other relevant studies, such as the design of novel nanostructures or modification of nanoparticles, will also be considered. Research articles and reviews in this area of study are welcome.

We look forward to receiving your contributions.

In this study, Density Functional Theory (DFT) and Density Functional Tight-Binding (DFTB) calculations were used to study two different interfaces of Cu/VSe2 as well as four nanodiodes of VSe2 bulk including/excluding the Cu layer. We calculated the electronic and optical properties of two systems of two Cu/VSe2 in which Cu atoms are positioned on the top and at the corner of the VSe2 monolayer lattice. The electronic band structure calculations revealed that the metallic properties of the VSe2 monolayer did not change with the interface of Cu atoms; however, the peak around the Fermi level (EF) in Cu/VSe2(Top) shifted downward to lower energies. The optical properties showed that in the visible range and the wavelengths related to the interband transition/intraband excitation of Cu atoms, the enhancement of Re(ω) values could be observed for both Cu/VSe2(Top) and Cu/VSe2(Corner) nanostructures, while in infrared/terahertz ranges, less/more negative values of Re(ω) were predicted. Through the effect of Cu atoms on the VSe2 monolayer, the intensity of the peaks in the Im(ω) part of the dielectric constant was increased from 0.2 THz for Cu@VSe2(Top) and 2.9 THz for Cu@VSe2(Corner) instead of the zero constant line in the pure system of VSe2. Refractive index (n) calculations indicated the higher indices at 5.4 and 4.6 for Cu/VSe2(Top) and Cu@VSe2(Corner), respectively, in comparison to the value of 2.9 for VSe2. Finally, DFTB calculations predicted higher current values from I(V) characteristic curves of Au/Cu/VSe2/Au and Ag/Cu/VSe2/Ag nanodiodes concerning two other devices without the presence of the Cu layer.

Infectious laryngotracheitis virus (ILTV), a DNA virus classified as Gallid alphaherpesvirus 1, causes a highly contagious respiratory disease in chickens, leading to significant economic losses and health risks for the poultry industry. The rapid detection of ILTV is essential to control its spread and prevent outbreaks. Traditional diagnostic methods like PCR are costly, require specialized personnel, and delay response efforts. To address this, we developed a point-of-care diagnostic test combining loop-mediated isothermal amplification (LAMP) with DNA nanoprobes on respiratory swabs. LAMP targets the ILTV-glycoprotein E (gE) gene, enabling rapid nucleic acid amplification at 65 °C without extraction, making it suitable for on-site detection. DNA nanoprobes provide a colorimetric readout visible to the naked eye. Gold nanoparticles drive this readout, as their red color, based on localized surface plasmon resonance, persists in the presence of ILTV DNA through DNA-DNA hybridization, ensuring reliable detection. The assay achieved 100% sensitivity and specificity for ILTV-gE, with a detection limit of 200 copies per reaction, allowing for the early identification of infections. The results are available within 45 min, enabling prompt measures to control ILTV spread. Cost-effective and user-friendly, this method enhances disease management and biosecurity in poultry farms.
