1Northage, N., Simon, S., Shvalya, V., Modic, M., Juergens, T., Eschborn, S., ... & Walsh, J. L. (2023). Efficient endoscope inner channel surface disinfection using a two-step atmospheric pressure plasma treatment. Applied Surface Science, 623, 156936. In this study, the antibiofilm potential of a two-step disinfection process using cold atmospheric pressure plasma and plasma-activated water is investigated. The combined approach was shown to achieve a 5.72 log reduction in clinically relevant mixed species biofilms in the narrow lumens of a typical endoscope.

Nano letters, 22(23), 9757-9765. Here we demonstrate that surface-enhanced Raman spectroscopy (SERS) can identify bacteria by their genomic DNA composition using nanogold aggregates synthesized by one-step plasma reduction of the ionic gold-containing vaporized precursor. The genomic composition was successfully validated by third generation sequencing using nanopore technology.
3Oberlintner, A., Shvalya, V., Vasudevan, A., Vengust, D., Likozar, B., Cvelbar, U., & Novak, U. (2022). Hydrophilic to hydrophobic: ultrafast conversion of cellulose nanofibrils by cold plasma fluorination. Applied Surface Science, 581, 152276. In this work, it was shown that fluorocarbon plasma treatment improves the hydrophobicity of cellulose surfaces. This was done using the example of nanofibril films treated with CF4 plasma to achieve a conversion from hydrophilic to hydrophobic in less than 10s. Saturation of the water contact angle (about 130o) was achieved after only 30s of treatment.
4Vasudevan, A., Shvalya, V., Košiček, M., Zavašnik, J., Jurov, A., Santhosh, N. M., ... & Cvelbar, U. (2022). From faceted nanoparticles to nanostructured thin film by plasma-jet redox reaction of ionic gold. Journal of Alloys and Compounds, 928, 167155. In this work, a plasma-vapour interaction was used for the simultaneous reduction and deposition of AuNPs from an inorganic precursor (HAuCl4). As surface analyses suggest, the input power of the plasma plays an important role in the reduction efficiency, while a decrease in argon gas flow rate leads to the formation of smaller particles, allowing the tailoring of SERS properties.

Label‐free mycotoxin Raman identification by high‐performing plasmonic vertical carbon nanostructures. Small, 17(49), 2103677. Nanocarbon for SERS. This research shows that high performance plasmonic substrates (analytical amplification factor = 5 × 107) based on plasma grown vertical hollow carbon nanotubes can be used for instant detection of the most toxic mycotoxins. Due to the excellent sensitivity allowing operation at ppb concentrations, it was possible to collect vibrational fingerprints of aflatoxin B1, zearalenone, alternariol and fumonisin.
6Nemanič, V., Zavašnik, J., Shvalya, V., & Žumer, M. (2021). Hydrogen permeability of non-stoichiometric tungsten oxides. Journal of Nuclear Materials, 548, 152860. In this work, I have used Raman spectroscopy to study nanostructures from very different application areas. However, the structure I analysed inspired me to reuse the morphology for SERS application, more specifically for the detection and recognition of military substances.
7Shvalya, V., Filipič, G., Vengust, D., Zavašnik, J., Modic, M., Abdulhalim, I., & Cvelbar, U. (2020). Reusable Au/Pd-coated chestnut-like copper oxide SERS substrates with ultra-fast self-recovery. Applied Surface Science, 517, 146205. In this article, differently tailored nano/micro roughnesses provided excellent light trapping capabilities that resulted in significant improvement in SERS performance. It was found that a chestnut Cu2O substrate activated with an 80 nm thick Au/Pd alloy film exhibited an impressive 3.7-fold increase in Raman signal with respect to the granular structure and about twice the gain of a nanowire- enriched platform decorated in the same manner.

Surface-enhanced Raman spectroscopy for chemical and biological sensing using nanoplasmonics: The relevance of interparticle spacing and surface morphology. Applied Physics Reviews, 7(3). New country – new challenges. This review discusses the major developments over the past decade in surface-enhanced Raman scattering (SERS) and nanoplasmonic materials for sensing applications, focusing on the development of sensors and their use for cancer diagnostics and therapeutic applications, monitoring of kinetic chemical reactions, detection of metal ions in aqueous environments, detection of explosives and hazardous materials, detection of pathogenic bacteria and viruses.

Journal of Materials Chemistry C, 8(29), 9975-9985. A nostalgic work in which we demonstrate for the first time the successful incorporation of metal dopants after synthesis at elevated temperature into a Sn2P2S6 host structure, known as the granddaddy of dichalcogenide ferroelectrics with the formula M2P2X6 (M = metal and X = chalcogen). Using Cu as an example, we show that the integration of dopant atoms into the bulk of an already grown crystal improve the structural, optical, electrical, and ferroelectric properties.

Journal of Alloys and Compounds, 694, 808-814. A study was carried out on the critical behavior of Sn2P2(S1-xSex)6 for x = 0.28 (Lifshitz point) doped independently with Pb and Ge to find a tricritical Lifshitz point. The evolution of the features of the experimental curves (temperature position, shape, thermal hysteresis) was compared with theoretical predictions related to both the stereoactivity of the metal cations in the studied samples and the Blume-Emery-Griffith model with random field effects.
