    High Resolution Image Download MS PowerPoint Slide The green synthesis of bioactive nanomaterials is becoming more attractive in various fields like biotechnology, pharmaceuticals, cosmeceuticals, etc. In this study, bacterial cellulose–silver and bacterial cellulose–gold bionanocomposites were obtained through an environmentally friendly and low-cost method without using additional reducing agents. In the first step, the bacterial cellulose, a byproduct from kombucha production using a symbiotic culture of bacteria and yeast (SCOBY), was purified using an alkaline solution. In the second step, the purified bacterial cellulose (SBC) was used to obtain silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs) on the bacterial cellulose matrix, starting only from metal precursors in different media: water, black tea, and kombucha. Gold and silver nanoparticles were obtained on cellulose fibrils in all media, even in water, indicating the reducing role of cellulose. The morphology and structural features of the noble metal nanoparticles/bacterial cellulose nanocomposites (AgNPs/SBC and AuNPs/SBC) were investigated. Scanning electron microscopy (SEM) images show nanoparticles with an irregular shape with dimensions ranging from a few nanometers up to 70 nm, depending on the synthesis medium. TEM analysis revealed mostly quasi-spherical nanoparticles distributed along the surface of the cellulose fibers or within the interfibrillar pores. All nanoparticles are well crystallized and generally formed from more than two nanocrystallites, except AuNPs obtained in kombucha which are monocrystalline. XRD analysis shows the characteristic diffractograms of Iβ cellulose allomorphs and confirms the formation of crystalline AgNPs and AuNPs. The antioxidant capacity tests determined that the best activity was registered for the AgNPs/SBC composites obtained in kombucha and fresh black tea. The antimicrobial potential was evaluated against the Gram-negative bacteria Escherichia coli and the Gram-positive bacteria Staphylococcus aureus and Listeria monocytogenes . Cellulose–silver and cellulose–gold nanocomposites showed increased antimicrobial activity compared with raw SBC, especially in the case of kombucha medium for green synthesis. The highest antioxidant activity, determined by DPPH and ABTS assays, was obtained for AgNPs/SBC produced in kombucha and fresh black tea. Based on the results, cellulose–silver and cellulose–gold nanocomposites could be considered as bioactive materials for multiple practical applications, such as the medical field and food packaging.
  • Thermally Induced Polymorphic Changes in Poly(vinylidene Fluoride) Thin Layer Investigated Using Micro-Raman Spectroscopy
    Munizer Purica, Florin Constantin Comanescu, Violeta Dediu
    Coatings, 2024
    Poly vinylidene fluoride (PVDF) is a versatile polymer that shows polymorphism, and most of its applications are based on its piezoelectric properties given by its polar crystalline phases. Increasing the polymer’s polar β-phase content has been a major pursuit in material science. We present the results on the evolution of induced polymorphic changes of PVDF through thermal treatment and the presence of the nano-ZnO with different morphologies. Three types of samples—a PVDF pure layer, PVDF:ZnO nanoparticles (NPs) and PVDF:ZnO nanorods (NRs)—were subjected to stress by heating at different temperatures from 50 °C close to melting temperature, 170 °C. The changes in PVDF–ZnO composite layers were investigated in situ using an experimental setup consisting of a high-resolution micro-Raman spectrometer and a thermo-electric cell. The ZnO NPs and NRs added in PVDF lead to obtaining a PVDF nanocomposite in which the intensity of the β phase is much higher than that of the α phase: intensities ratio Iβ(840.6 cm−1)/Iα(798.9 cm−1) > 5.56. The phase is stable up to 150 °C, and with the increase in temperature to 170 °C, the β phase passes to a lower crystallinity α phase with a large amorphous content highlighted by the 400–700 cm−1 and 800–1000 cm−1 regions without Raman peaks.

    The use of a combination of nanoparticles as antimicrobial agents can be one strategy to overcome the tendency of microbes to become resistant to antibiotic action. Also, the optimization of nano-photocatalysts to efficiently remove persistent pollutants from wastewater is a hot topic. In this study, two composites ZnO/Au (1% wt.) and ZnO/Ag (1% wt.) were synthesized by simple aqueous solution methods. The structure and morphology of the r nanocomposites were analyzed by structural and optical characterization methods. The formation of AuNPs and AgNPs in these experiments was also discussed. The antimicrobial properties of ZnO, ZnO/Au, and ZnO/Ag nanomaterials were investigated against Gram-negative bacteria (Pseudomonas aeruginosa) and Gram-positive bacteria (Staphylococcus aureus). The results showed an increase of 80% in the antimicrobial activity of ZnO/Au against Pseudomonas aeruginosa compared with 30% in the case of ZnO/Ag. Similarly, in the case of the S. aureus strain tests, ZnO/Au increased the antimicrobial activity by 55% and ZnO/Ag by 33%. The photocatalytic tests indicated an improvement in the photocatalytic degradation of methylene blue (MB) under UV irradiation using ZnO/Au and ZnO/Ag nanocomposites compared to bare ZnO. The photocatalytic degradation efficiency of ZnO after 60 min of UV irradiation was ∼83%, while the addition of AuNPs enhanced the degradation rate to ∼95% (ZP2), and AgNP presence enhanced the efficiency to ∼98%. The introduction of noble metallic nanoparticles into the ZnO matrix proved to be an effective strategy to increase their antimicrobial activity against P. aeruginosa and S. aureus, and their photocatalytic activity was evaluated through the degradation of MB dye. Comparing the enhancing effects of Au and Ag, it was found that ZnO/Au was a better antimicrobial agent while ZnO/Ag was a more effective photocatalyst under UV irradiation.
  • Trends in Photothermal Nanostructures for Antimicrobial Applications

    International Journal of Molecular Sciences, 2023
    The rapid development of antimicrobial resistance due to broad antibiotic utilisation in the healthcare and food industries and the non-availability of novel antibiotics represents one of the most critical public health issues worldwide. Current advances in nanotechnology allow new materials to address drug-resistant bacterial infections in specific, focused, and biologically safe ways. The unique physicochemical properties, biocompatibility, and wide range of adaptability of nanomaterials that exhibit photothermal capability can be employed to develop the next generation of photothermally induced controllable hyperthermia as antibacterial nanoplatforms. Here, we review the current state of the art in different functional classes of photothermal antibacterial nanomaterials and strategies to optimise antimicrobial efficiency. The recent achievements and trends in developing photothermally active nanostructures, including plasmonic metals, semiconductors, and carbon-based and organic photothermal polymers, and antibacterial mechanisms of action, including anti-multidrug-resistant bacteria and biofilm removal, will be discussed. Insights into the mechanisms of the photothermal effect and various factors influencing photothermal antimicrobial performance, emphasising the structure–performance relationship, are discussed. We will examine the photothermal agents’ functionalisation for specific bacteria, the effects of the near-infrared light irradiation spectrum, and active photothermal materials for multimodal synergistic-based therapies to minimise side effects and maintain low costs. The most relevant applications are presented, such as antibiofilm formation, biofilm penetration or ablation, and nanomaterial-based infected wound therapy. Practical antibacterial applications employing photothermal antimicrobial agents, alone or in synergistic combination with other nanomaterials, are considered. Existing challenges and limitations in photothermal antimicrobial therapy and future perspectives are presented from the structural, functional, safety, and clinical potential points of view.
  • RAPID MANUFACTURING OF FLEXIBLE MICROSTRUCTURED PDMS SUBSTRATES, USING 3D DPL PRINTING TECHNIQUE, FOR FLEXIBLE PRESSURE SENSORS

    Nanomaterials, 2022
    Annually, antimicrobial-resistant infections-related mortality worldwide accelerates due to the increased use of antibiotics during the coronavirus pandemic and the antimicrobial resistance, which grows exponentially, and disproportionately to the current rate of development of new antibiotics. Nanoparticles can be an alternative to the current therapeutic approach against multi-drug resistance microorganisms caused infections. The motivation behind this work was to find a superior antibacterial nanomaterial, which can be efficient, biocompatible, and stable in time. This study evaluated the antibacterial activity of ZnO-based nanomaterials with different morphologies, synthesized through the solvothermal method and further modified with Au nanoparticles through wet chemical reduction. The structure, crystallinity, and morphology of ZnO and ZnO/Au nanomaterials have been investigated with XRD, SEM, TEM, DLS, and FTIR spectroscopy. The antibacterial effect of unmodified ZnO and ZnO/Au nanomaterials against Escherichia coli and Staphylococcus aureus was investigated through disc diffusion and tetrazolium/formazan (TTC) assays. The results showed that the proposed nanomaterials exhibited significant antibacterial effects on the Gram-positive and Gram-negative bacteria. Furthermore, ZnO nanorods with diameters smaller than 50 nm showed better antibacterial activity than ZnO nanorods with larger dimensions. The antibacterial efficiency against Escherichia coli and Staphylococcus aureus improved considerably by adding 0.2% (w/w) Au to ZnO nanorods. The results indicated the new materials’ potential for antibacterial applications.
  • PDMS Based Microfluidics Fabrication Using 3D-Printed Molds

    Proceedings of the International Semiconductor Conference CAS, 2022
    Microfluidic devices have a central role in many biomedical applications, and there are many fabrication methods to obtain microchannels and reservoirs. Polydimethylsiloxane (PDMS) based microfluidics register an intense development due to the well-known advantages of this material. New manufacturing methods are needed as an alternative to commonly used soft lithography in order to produce inexpensive microfluidic devices. In this paper, we present a simple and reliable technique to obtain PDMS based microfluidic devices. We used digital light processing (DLP) 3D printing for rapid fabrication of resin mold for PDMS structures. UV and thermal post-treatment of printed mold led to high quality molds. Thin aluminum film deposition on resin mold provided a buffer layer to prevent PDMS curing inhibition. Glass was used as substrate material and part of the microchannels wall. Resulted microfluidic parts have a reduced roughness and can ensure robust integrity for the microchannels and chambers.

    The deleterious effects of the coronavirus disease 2019 (COVID-19) pandemic urged the development of diagnostic tools to manage the spread of disease. Currently, the “gold standard” involves the use of quantitative real-time polymerase chain reaction (qRT-PCR) for SARS-CoV-2 detection. Even though it is sensitive, specific and applicable for large batches of samples, qRT-PCR is labour-intensive, time-consuming, requires trained personnel and is not available in remote settings. This review summarizes and compares the available strategies for COVID-19: serological testing, Point-of-Care Testing, nanotechnology-based approaches and biosensors. Last but not least, we address the advantages and limitations of these methods as well as perspectives in COVID-19 diagnostics. The effort is constantly focused on understanding the quickly changing landscape of available diagnostic testing of COVID-19 at the clinical levels and introducing reliable and rapid screening point of care testing. The last approach is key to aid the clinical decision-making process for infection control, enhancing an appropriate treatment strategy and prompt isolation of asymptomatic/mild cases. As a viable alternative, Point-of-Care Testing (POCT) is typically low-cost and user-friendly, hence harbouring tremendous potential for rapid COVID-19 diagnosis.
