Special Issue Information

Dear Colleagues,

Nanostructured materials play a significant role in generating new advanced classes of products with biomedical and healthcare applications. They will undoubtedly continue to develop and improve in the future. The unique physicochemical properties of nanomaterials that substantially differ from the same type of substance with micro or macro size influence and provide new advantageous biological activities like antimicrobial, antiviral, anti-inflammatory, and anticancer effects, the ability to cross biological barriers, biocompatibility, etc. These important features highlight nanostructured materials as prominent candidates for the generation of improved scaffolds for tissue engineering, the development of drug-, gene-, and siRNA-delivery systems for the treatment and therapy of various diseases (cancer, infectious diseases, genetic, and autoimmune disorders), the production of sophisticated biosensors, wound dressings, and medical implants. In addition, the generation of nanostructured surfaces brings new opportunities to engineer multifunctional interfaces with important biomedical and clinical potential.

The purpose of this Special Issue is to consolidate recent findings and provide new insights into the production and characteristics of nanostructured materials and interfaces with biomedical significance. Thus, we aim for this Special Issue to serve as an invaluable reference to those working on the design of novel nanostructured materials and interfaces for healthcare applications.

Research topics of interest of the present Special Issue include, but are not limited to, the following:

  • Design and synthesis of nanostructured materials and interfaces, evaluations of their physicochemical properties, biological activity, and healthcare potential;
  • Recent scientific and technological developments of nanostructured materials and interfaces and emerging biomedical and clinical applications;
  • Surface characterization and current challenges in processing technologies and engineering specific interfaces relevant for biomedical use;
  • Different methods and alternative technologies to obtain multifunctional 2D and 3D nanostructured interfaces with biomedical and healthcare applications.

We look forward to receiving your contributions.

The purpose of this research was to analyze the antiviral activity of coatings based on ZnO nanoparticles and TiO2. The goal was also to investigate the influence of accelerated UV-B and Q-SUN irradiation on their effectiveness. The results of the performed analysis demonstrated that only one of four coatings containing nanoparticles demonstrated high antiviral activity. Q-SUN irradiation had a positive influence on the antiviral properties of the other three coatings. After 24 h of accelerated irradiation, these coatings demonstrated moderate antiviral effectiveness, confirming that Q-SUN irradiation improved the properties of the active layers (by activating ZnO nanoparticles and TiO2). Unfortunately, after 48 h of irradiation, the activity of the coatings decreased, confirming that the irradiation time should not be too long. Comparing the influence of the UV-B irradiation on the coating activity to the Q-SUN irradiation, it has to be mentioned that UV-B irradiation (24 h) also improved the antiviral properties of the three coatings, which were not active before irradiation. However, it decreased the activity of the coating that was active before UV aging. Unfortunately, none of those analyzed coatings were active after 48 h of UV-B irradiation, confirming that the irradiation time should be shorter. Full article

In this study, the hydroxyapatite (HAp) in the form of nanoparticles was synthesized through the wet co-precipitation method and loaded with plant extract from Calendula officinalis L. rich in biologically active myo-inositol, and the 5-fluorouracil anticancer drug. The obtained nanomaterials have rod-like structures approx. 30 nm in diameter and 100 nm in length. FT-IR analysis results proved the immobilization of biologically active compounds. The loading of plant extract into the carrier improved the stability of colloidal suspension, which was confirmed with turbidimetry. The composite modified with calendula extract and drug (HAp@Cal@5-flu) effectively scavenges the DPPH radicals, with a radical scavenging activity (RSA) of about 20.0 ± 1.3%. The effect is supported by the DFT calculations of the HOMO-LUMO, presenting the chemical reactivity of the molecules loaded into the HAp. The in vitro cytotoxicity results on SKOV-3 ovarian cancer cells show the pronounced cytotoxic effect of the HAp@Cal@5-flu. The calendula extract loading into the carrier provided better interactions with the tumorous biomimetic membranes studied with a Langmuir trough, making it a promising material in nano-biomedicine, including drug delivery and targeted cancer treatment.

Photocatalytic technologies represent an innovative method to reduce microbial load on surfaces, even considering recent public health emergencies involving coronaviruses and other microorganisms, whose presence has been detected on surfaces. In this review paper, the antimicrobial efficacy of various photocatalysts applied by different coating methods on different surfaces has been compared and critically discussed. Publications reviewing the use of photocatalytic coatings on surfaces for antimicrobial effectiveness have been examined. Clear search parameters were employed to analyze the PubMed, Scopus, and WOS databases, resulting in 45 papers published between 2006 to 2023 that met the inclusion criteria. The paper assessed various types of photocatalytic coatings that targeted different microbial objectives. Based on the pooled data analysis, the TiO2 coating exhibited a substantial effect in decreasing bacteria strains, both Gram-positive and -negative (99.4%). Although the diversity of these technologies poses significant obstacles to obtaining a comprehensive final assessment of their effectiveness and feasibility for surface application, subgroup analysis indicated significant variations in the removal efficiency of Gram-positive strains based on different surface types (p = 0.005) and time of exposure (p = 0.05). Photocatalytic coatings provide a promising approach to combating the spread of microorganisms on surfaces. Further “in-field” investigations are necessary in the foreseeable future to explore and optimize this novel and exciting health technology. Full article
