“…A pendulum impact testing machine (HIT5.5 P, Zwick, Ulm, Germany) with a 0.2 J pendulum tool was used ( n = 10). The Dynstat impact strength (DI, a n ) was calculated using the following equation: a n false( normalk normalJ / normalm 2 false) = W h b × 1000 where W is the impact energy (J), h is the height at the notch base (mm), and b is the width of the specimen. From the fractured fragments, the microstructural differences between the NC-PMMA specimens were observed by using FE-SEM.…”

“…Poly(methyl methacrylate) (PMMA) has been considered a ‘material of choice’ for denture base or removable prostheses due to its affordability, proper fit, ease of processing, and optimal strength and aesthetics. − However, PMMA denture base materials can easily allow for oral microorganisms to colonize the denture surface during service. In addition, not maintaining oral hygiene can accelerate the accumulation of bacteria that cause various oral and general diseases in denture wearers. − …”

Poly(methyl methacrylate) (PMMA) is commonly used for dental dentures, but it has the drawback of promoting oral health risks due to oral bacterial adhesion. Recently, various nanoparticles have been incorporated into PMMA to tackle these issues. This study aims to investigate the mechanophysical and antimicrobial adhesive properties of a denture resin by incorporating of nanoclay into PMMA. Specimens were prepared by adding 0, 1, 2, and 4 wt % surface-modified nanoclay (Sigma) to self-polymerizing PMMA denture resin. These specimens were then evaluated using FTIR, TGA/DTG, and FE-SEM with EDS. Various mechanical and surface physical properties, including nanoindentation, were measured and compared with those of pure PMMA. Antiadhesion experiments were conducted by applying a Candida albicans (ATCC 11006) suspension to the surface of the specimens. The antiadhesion activity of C. albicans was confirmed through a yeast-wall component (mannan) and mRNA-seq analysis. The bulk mechanical properties of nanoclay-PMMA composites were decreased compared to those of pure PMMA, while the flexural strength and modulus met the ISO 20795−1 requirement. However, there were no significant differences in the nanoindentation hardness and elastic modulus. The surface energy revealed a significant decrease at 4 wt % nanoclay-PMMA. The antiadhesion effect of Candida albicans was evident along with nanoclay content in the nanocomposites and confirmed by the reduced attachment of mannan on nanoclay-PMMA composites. mRNA-seq analysis supported overall transcriptome changes in altering attachment and metabolism behaviors on the surface. The nanoclay-PMMA materials showed a lower surface energy as the content increased, leading to an antiadhesion effect against Candida albicans. These findings indicate that incorporating nanoclay into PMMA surfaces could be a valuable strategy for preventing the fungal biofilm formation of denture base materials.

“…In another strategy, Algethami et al [56] created CeO 2 −SnO 2 nanofibers of 170 nm via the electrospinning method using a polyacrylonitrile polymer. The composite exhibited higher specific capacitance and improved photoelectrochemical performance, which may be attributed to the synergism between CeO 2 and SnO 2 particles in the nanofibers.…”

Present worldwide difficulties in healthcare and the environment have motivated the investigation and research of novel materials in an effort to find novel techniques to address the current challenges and requirements. In particular, the use of nanomaterials has demonstrated a significant promise in the fight against bacterial infections and the problem of antibiotic resistance. Metal nanoparticles and carbon-based nanomaterials in particular have been highlighted for their exceptional abilities to inhibit many types of bacteria and pathogens. In order for these materials to be as effective as possible, synthetic techniques are crucial. Therefore, in this review article, we highlight some recent developments in the design and synthesis of various nanomaterials, including metal nanoparticles (e.g., Ag, Zn, or Cu), metal hybrid nanomaterials, and the synthesis of multi-metallic hybrid nanostructured materials. Following that, examples of these materials’ applications in antimicrobial performance targeted at eradicating multi-drug resistant bacteria, material protection such as microbiologically influenced corrosion (MIC), or additives in construction materials have been described.

“…23 ZnO/WF had hydrophilic properties, and ZnO on the surface improved its ability to break emulsions, enhancing emulsion separation. Due to the photocatalytic and antibacterial capabilities of ZnO, 24,25 the dyes adsorbed by ZnO/WF could be self-cleaned, making recycling and long-term storage easy. The ZnO/WF composite boasted a cost-effective nature and exhibited environmental friendliness.…”
