“…20 In nanocomposites, it has been shown that the interface between the two components, that is, the NP and the matrix, is critical and strongly affects the properties of the material. 21 Incorporating NPs into a polymer matrix, for example, a block copolymer, impacts a wide range of material properties, such as mechanical strength, conductivity, permeability, catalytic activity, and optical and magnetic properties. 22,23 Here, we use the NAIM approach to carefully study the NP−matrix interaction through the recognition effect.…”

Nanoparticle-imprinted matrices (NAIMs) are an innovative approach for the efficient and selective recognition of nanoparticles (NPs). The NAIM system comprises the preparation of thin films in which NPs are embedded as a template. The removal of the template forms nanometric voids, which are subsequently used for the selective reuptake of NPs identical to those imprinted. The recognition ability depends on several parameters such as the geometrical compatibility between the voids and imprinted NPs, the thickness of the matrix, and the supramolecular interactions between the matrix and the NP capping agents. Herein, we studied carefully the NP−matrix interactions in three NAIM systems, which were prepared by imprinting identical-sized AuNPs, bearing different carboxylic acidfunctionalized thiols as capping agents, in a carboxylic acid-functionalized matrix. This experimental setup has enabled us to meticulously examine the selectivity of the NAIM systems driven by matrix−shell interactions. The three studied NAIM systems have shown high and selective reuptake ability once exposed to solutions of NPs stabilized with the same capping agent used for the imprinting process. In particular, the reuptake percentage of the originally imprinted AuNPs ranges from 50 to 80%, whereas the reuptake of AuNPs bearing different carboxylic capping agents than those imprinted was substantially lower (1−11%). Surfacesensitive polarization-modulation infrared reflection-absorption spectroscopy was utilized to correlate the selectivity of the NAIM systems and hydrogen bonding detected between the capping agents and the matrix. This study paves the way for the rational design of NAIM systems, which can be tuned according to the desired shell−matrix interactions and eventually applied in sensing and separation technologies.

“…Surface modification of nanoparticles and self-assembled monolayers (SAMs) [89] are techniques that were established to bond the fillers to the resin to advance the connections between the filler particles and the adjoining polymer [89,90]. Yet, these methods progress the efficacy of transferring stress at the interface.…”

Low-Shrinkage Resin Matrices in Restorative Dentistry-Narrative Review

et al. 2022

Dimethacrylate-based resin composites restorations have become widely-used intraoral materials in daily dental practice. The increasing use of composites has greatly enhanced modern preventive and conservative dentistry. They have many superior features, especially esthetic properties, bondability, and elimination of mercury and galvanic currents. However, polymeric materials are highly susceptible to polymerization shrinkage and stresses that lead to microleakage, biofilm formation, secondary caries, and restoration loss. Several techniques have been investigated to minimize the side effects of these shrinkage stresses. The primary approach is through fabrications and modification of the resin matrices. Therefore, this review article focuses on the methods for testing the shrinkage, as well as formulations of resinous matrices available to reduce polymerization shrinkage and its associated stress. Furthermore, this article reviews recent cutting-edge developments on bioactive low-shrinkage-stress nanocomposites to effectively inhibit the growth and activities of cariogenic pathogens and enhance the remineralization process.

Magnetic [FA‐c‐(C‐DTX)@Fe3O4] nanocomposites have been prepared with a four‐step technique involving three mechanical stirring conventional steps to obtain [(FA‐c‐(DTX‐g‐DAC)] and an ultrasound‐assisted Fe3O4 coating approach to fabricate [FA‐c‐(C‐DTX)@Fe3O4]. Magnetic nanoparticles (NPs) (Fe3O4 NPs) synthesis and integration has been easily and rapidly approached under novel environmentally friendly optimized reaction conditions: an ethanol–water solution, one iron precursor use, short reaction time, low temperature, and an ultrasonic irradiation process. This new condition's unique combination is attributed to our new synthesis procedure. Sonochemically synthetisized [FA‐c‐(C‐DTX)@Fe3O4] were easily separated from the reaction mixture simply via external magnetic field application, and therefore, neither filtration nor centrifigation was required. The synthetisized samples have been investigated by Fourier transform infrared (FTIR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, X‐ray photoelectron spectroscopy (XPS), X‐ray diffraction (XRD), thermogravimetry analysis (TGA), scanning electron microscopy (SEM), and vibrating‐sample magnetometry (VSM). Obtained outcomes including successful magnetite coating process, good crystallinity, homogenous morphology, enhanced thermal stability, and obvious magnetic properties suggested the potential of sonochemical procedure to fabricate and integrate magnetic NPs. This sonochemically synthesized catalyst was evaluated toward the reduction of the organic pollutant 4‐nitrophenol and showed excellent catalytic activity. This ultrasound‐assisted nanocomposites preparation is simply scalable to meet industrial application.
