[PMID: 38869528 PMCID: PMC11173812 DOI: 10.3390/nano14110903] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/18/2024] [Revised: 05/13/2024] [Accepted: 05/17/2024] [Indexed: 06/14/2024]
Abstract
The sol-gel chemistry of silica has long been used for manipulating the size, shape, and microstructure of mesoporous silica particles. This manipulation is performed in mild conditions through controlling the hydrolysis and condensation of silicon alkoxide. Compared to amorphous silica particles, the preparation of mesoporous silica, such as MCM-41, using the sol-gel approach offers several unique advantages in the fields of catalysis, medicament, and environment, due to its ordered mesoporous structure, high specific surface area, large pore volume, and easily functionalized surface. In this review, our primary focus is on the latest research related to the manipulation of mesoporous silica architectures using the sol-gel approach. We summarize various structures, including hollow, yolk-shell, multi-shelled hollow, Janus, nanotubular, and 2D membrane structures. Additionally, we survey sol-gel strategies involving the introduction of various functional elements onto the surface of mesoporous silica to enhance its performance. Furthermore, we outline the prospects and challenges associated with mesoporous silica featuring different structures and functions in promising applications, such as high-performance catalysis, biomedicine, wastewater treatment, and CO2 capture.

Abstract
Essential oils have become increasingly popular in fields of medical, food and agriculture, owing to their strongly antimicrobial, anti-inflammation and antioxidant effects, greatly meeting demand from consumers for healthy and safe natural products. However, the easy volatility and/or chemical instability of active ingredients of essential oils (EAIs) can result in the loss of activity before realizing their functions, which have greatly hindered the widely applications of EAIs. As an emerging trend, micro/mesoporous nanomaterials (MNs) have drawn great attention for encapsulation and controlled release of EAIs, owing to their tunable pore structural characteristics. In this review, we briefly discuss the recent advances of MNs that widely used in the controlled release of EAIs, including zeolites, metal-organic frameworks (MOFs), mesoporous silica nanomaterials (MSNs), and provide a comprehensive summary focusing on the pore engineering strategies of MNs that affect their controlled-release or triggered-release for EAIs, including tailorable pore structure properties (e.g., pore size, pore surface area, pore volume, pore geometry, and framework compositions) and surface properties (surface modification and surface functionalization). Finally, the variegated applications and potential challenges are also given for MNs based delivery strategies for EAIs in the fields of healthcare, food and agriculture. These will provide considerable instructions for the rational design of MNs for controlled release of EAIs.

Abstract
The formation of pathogenic biofilms on medical devices is a major public health concern accounting for over 65% of healthcare-associated infections and causing high infection morbidity, mortality, and a great burden to patients and the healthcare system due to its resistance to treatment. In this study, we developed a chitosan-based antimicrobial coating with embedded mesoporous silica nanoparticles (MSNs) to load and deliver eugenol, an essential oil component, to inhibit the biofilm formation of common bacteria in medical-device-related infections. The eugenol-loaded MSNs were dispersed in a chitosan solution, which was then cross-linked with glutaraldehyde and drop-casted to obtain coatings. The MSNs and coatings were characterized by dynamic light scattering, Brunauer-Emmett-Teller analysis, attenuated-total-reflectance Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, 3D optical profilometry, and scanning electron microscopy. The release behavior of eugenol-loaded MSNs and coatings and the antibiofilm and antimicrobial activity of the coatings against adherent Staphylococcus aureus, methicillin-resistant S. aureus, and Pseudomonas aeruginosa were investigated. Eugenol was released from the MSNs and coatings in aqueous conditions in a controlled manner with an initial low release, followed by a peak release, a decrease, and a plateau. While the chitosan coatings alone or with unloaded MSNs demonstrated limited antimicrobial effects and still supported biofilm formation after 24 h, the coating containing eugenol not only reduced biofilm formation but also killed the majority of the attached bacteria. It also showed biocompatibility in indirect contact with NIH/3T3 fibroblasts and a high percentage of live cells in direct contact. However, further investigations into cell proliferation in direct contact are recommended. The findings indicated that the chitosan-based coating with eugenol-loaded MSNs could be developed into an effective strategy to inhibit biofilm formation on medical devices.

Polymeric Surfactant (PIBSA-X) Facilitates the Formation of a Water-in-Oil Emulsion Reactor for the Preparation of Ultrasmall Nanosilica. ACS OMEGA 2023; 8:44647-44658. [PMID: 38046313 PMCID: PMC10688208 DOI: 10.1021/acsomega.3c05335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/23/2023] [Revised: 10/28/2023] [Accepted: 10/31/2023] [Indexed: 12/05/2023]
Abstract
Despite the widespread application of ultrasmall nanosilica, solving its aggregation problem during the preparation process remains a challenge. In this paper, ultrasmall nanosilica with a controllable size and aggregates were prepared through the water-in-oil (W/O) emulsion method by using polyisobutylene succinic anhydride-type polymeric surfactants (PIBSA-X) as an isolating agent. PIBSA-X polymeric surfactants with different hydrophilic groups were prepared using industrial-grade PIBSA, which can form stable W/O-type emulsions well. Subsequently, the W/O-type emulsion droplets were used as reactors and tetraethyl orthosilicate was hydrolyzed under ammonia alkaline conditions to synthesize ultrasmall nanosilica (10 nm). Furthermore, the morphological evolution of nanosilica aggregates can be tuned by varying the oil/water ratio, which controls the emulsion droplets. A possible mechanism is proposed to explain why the emulsion method approach affords nanosilica aggregates with various morphologies and pellet size in water-in-oil (W/O-type) emulsion droplets. This study provides a precise and simple synthetic method for the development of ultrasmall nanosilica, which has good potential to be industrialized.

Abstract
Chiral nanoparticles (NPs) with nanoscale rough surfaces have enormous application prospects in drug delivery. However, the stereoselective interactions between the chiral NPs and biosurfaces remain challenging and mysterious. Herein, we designed mesoporous silica nanocarriers (l/d/dl-TA-PEI@CMSN) exhibiting the same structural parameters (hydrophilic, electroneutral, spherical NPs, ∼120 nm) but different geometrical chirality as oral nanodrug delivery systems (Nano-DDS) for insoluble drugs nimesulide (NMS) and ibuprofen (IBU) and demonstrated their stereoselective interactions with the intestinal mucosa, that is, l-TA-PEI@CMSN as well as Nano-DDS in the l-configuration displayed apparent superior behaviors in multiple microprocesses associated with oral adsorption, including adhesion, penetration, adsorption, retention and uptake, causing by the stereomatching between the chiral mesostructures of NPs and the inherent chiral topologies of the biosurfaces. As hosting systems, l/d/dl-TA-PEI@CMSN effectively incorporated drugs in amorphous states and helped to overcome the stability, solubility and permeability bottlenecks of drugs. Subsequently, Nano-DDS in the l-configuration (including IBU/l-TA-PEI@CMSN and NMS/d-TA-PEI@CMSN owing to a chiral inversion) showed higher oral delivery efficiency of NMS and IBU evidenced by the larger relative bioavailability (1055.06% and 583.17%, respectively) and stronger anti-inflammatory and analgesic effects. In addition, l/d/dl-TA-PEI@CMSN were stable, nonirritative, biocompatible and biodegradable, benefiting for their clinical applications. These findings provided insights into the rational design of functionalized Nano-DDS and contributed to the further knowledge in the field of chiral pharmaceutical science.

Long-Term Refrigerated Storage of Beef Using an Active Edible Film Reinforced with Mesoporous Silica Nanoparticles Containing Oregano Essential Oil ( Lippia graveolens Kunth). Int J Mol Sci 2022; 24:ijms24010092.

Abstract
Beef is a fundamental part of the human diet, but it is highly susceptible to microbiological and physicochemical deterioration which decrease its shelf life. This work aimed to formulate an active edible film (AEF) incorporated with amino-functionalized mesoporous silica nanoparticles (A-MSN) loaded with Mexican oregano (Lippia graveolens Kunth) essential oil (OEO) and to evaluate its effect as a coating on fresh beef quality during refrigerated storage. The AEF was based on amaranth protein isolate (API) and chitosan (CH) (4:1, w/w), to which OEO emulsified or encapsulated in A-MSN was added. The tensile strength (36.91 ± 1.37 MPa), Young's modulus (1354.80 ± 64.6 MPa), and elongation (4.71%) parameters of AEF made it comparable with synthetic films. The antimicrobial activity of AEF against E. coli O157:H7 was improved by adding 9% (w/w) encapsulated OEO, and interactions of glycerol and A-MSN with the polymeric matrix were observed by FT-IR spectroscopy. In fresh beef, after 42 days, AEF reduced the population growth (Log CFU/cm2, relative to uncoated fresh beef) of Brochothrix thermosphacta (5.5), Escherichia coli (3.5), Pseudomonas spp. (2.8), and aerobic mesophilic bacteria (6.8). After 21 days, odor acceptability of coated fresh beef was improved, thus, enlarging the shelf life of the beef and demonstrating the preservation capacity of this film.

Abstract
Clinically, antioxidant therapy is a potential strategy for myocardial ischemia-reperfusion injury (MI/RI), a common complication of acute myocardial ischemia. The H-D-Arg-Dmt-Ly-Phe-NH2 (SS31) peptide is shown to have amazing antioxidant properties, but its utilization is limited by the peptide characteristics, such as the destruction by proteases and rapid metabolism. Silica nanoparticles (MSNs) comprise an excellent material for peptide delivery, owing to the protection effect relating to peptides. Moreover, platelet membrane (PLTM) is shown to be advantageous as a coat for nanosystems because of its specific protein composition, such that a PLTM-coated nanosystem has a stealth effect in vivo, able to target injury in the cardiovascular system. Based on this feature, we designed and prepared a novel nanocarrier to target SS31 delivery. This carrier is encapsulated by a platelet membrane and loaded with SS31 peptide into MSNs. The results reveal that this delivery system can target SS31 to the injured cardiovascular site, exert antioxidant function, and alleviate MI/RI.

Abstract
In this study, novel folate-receptor-targeted polyamidoamine (PAMAM) dendrimer functional mesoporous silica-coated magnetic nanoparticles were prepared for drug delivery agents for photodynamic therapy applications. The surface of the magnetic nanoparticles was coated with mesoporous silica (M-MSN). The M-MSN nanoparticles were functionalized with siloxane-cored PAMAM dendrons (generation 1 to 3). The surface of the M-MSN-PAMAM nanocarriers was targeted with folic acid. Indocyanine green (ICG) a near-infrared dye was loaded in the M-MSN-PAMAM nanocarriers and the photodynamic therapy efficiency of the drug-loaded nanocarriers was evaluated on MCF-7 cells. MCF-7 cells were subjected to tissue culture E-Plate that was used to generate dynamic real-time data by measuring electrical impedance across interdigitated microelectrodes on the bottom of the plate. Light source (LEDs) was designed as a system that fit 96 well-plate and cells were irradiated at 785 nm for 20 min. Also, these results were confirmed by WST-1 assay in dark and light conditions for MCF-7 cells. The results showed that in vitro application of ICG loaded M-MSN-PAMAM-FA causes apoptosis in the MCF-7 cell line.
