Abstract
Anti-virulence therapy that interferes with bacterial communication, known as "quorum sensing (QS)", is a promising strategy for circumventing bacterial resistance. Using nanomaterials to regulate bacterial QS in anti-virulence therapy has attracted much attention, which is mainly attributed to unique physicochemical properties and excellent designability of nanomaterials. However, bacterial QS is a dynamic and multistep process, and there are significant differences in the specific regulatory mechanisms and related influencing factors of nanomaterials in different steps of the QS process. An in-depth understanding of the specific regulatory mechanisms and related influencing factors of nanomaterials in each step can significantly optimize QS regulatory activity and enhance the development of novel nanomaterials with better comprehensive performance. Therefore, this review focuses on the mechanisms by which nanomaterials regulate bacterial QS in the signal supply (including signal synthesis, secretion, and accumulation) and signal transduction cascade (including signal perception and response) processes. Moreover, based on the two key influencing factors (i.e., the nanomaterial itself and the environment), optimization strategies to enhance the QS regulatory activity are comprehensively summarized. Collectively, applying nanomaterials to regulate bacterial QS is a promising strategy for anti-virulence therapy. This review provides reference and inspiration for further research on the anti-virulence application of nanomaterials.

MATERIALS SCIENCE & ENGINEERING. C, MATERIALS FOR BIOLOGICAL APPLICATIONS 2019; 109:110617. [PMID: 32229008 DOI: 10.1016/j.msec.2019.110617] [Citation(s) in RCA: 32] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/12/2019] [Revised: 09/23/2019] [Accepted: 12/28/2019] [Indexed: 12/24/2022]
Abstract
The present study was performed to synthesize, for the first time, the magnesium oxide nanoparticles (MgO NPs) using the cell filtrate of the endobacterium Burkholderia rinojensis. The MgO NPs were characterized by Ultraviolet-visible (UV-Vis), Fourier-transform infrared (FTIR), X-ray diffraction (XRD), Energy dispersive X-ray (EDX), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and zeta potential (ZP). The UV spectrum of the MgO NPs showed a sharp absorption peak at 330 nm. The FTIR results confirm that the bioactive compounds act as reducing and capping agents of synthesized MgO NPs. The XRD pattern showed three major peaks of the crystalline metallic MgO NPs. Presence of magnesium and oxygen were confirmed by EDX profile. Both SEM and TEM revealed the MgO NPs as roughly spherical granular structures, and the size was 26.70 nm. The zeta potential was -32.1 mV, which indicated the stability of the MgO NPs in suspension. The MgO NPs showed considerable antifungal and antibiofilm activities against Fusarium oxysporum f. sp. lycopersici. At the concentration of 15.36 μg/ml, the MgO NPs completely inhibited the mycelial growth of the fungus. The biofilm formation of the pathogen was completely suppressed by MgO NPs at 1.92 μg/ml. The MgO NPs caused severe morphological changes on the hyphal morphology and biofilm formation of the fungus with significant damage on the fungal membrane integrity.

Abstract
The toxicity of engineered nanoparticles (ENPs) on bacteria has aroused much interest. However, few studies have focused on the effects of low-level ENPs on bacterial group behaviors that are regulated by quorum sensing (QS). Herein, we investigated the effects of nine ENPs (Ag, Fe, ZnO, TiO2, SiO2, Fe2O3, single-wall carbon nanotubes (SWCNTs), graphene oxide (GO), and C60) on QS in Pseudomonas aeruginosa PAOl. An ENP concentration of 100 μg L-1 did not impair bacterial growth. However, concentrations of 100 μg L-1 of Ag and GO ENPs induced significant increases in 3OC12-HSL in the culture and significantly promoted protease production and biofilm formation of PAO1. C4-HSL synthase and its transcription factors were less sensitive to 100 μg L-1 Ag and GO ENPs compared with 3OC12-HSL. Fe ENPs induced a significant increase in the 3OC12-HSL concentration, similar to Ag and GO ENPs. However, Fe ENPs did not induce any significant increase in protease production or biofilm formation. Different size distributions, chemical compositions, and aggregation states of the ENPs had different effects on bacterial QS. These whole circuit indicators could clarify the effects of ENPs on bacterial QS. This study furthers our understanding of the effects of low-level ENPs on bacterial social behaviors.

Abstract
Despite several conventional potent antibacterial therapies, bacterial infections pose a significant threat to human health because they are emerging as the leading cause of death worldwide. Due to the development of antibiotic resistance in bacteria, there is a pressing demand to discover novel approaches for developing more effective therapies to treat multidrug-resistant bacterial strains and biofilm-associated infections. Therefore, attention has been especially devoted to a new and emerging branch of science "nanotechnology" to design non-conventional antimicrobial chemotherapies. A range of nanomaterials and nano-sized carriers for conventional antimicrobial agents have fully justified their potential to combat bacterial diseases by reducing cell viability, by attenuating quorum sensing, and by inhibiting/or eradicating biofilms. This communication summarizes emerging nano-antimicrobial therapies in treating bacterial infections, particularly using antibacterial, quorum quenching, and anti-biofilm nanomaterials as new approaches to tackle the current challenges in combating infectious diseases.

Abstract
Semiconductor sensitized solar cells, a promising candidate for next-generation photovoltaics, have seen notable progress using 0-D quantum dots as light harvesting materials. Integration of higher-dimensional nanostructures and their multi-composition variants into sensitized solar cells is, however, still not fully investigated despite their unique features potentially beneficial for improving performance. Herein, CdSe/CdSexTe1−x type-II heterojunction nanorods are utilized as novel light harvesters for sensitized solar cells for the first time. The CdSe/CdSexTe1−x heterojunction-nanorod sensitized solar cell exhibits ~33% improvement in the power conversion efficiency compared to its single-component counterpart, resulting from superior optoelectronic properties of the type-II heterostructure and 1-octanethiol ligands aiding facile electron extraction at the heterojunction nanorod-TiO2 interface. Additional ~32% enhancement in power conversion efficiency is achieved by introducing percolation channels of large pores in the mesoporous TiO2 electrode, which allow 1-D sensitizers to infiltrate the entire depth of electrode. These strategies combined together lead to 3.02% power conversion efficiency, which is one of the highest values among sensitized solar cells utilizing 1-D nanostructures as sensitizer materials.
