Nam KS, Piri A, Choi S, Jung J, Hwang J. Air sampling and simultaneous detection of airborne influenza virus via gold nanorod-based plasmonic PCR. JOURNAL OF HAZARDOUS MATERIALS 2024; 477:135180. [PMID: 39067289 DOI: 10.1016/j.jhazmat.2024.135180] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/02/2024] [Revised: 07/02/2024] [Accepted: 07/09/2024] [Indexed: 07/30/2024]
Abstract
Reliable and sensitive virus detection is essential to prevent airborne virus transmission. The polymerase chain reaction (PCR) is one of the most compelling and effective diagnostic techniques for detecting airborne pathogens. However, most PCR diagnostics rely on thermocycling, which involves a time-consuming Peltier block heating methodology. Plasmonic PCR is based on light-driven photothermal heating of plasmonic nanostructures to address the key drawbacks of traditional PCR. This study introduces a methodology for plasmonic PCR detection of air-sampled influenza virus (H1N1). An electrostatic air sampler was used to collect the aerosolized virus in a carrier liquid for 10 min. Simultaneously, the viruses collected in the liquid were transferred to a tube containing gold (Au) nanorods (aspect ratio = 3.6). H1N1 viruses were detected in 12 min, which is the total time required for reverse transcription, fast thermocycling via plasmonic heating through gold nanorods, and in situ fluorescence detection. This methodology showed a limit of detection of three RNA copies/μL liquid for H1N1 influenza virus, which is comparable to that of commercially available PCR devices. This methodology can be used for the rapid and precise identification of pathogens on-site, while significantly reducing the time required for monitoring airborne viruses.

Abstract
Antisense oligonucleotide (ASO)-mediated gene silencing has broad applications, spanning from biomedicine to agriculture, involving molecular biology, synthetic biology, and genetic manipulation. This research harnessed nanotechnology to augment ASO-mediated gene silencing, introducing a remotely switchable gene expression system for precise temporal control. We targeted lipid biosynthesis and accumulation enhancement in the photosynthetic eukaryote Chlamydomonas reinhardtii. Gold nanoparticles (AuNPs) transported double-stranded DNA (dsDNA), forming dsDNA-AuNP complexes. These complexes comprised 3'-thiolated sense strands attached to AuNPs and fluorescent antisense oligonucleotides. To avoid harmful laser effects on cells, we adopted a light-emitting diode (LED). Confocal microscopy confirmed dsDNA-AuNP internalization in C. reinhardtii. LED-triggered antisense release led to an 83% decrease in Citrate Synthase 2 (CIS 2) expression. Thiolated sense strand attachment postillumination inhibited antisense reannealing, enhancing gene silencing. This led to significant lipid body accumulation in cells, verified through fluorometric and fluorescence microscopy. This union of nanotechnology and ASO-mediated silencing provides gene regulation opportunities across sectors like biomedicine and agriculture. The system's remote switching capability underscores its potential in synthetic biology and genetic engineering. Our findings substantiate the utility of this approach for enhancing lipid biosynthesis in C. reinhardtii but also underscores its broader applicability to other organisms, fostering the development of novel solutions for pressing global challenges in energy, agriculture, and healthcare.

Abstract
Research development in the precise control of gene expression in plant cells is an emerging necessity that would lead to the elucidation of gene function in these biological systems. Conventional gene-interfering techniques, such as micro-RNA and short interfering RNA, have limitations in their ability to downregulate gene expression in plants within short time periods. However, nanotechnology provides a promising new avenue with new tools to overcome these challenges. Here, we show that functionalized gold nanoparticles, decorated with sense and antisense oligonucleotides (FANSAO), can serve as a remote-control optical switch for gene interference in photosynthetic plant cells. We demonstrate the potential of employing LEDs as optimal light sources to photothermally dehybridize the oligonucleotides on the surface of metallic nanostructures, consequently inducing regulation of gene expression in plant cells. We show the efficiency of metallic nanoparticles in absorbing light from an LED source and converting it to thermal energy, resulting in a local temperature increase on the surface of the gold nanoparticles. The antisense oligonucleotides are then released due to the opto-thermal heating of the nanobiosystem composed of the metallic nanoparticles and the sense-antisense oligonucleotides. By applying this approach, we silenced the Carnitine Acyl Carnitine Translocase genes at 90.7%, resulting in the accumulation of lipid bodies in microalgae cells. These results exhibit the feasibility of using functionalized gold nanoparticles with sense and antisense oligonucleotides to enhance nucleic acid delivery efficiency and, most importantly, allow for temporal control of gene silencing in plant cells. These nanobiosystems have broad applications in the development and biosynthesis of biofuels, pharmaceuticals, and specialized chemicals.

Abstract
Hazardous ions, like those of heavy metals, cause significant health and environmental problems when they are discharged into water resources naturally or through various industrial processes. Removing these ions from water is of significant importance in the provision of high-quality water for drinking and agricultural usage. This work discusses current techniques that are frequently used for the removal of heavy-metal ions from aqueous solutions by absorption, particularly the use of biodegradable surfactants in ion flotation. Certain new surfactants promise high efficiency in their use in the ion-flotation process and in their application in industrial-water treatment to remove heavy metals. As an example, this work demonstrates the high efficiency of surfactants based on an amino-acid (L-cysteine) in removing a range of heavy-metal ions in a simple, single-stage ion-flotation process. High foaming ability, the ability to operate in various temperatures and pHs, decomposing into natural products and high binding affinity for heavy-metal ions make the cysteine-based surfactants a highly suitable compound to replace current commercial surfactants in ion- and froth-flotation processes. Removal of particular ions can also be achieved in ion flotation; a suitable choice of parameters, such as pH and surfactant concentration, favours the surfactant binding to those ions. Further intensive work is required to develop an optimal process to recover valuable elements from waste solutions.

Abstract
While research suggests that COVID-19 vaccines are effective in producing anti-SARS-CoV-2 antibodies that reduce the risk of COVID-19 and its potentially severe complications, how long these antibodies persist after the infection/vaccination is unknown. Longitudinal studies and rapid and scalable platforms are needed for large-scale sero-diagnosis and vaccine evaluation. In this study, we examine the efficacy of our recently-developed handheld thermo-photonic device for rapid and low-cost assessment of the adaptive immune response of COVID+ and COVID− patients admitted to the intensive care unit (ICU) at a local hospital due to respiratory deterioration. Antibody testing included detection and quantification of IgG and IgM via thermo-photonic sensing of a commercially available COVID-19 IgG/IgM rapid test as well as standard measurements with quantitative enzyme-linked immunosorbent assays (qELISA). The results demonstrate that the thermo-photonic reader in conjunction with COVID-19 IgG/IgM test cassettes can detect and quantify IgG levels in COVID-19 antibody assays within the clinically relevant range and with a high correlation to those obtained from qELISA. We also found that the IgG antibody is more reliable for detecting individuals with an adaptive immune response to SARS-CoV-2 compared to the IgM antibody. The developed reader offers a low-cost, portable, and scalable solution for accessing the antibody titer of individuals against SARS-CoV-2 and can be used in local hospital settings.

Abstract
Abastract
Plasmonic nanomaterials, especially a wide variety of gold nanoparticles, demonstrate great potential for theranostics of cancer. Herein, a gold nanotriangle with CD133 and hyaluronic acid on its surface loaded with a near-infrared photosensitizer was prepared for enhanced photodynamic/photothermal combined anti-tumor therapy. CD133 and hyaluronic acid provide the nanoprobe with dual tumor targeting, while the hyaluronic acid also protects photosensitive drugs from photodegradation. Thus, the nanoprobe has enhanced photothermal/photodynamic effects. This integrated treatment strategy significantly enhanced photodynamic/photothermal destruction of osteosarcoma cells. In addition, this treatment, induced by mild irradiation with a single wavelength laser, inhibited tumor growth in an osteosarcoma mouse model. These results indicate that this systemic treatment strategy can achieve enhanced anti-tumor therapeutic effects through active tumor targeting and protection of the loaded drugs.
