“…Using nanomaterials has great advantages in applications targeting DNA, RNA, proteins, and other small ligands/molecules [ 20 ]. LSPR biosensors with AuNPs have the advantage of being able to detect small analytes and have been successfully applied in clinical diagnostics [ 21 ]. A shift in the absorption peak when the receptor bound to the target was measured with UV‒Vis spectra [ 22 ].…”

Antibody sensor to detect viruses has been widely used but has problems such as the difficulty of right direction control of the receptor site on solid substrate, and long time and high cost for design and production of antibodies to new emerging viruses. The virus detection sensor with a recombinant protein embedded liposome (R/Li) was newly developed to solve the above problems, in which R/Li was assembled on AuNPs (Au@R/Li) to increase the sensitivity using localized surface plasmon resonance (LSPR) method. Recombinant angiotensin-converting enzyme-2 (ACE2) was used as host receptors of SARS-CoV and SARS-CoV-2, and the direction of enzyme active site for virus attachment could be controlled by the integration with liposome. The recombinant protein embedded liposomes were assembled on AuNPs, and LSPR method was used for detection. With the sensor platform S1 protein of both viruses was detected with detection limit of 10 pg/ml and SARS-CoV-2 in clinical samples was detected with 10 ~ 35 Ct values. In the selectivity test, MERS-CoV did not show a signal due to no binding with Au@R/Li. The proposed sensor platform can be used as promising detection method with high sensitivity and selectivity for the early and simple diagnosis of new emerging viruses. Graphical Abstract

“…[23,24] Due to the small number of components and their mostly small size, portable devices are also feasible. [25] Another advantage of LSPR sensor technology compared to SPR investigations is the shorter decay length of LSPR, which leads to a significantly lower background signal of the medium. [26] At the same time, the LSPR is less sensitive to temperature, which also makes the measurements easier.…”

The development of rapid, simple, and accurate bioassays for the detection of nucleic acids has received increasing demand in recent years. Here, localized surface plasmon resonance (LSPR) spectroscopy for the detection of an antimicrobial resistance gene, sulfhydryl variable β‐lactamase (blaSHV), which confers resistance against a broad spectrum of β‐lactam antibiotics is used. By performing limit of detection experiments, a 23 nucleotide (nt) long deoxyribonucleic acid (DNA) sequence down to 25 nm was detected, whereby the signal intensity is inversely correlated with sequence length (23, 43, 63, and 100 nt). In addition to endpoint measurements of hybridization events, the setup also allowed to monitor the hybridization events in real‐time, and consequently enabled to extract kinetic parameters of the studied binding reaction. Performing LSPR measurements using single nucleotide polymorphism (SNP) variants of blaSHV revealed that these sequences can be distinguished from the fully complementary sequence. The possibility to distinguish such sequences is of utmost importance in clinical environments, as it allows to identify mutations essential for enzyme function and thus, is crucial for the correct treatment with antibiotics. Taken together, this system provides a robust, label‐free, and cost‐efficient analytical tool for the detection of nucleic acids and will enable the surveillance of antimicrobial resistance determinants.

“…Among them, plasmons are widely used in solar photothermal conversion. When the incident photon frequency matches the overall vibrational frequency of the metal nanoparticle conduction electrons, an extremely resonance peak is generated in the absorption spectrum of the metal nanoparticle, [ 19 ] followed by the local thermalization around the nanoparticles. For example, metal nanoparticles based on carbon‐based materials can reach high temperatures much above the boiling point of water, which facilitates the evaporation of surrounding water.…”

Fresh water resources can be sustainably harvested through interfacial evaporation by solar energy. To enhance the efficiency of solar interfacial evaporation, a metal graphene alcohol gel was synthesized using a one‐step thermal reduction technique. Subsequently, a metal graphene aerogel was produced using freeze‐drying technology. The hydrothermal treatment method was applied to introduce asymmetric moisture and roughness on the upper and lower surfaces of the aerogel. The unique structure of the aerogel plays a significant role in facilitating continuous water transport to the interface for evaporation. The top layer, being hydrophobic, and the bottom layer, being hydrophilic, contribute to this process. Importantly, the top layer’s design ensures that an excessively thick water film does not form, thereby preventing any adverse effects on light absorption efficiency. The aerogel exhibits an outstanding water evaporation rate (WER) is 1.75 kg·m‐2·h‐1 and a remarkable photothermal conversion efficiency (PTCE) is 93.17% under one solar radiation intensity. This is because the aerogel has a unique three‐dimensional structure. This special three‐dimensional structure has an interconnected microporous‐like appearance inside, which increases the evaporation area. Metal‐graphene aerogel is based on the electric field dielectric evaporation mechanism of metal nanoparticles localized surface plasmon resonance (LSPR) effect and the thermal mediated evaporation mechanism of graphene full spectrum. Under the double action, the photothermal conversion efficiency has been significantly improved. Our meticulously created metallic graphene aerogel performs exceptionally well at evaporating water. As a result, it presents a promising and practical avenue for exploring effective solar interfacial evaporation.This article is protected by copyright. All rights reserved.
