“…A few research teams have investigated the possibility of developing smart plasmonic hydrogels for biomedical applications focusing their scientific activities on the use of different kind of polymer matrices, including chitosan‐based hydrogels, [ 81 ] polyvinyl alcohol (PVA), [ 82 ] DNA hydrogel, [ 83 ] and poly‐(ethylene glycol) diacrylate (PEGDA). [ 84 ] Although a broad range of hydrogels could be applied in this field incorporating AuNPs in their polymer networks, thermoresponsive polymers (e.g., PNIPAM) stand out from the crowd since, in this case, light could trigger a cascade‐like series of responses and new functionalities.…”

Thermoplasmonics deals with the generation and manipulation of nanoscale heating associated with noble metallic nanoparticles. To this end, gold nanoparticles (AuNPs) are unique nanomaterials with the intrinsic capability to generate a nanoscale confined light‐triggered thermal effect. This phenomenon is produced under the excitation of a suitable light of a wavelength that matches the localized surface plasmonic resonance frequency of AuNPs. Liquid crystals (LCs) and hydrogels are temperature‐sensitive materials that can detect the host AuNPs and their photo‐induced temperature variations. In this perspective, new insight into thermoplasmonics, by describing a series of methodologies for monitoring, detecting, and exploiting the photothermal properties of AuNPs, is offered. From conventional infrared thermography to highly sophisticated temperature‐sensitive materials such as LCs and hydrogels, a new scenario in thermoplasmonic‐based, next generation, photonic components is presented and discussed. Moreover, a new road in thermoplasmonic‐driven biomedical applications, by describing compelling and innovative health technologies such as on‐demand drug‐release and smart face masks with smart nano‐assisted destruction of pathogens, is proposed. The latter represents a new weapon in the fight against COVID‐19.

The sensitivity and reproducibility of the lateral flow assay can be influenced by multiple factors, such as the size of gold nanoparticles (GNPs) employed. Here, we evaluated the analytical performance of single-sized and mixed-sized GNPs using a simple lateral flow assay (LFA) platform. This platform was used as a model assay to diagnose albumin levels and demonstrate the analytical performance of single-sized and mixed-sized GNPs in LFA tests. Two sizes of GNPs@anti-bovine serum albumin (BSA) conjugate proteins were mixed at different ratios. The unique optical properties of the GNPs induced a distinguishing color-shedding effect on the single- and mixed-sized GNPs@anti-BSA conjugates interacting with the target analyte BSA spotted on the test line. The use of mixed-sized GNPs@anti-BSA conjugates enhanced signal relative to the 20 nm GNPs, and provided superior stability compared with solely employing the large GNPs (50 nm). The proposed platform in this study could provide an efficient BSA detection mechanism that can be utilized as a model biomarker for confronting chronic kidney disease.

The applications of functional polymers to different research fields have been increasing. An especially important application is the use of polymer‐based sensors for the chromogenic detection of compounds of environmental interest in water. Polymer matrix supports have been developed to improve the sensing capacity and performance of chromogenic sensors. Therefore, research in the area of sensor design and manufacturing for pollutant detection is increasingly interesting to many scientific communities ranging from biological and chemical sciences to engineering. This subject of this review is colorimetric sensors that enable the rapid and quantitative detection of different analytes within a laboratory setup. The applications of different types of polymer‐based sensors used in the chromogenic detection of compounds of environmental interest are reviewed and analysed. © 2021 Society of Industrial Chemistry.
