Sericin-Based Bio-Inspired Nano-Engineering of Heterometallic AgAu Nanocubes for Attomolar Mefenamic Acid Sensing in the Mobile Phone-Based Surface Plasmon-Coupled Interface

“…Subsequently, synthesized NP and nanohybrid characterization was performed using UV–vis–NIR, DLS, and SEM instrumentation. This process is termed “frugal” on account of its simplicity wherein NPs and hybrids are formed without any additional requirements of reducing and capping agents as well as altered temperatures or pressures. ,, These materials were further evaluated in the SPCE platform for their performance as fluorescence enhancers.…”

“…The property of the evanescent wave generated in the surface plasmon-coupled emission (SPCE) platform has been effectively modulated with different nano-engineering strategies in the past decade. Nanomaterials sustaining metal plasmons (Ag, Au, Pt), , dielectric plasmons (Nd 2 O 3 , TiC, TiN, TiCN), − magnetic plasmons, and graphene Dirac fermions and other 2D material plasmons − have been evaluated in the SPCE platform to comprehend insightful attributes of light–matter interactions such as Rabi splitting, Fabry–Perot photonic mode coupling, Casimir force, Fano resonance, quantum confinement, and Purcell effect. ,, Consequently, the aforementioned strategies aim at augmenting electromagnetic (EM) field intensity at the nanogaps between plasmonic nanomaterials and the metal thin film, which are termed as “hotspots” that are essentially utilized for demonstrating novel biosensing frameworks.…”

“…Recently, such hotspots generated with different nano-architectures (shape, size, and ensembles/precise assemblies) presenting unique properties have been evaluated in the SPCE platform toward a variety of applications in the broad arena of photo-plasmonics. , This includes transformative technologies such as fluorescent polymer brushes and their growth, picomolar sensing of coronary heart disease biomarker lipoprotein-associated phospholipase A2 (LpPLA2), universal biochip sensors with a functional “molecular beacon”, monomer–higher aggregate energy transition, geometry switching of analytes, polymer light-emitting diodes, and multiplexing-based biosensors, to name a few. Notably, from extensive background research, it is observed that there are a few original studies that examine the prominence of bio-inspired nanohybrids synthesized via go-green approaches for generation of hotspots in the SPCE platform. , Moreover, very limited evidence is available on the systematic study of utilizing largely available sericin protein as a bio-inspired source for the synthesis of plasmonic nanohybrids. Conventionally, exorbitant, toxic, and corrosive capping and reducing agents (such as citrate, hydrazine, and sodium borohydride) are being employed for generating structurally and optically tunable nanomaterials, which in turn results in detrimental effects on the terrestrial and aquatic life systems. ,, In this regard, awareness toward green nanochemistry principles is growing rapidly in the physics, chemistry, and materials science as well as biosciences research community. − In light of these observations, in the current work, we developed a rapid, low-cost, frugal nano-engineering technique for the synthesis of plasmonic Ag, Au, and AgAu nanohybrids via a green approach.…”

While conventional nano-engineering techniques suffer from the abovementioned caveats, here, we demonstrate a user-eco-friendly, non-hazardous sericin protein as both a capping and reducing agent for synthesis of nanomaterials upon ultraviolet (UV) irradiation.…”

The Using of Nanoparticles of Microalgae in Remediation of Toxic Dye from Industrial Wastewater: Kinetic and Isotherm Studies

“…Synthetic dyes are polluting chemicals that have both harmful and aesthetic effects on aquatic habitats. Dye effluents, which contain dyed organic molecules, increase the organic load in water bodies and reduce sunlight penetration, reducing phytoplankton photosynthetic activity and altering the biological balance of the aquatic ecosystem [ 1 ]. Dyes are significant dangerous materials used in several industrial sectors.…”
