Material Breakthroughs in Smart Food Monitoring: Intelligent Packaging and On‐Site Testing Technologies for Spoilage and Contamination Detection

“…[28] Concurrently, particle-based form factors are also commonly employed, as they are particularly valuable within in-solution platforms, where they pair high surface area-to-volume ratios with mobility within the test sample, increasing the likelihood of probe-target interactions. [29][30][31][32] Further, their size confinement effect yields electronic and optical properties that facilitate their use as electrostatic target detectors and colorimetric transducers, respectively. [29] Namely, Au nanoparticles (AuNPs) are well noted for their ability to both quench or enhance the signal of fluorescent molecules, based on their size and specific characteristics of a given system.…”

“…[29] Namely, Au nanoparticles (AuNPs) are well noted for their ability to both quench or enhance the signal of fluorescent molecules, based on their size and specific characteristics of a given system. [30,33] Recognizing the high cost of pure metallic substrates, there has been continued emphasis on the development of hybrid platforms that employ metallic agents as a component of the sensing substrate. Namely, recent works in the food sensing have employed Au and silver (Ag) nanoparticles as substrate components within plasmonic sensors.…”

Fabrication of Silver Nanoparticles in Aqueous Solution by Laser Technique and Study of Their Hemocompatibility and Antibacterial Effects Against Dental Decay Bacteria

“…When certain materials, such as metal oxide semiconductors, are reduced to exceedingly small dimensions, they can produce entirely new materials with novel electronic and optical properties [9][10][11]. The main things that affect the shape and size of nanoscale materials that can be made by laser ablation in liquid are the strength of the la ser, the wavelength of the laser, and the length of the laser's pulse [12][13][14]. The presence of harmful bacteria within the mouth cavity causes caries, an acute disease.…”

Lattice dynamics study of gold nanotube

“…The study and control of phonon propagation and thermal conductivity of materials at nanoscale is important for their applications in areas such as energy conversion and transport, photo acoustic imaging etc [6,7]. Gold and Carbon nanowires and nanotubes are extensively researched for their applications in sensing devices, biomedicine, energy sector etc [8][9][10][11][12][13].…”
