“…Noble metal-based nanomaterials reveal surface plasmon resonance (SPR) properties at visible wavelengths, which may cause the falsification of absorption peaks. The properties of SPR are usually influenced by the size, shape, and surface configuration of nanoantioxidants [279]. Interference of antioxidant determination assays is significantly related to the types of nanomaterials employed and their catalytic, absorption, fluorescence, and optical properties.…”

Free radicals are generated as byproducts of normal metabolic processes as well as due to exposure to several environmental pollutants. They are highly reactive species, causing cellular damage and are associated with a plethora of oxidative stress-related diseases and disorders. Antioxidants can control autoxidation by interfering with free radical propagation or inhibiting free radical formation, reducing oxidative stress, improving immune function, and increasing health longevity. Antioxidant functionalized metal nanoparticles, transition metal oxides, and nanocomposites have been identified as potent nanoantioxidants. They can be formulated in monometallic, bimetallic, and multi-metallic combinations via chemical and green synthesis techniques. The intrinsic antioxidant properties of nanomaterials are dependent on their tunable configuration, physico-chemical properties, crystallinity, surface charge, particle size, surface-to-volume ratio, and surface coating. Nanoantioxidants have several advantages over conventional antioxidants, involving increased bioavailability, controlled release, and targeted delivery to the site of action. This review emphasizes the most pioneering types of nanoantioxidants such as nanoceria, silica nanoparticles, polydopamine nanoparticles, and nanocomposite-, polysaccharide-, and protein-based nanoantioxidants. This review overviews the antioxidant potential of biologically synthesized nanomaterials, which have emerged as significant alternatives due to their biocompatibility and high stability. The promising nanoencapsulation nanosystems such as solid lipid nanoparticles, nanostructured lipid carriers, and liposome nanoparticles are highlighted. The advantages, limitations, and future insights of nanoantioxidant applications are discussed.

“…In this manuscript, the Figure of Merit and Sensitivity values are calculated considering the SPR curves [23][24][25][26]. Different dental restorative materials are taken and their bio-compatibility [27,28] with different parts of human teeth are examined in order to verify which dental filling material will be suitable for detecting the sensitivity issues.…”

Dental Restorative materials play a very important role in solving the issue of sensitivity in human teeth. Many such materials, based on their respective optical properties, are considered for various usages viz. cavity treatment, reparation of cracked or broken teeth, detection of plague formation, etc. A new approach to study the suitability of different restorative materials for dentistry application is timely. Surface Plasmon Resonance (SPR), being an optical phenomenon, has the capability to analyze the optical properties which may be used for Bio-medical Applications also. Considering the absorption behavior of Graphene material, the same can also be applied for detecting any plague formation in the essential components of a human teeth viz. Enamel, Dentin and Cementum. Reflectivity, Sensitivity calculations and the correlation between refractive index of different dental restorative materials and their concentration percentage have been tabulated in this manuscript. SPR curves have been obtained using MATLAB environment and Characteristic Transfer Matrix (CTM). The proper explanation of the above is discussed in detail. A new theoretical approach to detect the teeth-health with less-harmful (without X-ray source) technique has been proposed. Graphene layers play an important role as a bio-molecular recognition element and supports the restorative materials to enhance its detection features. A new technique is considered to determine the quality (cavity formation and others) of teeth-hygiene using less health-hazard radiation. LASER beam-based surface plasmon resonance phenomenon is projected here to identify the tooth condition, which will be implemented for the application purpose.
