Abstract Localized surface plasmon resonance (LSPR) is a nanoscale phenomenon associated with noble metal nanostructures that has long been studied and gained considerable interest in recent years. These resonances produce sharp spectral absorption scattering peaks, along strong electromagnetic near-field enhancements. Over the past decade, advancements fabrication of have propelled significant developments various scientific technological aspects LSPR. One notable application detection molecular interactions near nanoparticle surface, observable through shifts LSPR peak. This document provides an overview this sensing strategy. Given broad expanding scope topic, it impossible to cover every aspect comprehensively review. However, we aim outline major research efforts within field review diverse array relevant literature. We will provide detailed summary physical principles underlying address some existing inconsistencies nomenclature used. Our discussion primarily focus on sensors employ nanoparticles, rather than those utilizing extended, fabricated structures. concentrate where acts as primary mode signal transduction, excluding hybrid strategies like combining fluorescence. Additionally, our examination biological largely pertain label-free methods, use nanoparticles labels or means enhance efficacy label. In subsequent section review, delve into analytical theory underpinning LSPR, exploring its origins dependency material properties metals surrounding refractive index. discuss behavior both spherical spheroidal particles elaborate how response varies particle ratio. Further, detail fundamentals nanoparticle-based sensing. includes exploration single-particle ensemble measurements comparative analysis scattering, absorption, extinction phenomena. The extend these are applied practical scenarios, highlighting key experimental approaches measurement techniques.

Abstract Food crops are attacked by microbial pathogens and insect pests, leading to significant yield reductions economic losses. Conventional disease diagnosis management approaches often fail provide rapid eco-friendly solutions. In the current situation, nanomaterials (NMs) serve a valuable role in both managing emerging monitoring overall plant health. Nanotechnology has transformed biotechnology industry including agriculture with specific applications such as nano-fungicides, nano-bactericides, nano-pesticides. This review focuses on use of various nanomaterials, inorganic materials Ag, ZnO, CuO, CeO, well carbon-based nanoparticles, nanotubes, nanowires, nano-capsules. The application NMs holds potential address challenges food security through novel like advanced nano-biosensors for pathogen detection targeted strategies. includes minimize reliance chemical inputs contribute more sustainable agricultural practices. Nanomaterials promise deliver hormones signaling molecules plants, enhancing resistance inducers against major crop pathogens. newly arising reactive oxygen generation, membrane damage, biochemical interference also reviewed. However, regarding stability, toxicity, environmental impacts discussed, along recommendations green synthesis functionalization approaches. article aims investigate health offering an insightful outlook future generations. Further biosafety aspects larger-scale validation NM-based could enable their commercialization improving global security. Graphical

A tremendous increase in the green synthesis of metallic nanoparticles has been noticed last decades, which is due to their unique properties at nano dimension. The present research work deals with mediated by actinomycete Streptomyces tendae silver (AgNPs), isolated from Little and Greater Rann Kutch, India. confirmation formation AgNPs actinomycetes was carried out using a UV-Vis spectrophotometer where an absorbance peak obtained 420 nm. X-ray diffraction pattern demonstrated five characteristic peaks indexed lattice plane (111), (200), (231), (222), (220). Fourier transform infrared showed typical bands 531 1635, 2111, 3328 cm−1. Scanning electron microscopy shows that spherical-shaped particles have diameters range 40 90 particle size analysis displayed mean aqueous medium, about 55 nm (±27 nm), bearing negative charge on surfaces. potential S. tendae-mediated synthesized evaluated for antimicrobial, anti-methicillin-resistant Staphylococcus aureus (MRSA), anti-biofilm, anti-oxidant activity. maximum inhibitory effect observed against Pseudomonas aeruginosa (8 µg/mL), followed Escherichia coli Aspergillus niger (32 Candida albicans (64 whereas Bacillus subtilis (128 µg/mL) (256 were much less sensitive AgNPs. biosynthesized activity MRSA, free radical scavenging dosage 25 200 µg/mL. combination ampicillin inhibition development biofilm Streptococcus pneumoniae 98% 83%, respectively. also successfully coated surface cotton prepare antimicrobial surgical cotton, action (15 mm) (12 mm). integrates microbiology, nanotechnology, biomedical science formulate environmentally friendly materials halotolerant actinomycetes, evolving nanotechnology field. Moreover, this study broadens understanding opens possibilities formulating new products therapies.
