“…These nanoparticles possess advantageous properties such as better photostability, improvised low detection limits, localized detection, high quantum yield, and clinical applicability [18,19]. Suitably functionalized silver NPs are considered as efficient nano probe in bioimaging [20]. Metallic nanoparticles can also be used as imaging agents with high X-ray contrast because of their potency to absorb X-ray radiations.…”

This chapter will provide an overview of different nanomaterials, which are being used for nondestructive imaging of living entities such as cells and tissues. The chapter begins with the basics of fluorescence imaging followed by a discussion on the advantages of fluorescent nanomaterials as compared to commonly used molecular fluorophores and imaging probes. Specific features and applications of nanomaterials frequently exploited in bioimaging are summarized. These include fluorescent silicon-based nanomaterials, hydrogels, polymer dots, magnetic nanoparticles, fluorescent quantum dots, carbon dots and other carbon-based nanomaterials, noble metal nanoparticles, micelles, dendrimers, lipid nanoparticles, and so on. Specific examples on their applications in bioimaging including multimodal imaging and targeted imaging are illustrated.

“…Nanoparticles (NPs) are particles that range 1-100 nm in size. Green synthesized silver nanoparticles (AgNPs) are widely studied metal among other MNPs and e ciently utilized in a wide range of scienti c and industrial applications including catalysis [9], sensing, molecular imaging [10], electronics [11], antimicrobial [12], therapeutics [13], tissue engineering [14], solar cells [15], drug and gene delivery [16], wastewater remediation [17], etc. Notably, absorption and scattering plasmonic spectra (colors) of colloidal gold nanoparticles (AuNPs) and AgNPs have been used as colorimetric assays for sensing of DNA, proteins and metal ions using the naked eye, showing the importance of design of colors (absorption and scattering optical properties) of colloidal NPs [18].…”

Scope of green chemistry in nanobiotechnology is generating research interest in the development of an ecofriendly synthesis of nanoparticles and their wide range of applications in engineering and biomedical field. In the present study, we report a simple and ecofriendly phytosynthesis of silver nanoparticles (AgNPs) using Ají amarillo chilli (Capsicum baccatum L.) fruit, where phytoconstituents of C. baccatum behaves as a reducing as well as a stabilizing agent. The phyotsynthesized AgNPs were characterized through various spectroscopic and microscopic techniques. The produced AgNPs showed surface plasmon resonance (SPR) at λmax = 458 nm and stable for 10 days, confirmed by UV-vis spectroscopy. Transmission electron microscopy (TEM) explained that produced AgNPs were almost spherical in shape with average size of 10-30 nm along with small aggregation. Aggregation of AgNPs was indicated in the dynamic light scattering (DLS) analysis. The results also demonstrate that as-synthesized AgNPs are low-cost and rapid alternative as optical chemical sensors and showed >50% H2O2 quenching/ sensing activity for 15 mins at room temperature.
