“…Hybrid nanostructures consisting of metal nanoparticles, organic dyes, fluorophores, and oligonucleotides are of recent attraction for various applications such as bioassays (You et al 2007;Mayilo et al 2009;Pramanik et al 2008), biosensors (You et al 2007), biophotonics (Pramanik et al 2008;Dulkeith et al 2002), and biomedicals (Kuo et al 2012;Zhang et al 2012). However, gold nanoparticles (GNPs) based composite structures have been receiving considerable attention owing to their stability, biocompatibility, dimensional similarities with biomolecules, and non-toxicity (Pramanik et al 2008;Kuo et al 2012;Alexandridis 2011).…”

As the fluorescence quenching technique is an effective method for the study of mechanism of molecular interactions such as excited state interaction and ground-state complex formation, energy and charge transfer, it has been widely used to gather information about biochemical systems (Lakowicz 1999).…”

We study the quenching of fluorescence intensity of 40 g/L poly(vinyl pyrrolidone) PVP molecules by varying the content of gold nanoparticles (GNPs) from 1 to 5 lM in 1-butanol. A profound exponential decay of the emission band intensity in the p / np* band of the PVP molecules at *392 nm upon gradual addition of the GNPs demonstrates an existence of an excited state interaction of NPs with the PVP molecules in a gold colloid in 1-butanol. Such quenching is caused by the non-bonding electron transfer from the O-atom of carbonyl group of the PVP molecules to the surface of the GNP. X-ray photoemission spectroscopy (XPS) study corroborates the spectroscopic results. A linear Stern-Volmer plot with a quenching constant of 2.23 9 10 6 M -1 reveals dynamic quenching in a non-aqueous NF. A mechanism of fluorescence quenching was proposed in support of XPS and images taken from hybrid nanostructure using transmission electron microscope. Study on quenching of fluorescence intensity of PVP fluorophore in the presence of GNPs is useful for optoelectronic devices and biosensors.

“…3,7,25,38,48 The type of Laser applied in most of the investigations was NIR with wavelength spectra of 785 nm up to 1046 nm, 4,7,10,15,21,39,40,56,59 with 808 nm wavelength used more frequently. 10,20,25,29,34,41,49,62,72 As mentioned earlier, the 808 nm wavelength was the most effective in studies aiming at photothermal destruction of cancer cells. The absorption peak of gold nanoparticles can be modulated by creating different shapes and size.…”

“…The dye-doped silica NPs are usually synthesized by a sol-gel St ö ber process or in microemulsion by simply adding the dye (or a modified form of the dye) to the silicaforming solution [123] . In addition, the use of mesoporous silica NPs enables the loading of additional functions into the resulting pores, for example, the imaging probes of sentinel lymph nodes (SLNs) known as the first defense against primary tumor metastasis [124] , sensing [125] , or a therapeutic agent capable of photothermal ablation (PTA) or a controlled drug release [126] . The covalent chemical grafting of the lanthanide complexes on the metal oxide NPs was also recently performed, and the introduction of two different lanthanides gave bimodal CAs [64,65,127] .…”

Abstract:The successful development of nanomaterials illustrates the considerable interest in the development of new molecular probes for medical diagnosis and imaging. Substantial progress was made in the synthesis protocol and characterization of these materials, whereas toxicological issues are sometimes incomplete. Nanoparticlebased contrast agents (CAs) tend to become efficient tools for enhancing medical diagnostics and surgery for a wide range of imaging modalities. The multimodal nanoparticles (NPs) are much more efficient than the conventional molecular-scale CAs. They provide new abilities for in vivo detection and enhanced targeting efficiencies through longer circulation times, designed clearance pathways, and multiple binding capacities. Properly protected, they can safely be used for the fabrication of various functional systems with targeting properties, reduced toxicity, and proper removal from the body. This review mainly describes the advances in the development of mono-to multimodal NPs and their in vitro and in vivo relevant biomedical applications ranging from imaging and tracking to cancer treatment. Besides the specific applications for classical imaging (magnetic resonance imaging, positron emission tomography, computed tomography, ultrasound, and photoacoustic imaging), the less common imaging techniques such as terahertz molecular imaging (THMI) or ion beam analysis (IBA) are mentioned. The perspectives on the multimodal theranostic NPs and their potential for clinical advances are also mentioned.
