This review covers some recent advances made using boron dipyrromethene (Bodipy) compounds, highlighting aspects such as new sensing applications for reactive oxygen species and solvent rheology. The light-harvesting capabilities of the dye especially in the crystalline state are also discussed emphasising Bodipy deri…
Fluorescent oligonucleotide-stabilized Ag nanoclusters are demonstrated as novel and environmentally-friendly fluorescence probes for the determination of Hg(2+) ions with a low detection limit and high selectivity.
Copper nanoparticles can be utilized as a low-cost replacement for silver and gold nanoparticles which are currently used in inkjet printing of conductive patterns. However, the main obstacle for using copper nanoparticles is their spontaneous oxidation at ambient conditions. Here we describe the synthesis of nonoxidi…
Optical activity and its relation with chiral metal nanoparticles are revised in this tutorial review. The experimental evidence as well as the different mechanisms to explain the optical activity of ligand-protected nanoparticles are described, emphasizing the aspects that provide insights into this novel phenomenon…
In this report, the development of multi-channel anti-Stokes luminescent Y2O3 nanoparticles for application to in vivo upconversion imaging is detailed.
Quantum dots (QDs) are a novel class of inorganic fluorophores, which are gaining widespread recognition as a result of their exceptional photophysical properties. They are rapidly being integrated into existing and emerging technologies, and could play an important role in many areas in the future. Significant phenom…
The relation between the spin-density wave (SDW) and superconducting order is a central topic in the current research on the FeAs-based high- T C superconductors. Conflicting results exist in the LaFeAs(O, F)-class of materials, for which whether the SDW and superconductivity are mutually exclusive or they can coexist…
The use of nanoalloys in catalysis is a rapidly expanding field. There has been immense interest in the use of supported gold nanoparticles as catalysts, and bimetallic catalysts containing gold in combination with other metals represents an emerging field of research. While bulk copper-gold alloys are well-known and,…
This tutorial review illustrates the structural design, photochemical and photophysical properties of nanostructured constructs incorporating luminescent and photochromic components. In these systems, the pronounced structural and electronic modifications that accompany the transformations of the photochromic componen…
Low-molecular-weight gelators form supramolecular gels in organic fluids, aqueous solutions and both organic and aqueous solutions through supramolecular interactions such as hydrogen-bonding, van der Waals, hydrophobic, pi-stacking, coordination, donor-acceptor and charge-transfer interactions. Molecules having chira…
PEGylation is a process in which one or more units of chemically activated polyethylene glycol reacts with a biomolecule, usually a protein, peptide, small molecule or oligonucleotide, creating a putative new molecular entity possessing physicochemical and physiological characteristics that are distinct from its prede…
NiO nanoparticles with average particle size of 25 nm were successfully prepared by anodic arc plasma method. The composition, morphology, crystal microstructure, specific surface area, infrared spectra, and particle size distribution of product were analyzed by using X‐ray diffraction (XRD), transmission electron mic…
A novel fluorescent film was fabricated by doping the aggregates of hexaphenylsilole (HPS) into a chitosan film. It was demonstrated that the fluorescence emission of the film is stable, sensitive and highly selective to the presence of picric acid (PA). The detection limit for PA is about 2.1 × 10−8 mol/L. Introducti…
Nanomaterials are being used increasingly for commercial purposes, yet little is known about the potential health hazards such materials may pose to consumers and workers. Here we show that nano-sized titanium dioxide (TiO2), which is used widely as a photo-catalyst and in consumer products, administered subcutaneousl…
Intrigued by transannular interactions occurring in stacked aromatic molecules, chemists have long endeavored to engineer discrete stacks of specific lengths and orientation. The maturation of self-assembly methodologies has shifted the focus away from utilizing covalent scaffolds to harnessing non-covalent interactio…
Organic–inorganic nanocomposites with high refractive index (RI) are typically constructed by integrating high RI inorganic nanoscale building blocks into a processable, transparent organic matrix. These nanocomposites combine the numerous advantages of organic and inorganic components, and have many promising applica…
Since the late 1990s, sodium borohydride (NaBH4, denoted SB) is presented as a promising hydrogen storage material and an attractive fuel (aqueous solution) of the direct fuel cell (or direct liquid-feed fuel cell). In 2007, the U.S. Department of Energy recommended a no-go for SB for vehicular applications and sugges…
In view of its unique photocatalytic properties, decatungstate (W(10)O(32)(4-)) is rapidly emerging as a promising tool in organic chemistry. This tutorial review surveys recent developments in the chemistry of decatungstate, including mostly synthetic, and to a lesser extent mechanistic aspects. We have chosen to pre…
Gel-phase materials are generated when molecular building blocks assemble into nanoscale architectures, usually 'one-dimensional' fibrils, which hierarchically assemble into bundles and subsequently form an entangled sample spanning network, capable of preventing the flow of bulk solvent. This tutorial review explores…
Phytochemicals occluded in tea have been extensively used as dietary supplements and as natural pharmaceuticals in the treatment of various diseases including human cancer. Results on the reduction capabilities of phytochemicals present in tea to reduce gold salts to the corresponding gold nanoparticles are presented…
