Nanoaggregates of benzothiazole-based amidines were prepared for study as sensors in aqueous medium. Sensor N2 was found to behave as a selective primary sensor for Ag+, and the subsequent complex N2·Ag+ acted as a secondary sensor for Cl− in aqueous medium through a cation displacement mechanism. The cation displacement mechanism was further supported

We have shown within the quasistatic approximation that the giant fluctuations of local electromagnetic field in random fractal aggregates of silver nanospheres are strongly correlated with a local anisotropy factor S which is defined in this paper.

First-principles simulations of the initial phase of self-aggregation of a cyanine dye: structure and optical spectra [PDF]
Using first-principles simulations, we investigated the initial steps of the self-aggregation of the dye pseudoisocyanine (PIC) in water. First, we performed molecular dynamics (MD) simulations of the self-aggregation process, in which pile-of-coins ...

Influence of Graphene Oxide on Asphaltene Nanoaggregates [PDF]
Asphaltenes are a group of exotic hydrocarbons found in bitumen and other forms of heavy crude oil derivatives. These hydrocarbons, with elusive chemistry, give crude oil derivatives (CODs), such as bitumen, its characteristic properties.

STM fluorescence of porphyrin enhanced by a strong plasmonic field and its nanoscale confinement in an STM cavity [PDF]
We have investigated scanning tunneling microscope-induced luminescence STML from porphyrin molecules by varying the tip PtIr, Ag, and Au/substrate Pt, Ag, Au, and indium tin oxide combinations. Strong molecular fluorescence by highest-occupied molecular

Hybrid antibacterial microneedle patches against skin infections [PDF]
Skin and soft tissue infections (SSTIs) are a major healthcare burden that has increased in incidence since the beginning of the 21st century resulting in an annual spending of approximately 15 b$ in 2012 in the United States (US).1 Treatment of SSTIs ...

Nonresonant Surface‐Enhanced Hyper Raman Scattering of Aromatic Amino Acids on Gold Nanoparticles
The surface‐enhanced hyper Raman spectra of the three aromatic amino acids phenylalanine, tryptophan, and tyrosine, obtained with nonresonant excitation at a wavelength of 1064 nm, are reported. The data are discussed in the context of the interaction of the molecules with two gold nanoparticle plasmonic substrates, as well as intermolecular ...
