Special Issue Information

Dear Colleagues,

For the past few decades, the detection of chemically-important analytes has been a concept of innovative research. In this light, chemical sensors based on nanomaterials seem to be attractive in terms of their applicability in environmental and biological studies. Moreover, chemical nanosensors also attracted the industrial world due to their emerging applications. Nanomaterial-based chemical sensors may include a wide variety of candidates, such as fluorescent nanoparticles, plasmonic nanoparticles, organometallic nano-architectures, up-conversion nanoparticles, nanocrystals, nano dots of silica, carbon and semiconductor materials, metal nanoclusters, nanocomposites, and nanostructures biomolecules. The aforementioned candidates have already been applied in the detection of metal ions, anions, pHs, amino acids, proteins, and so on. However, the mechanism behind diverse analyte detection may vary according to the involved forces.

The purpose of this Special Issue is to provide the up to date information on “Nanomaterial Based Chemical Sensors” and to scrutinize the state-of-the-art methods for the development of such nanosensors towards diverse analyte determination. The major scope of this issue will cover chemical sensory applications of fluorescent and plasmonic nanoparticles, metal nanoclusters, nano dots of silica, carbon and semiconductor materials, and nanocomposites. However, sensory applications of other kind of nanomaterials are also encouraged for submission.

The electro-reduction of nitrate ions in artificial sea water was investigated at a gold substrate (EAu) functionalized by silver nanoparticles (AgNPs). These AgNPs were generated in situ on the gold substrate by the direct decomposition of the metalorganic N,N′-diisopropylacetamidinate silver precursor [Ag(Amd)] in the liquid phase. Very small and well dispersed AgNPs were deposited on the gold electrode and then used as working electrode (EAu/AgNPs). Square wave voltammetry (SWV) was successfully employed to detect nitrate ions (NO3) with a detection limit (LOD) of 0.9 nmol∙L−1 in artificial sea water (pH = 6.0) without pre-concentration or pH adjustment.

Illegal adulteration of milk products by melamine and its analogs has become a threat to the world. In 2008, the misuse of melamine with infant formula caused serious effects on babies of China. Thereafter, the government of China and the US Food and Drug Administration (FDA) limited the use of melamine of 1 mg/kg for infant formula and 2.5 mg/kg for other dairy products. Similarly, the World Health Organization (WHO) has also limited the daily intake of melamine of 0.2 mg/kg body weight per day. Many sensory schemes have been proposed by the scientists for carrying out screening on melamine poisoning. Among them, nanomaterial-based sensing techniques are very promising in terms of real-time applicability. These materials uncover and quantify the melamine by means of diverse mechanisms, such as fluorescence resonance energy transfer (FRET), aggregation, inner filter effect, surface-enhanced Raman scattering (SERS), and self-assembly, etc. Nanomaterials used for the melamine determination include carbon dots, quantum dots, nanocomposites, nanocrystals, nanoclusters, nanoparticles, nanorods, nanowires, and nanotubes. In this review, we summarize and comment on the melamine sensing abilities of these nanomaterials for their suitability and future research directions. Full article
