“…At present, the main detection methods of Al 3+ include graphite furnace atomic absorption spectrometry, flame atomic absorption spectrometry and inductively coupled plasma atomic emission spectrometry . However, the technical detection instrumentation is expensive and the operation steps are complicated.…”

As an important metal element, aluminium has a significant impact on the environment and human health, and thus the detection of Al 3+ has become the subject of much research. We synthesized a Ni(II)-based metal-organic gel (Ni-MOG), which can serve as an Al 3+ fluorescence sensor with high selectivity and sensitivity, the limit of detection being calculated to be 0.5 μM. In addition, a composite film was further fabricated by hybridization of this Ni-MOG with poly(vinyl alcohol). The composite film produced a rapid fluorescence response to Al 3+ solutions at concentrations above 5 × 10 −5 M in 5 min. The Ni-MOG composite film can also be successfully applied for the sensitive detection of Al 3+ in real samples of tap water and seawater. The effective detection of Al 3+ described in this contribution provides a new insight into water quality monitoring and has promising application value.

“…The concentration of SiC in the produced water dispersed samples was determined by high-resolution continuum source graphite furnace atomic absorption spectroscopy (HR-CS-GFAAS) using a ContrAA-700 tandem spectrometer (Analytik Jena AG, Jena, Germany) equipped with a transversally heated graphite tube atomizer (THGA). 47 The Si content of the Si USNPs' stock solution was found to be 0.85 mg ml À1 . Assuming that all the Si atoms in the sample are in the form of SiC and from the average diameter of the SiC USNPs, the SiC concentration is 9.7 10 À5 mol l À1 .…”

Ultrasmall silicon carbide nanoparticles (SiC USNPs) are very promising biomarkers for developing new applications in diagnostics, cell monitoring or drug delivery, even though their interaction with biological molecules such as different proteins has not yet been investigated in detail. In this study, the biological behaviour of SiC USNPs in a medium modeling a living organism was investigated in detail through the dependence of the fluorescence on interactions between bovine serum albumin (BSA) and SiC USNPs. The interaction shows transient nanoparticle-protein associations due to the restricted diffusion behaviour of the nanoparticles in the vicinity of a protein. The transient association manifests in a complex fluorescence quenching mechanism where the dynamic component was dominated by Förster resonance energy transfer. By studying SiC nanoparticles of different sizes, it can be concluded that the transient effect is an ultrasmall nanoparticle behaviour.

“…From a methodological point of view, practically all that was discussed in the review mentioned before 21 holds true. The technique has shown potential to analyze very different types of materials, from some that could be considered as relatively easy for graphite furnace decomposition, such as polymers, biological materials or pharmaceuticals, to others that are quite refractory and, also, very difficult to bring into solution quantitatively, such as automobile catalysts, 24 fertilizers, 25 high-purity silicon 26 or silicon carbide, 27 in addition to many types of environmental samples.…”
