“…Fluorescent nanomaterials have recently attracted considerable attention owing to their tremendous potential applications in various elds including bioimaging, 1,2 chemo/biosensing, [2][3][4][5][6] photocatalysis, 2,7,8 optoelectronic devices, 2,9 and so on. However, the traditional heavy metal-based quantum dots (QDs), such as CdTe, CdSe and CdS QDs, suffer from the toxicity of these heavy metal ions.…”

Nitrogen and boron doped carbon quantum dots (NB-CQDs) with yellow-green emission were prepared via hydrothermal method using 2-hydroxyphenylboronic acid and ethylenediamine in aqueous solution.The as-prepared NB-CQDs exhibited bright yellow-green emission, excellent stability in aqueous solution with high ionic strength and good biocompatibility. We further explored the applications of NBCQDs for sensing metal ions in aqueous solution. We found that the NB-CQDs could be utilized to sense Cr 2 O 7 2À in aqueous solution due to the Cr 2 O 7 2À-induced fluorescence quenching. In the sensing system, as low as 0.5 mM Cr 2 O 7 2À can be successfully detected and a good linear relationship in the range of 0-250 mM has been obtained. And the NB-CQDs can be also used as ink for writing on paper, revealing the NB-CQDs can be applied for anti-counterfeiting. Moreover, the NB-CQDs exhibit negligible cytotoxicity and good biocompatibility, which is favorable for bioimaging applications. And the NB-CQDs were successfully applied for fluorescence imaging in HeLa cells.

“…Such materials can include carbon nanotubes, 1,2 nanorods 3 and nanoparticles of copper 4 , gold, 5 magnetic, 6 and silica. 7 These systems can be designed to produce a signal upon binding to the metal ion or integrated into detection platforms such as atomic adsorption, [8][9][10][11] electrochemical assays, 1,12,13 fluorescence 4,14 and colorimetric sensors 15,16 . Whilst each technology platform has its merits, not all are portable, simple to use/interpret and can require expensive equipment and/or additional gas/carrier liquids.…”

Additional Information:• This paper was accepted for publication in the journal ) from solution. By tuning the pH and ionic strength of the solution, a biphasic pulse, a conductive followed by a resistive pulse is recorded. Biphasic pulses are becoming a powerful way to characterise materials, and provide an insight into the translocation mechanism, and here we present their first use to detect the presence of metal ions in solution. We demonstrate how combinations of translocation speed and/ or biphasic pulse behaviour are used to detect Cu

Metal nanoprobes have recently attracted board research interestinr their application in establishing sensing systems due to their unique optical, electrical, physical, and chemical properties. In comparison to gold and silver nanoprobes, analytical platform based on copper nanoprobes (Cu‐NPs) is still in the early stages of development. In this review, we focus on single‐stranded, and double‐stranded DNA capped Cu‐NPs sensing systems which have been designed for various analytes, including metal ions, anions, small molecules, biomolecules (DNA, RNA, and protein, etc.). In addition, the application of Cu‐NPs in biological labeling or bio‐imaging platforms has also been introduced and summarized.
