Dual Functional Fluorescent Chemosensor for Discriminative Detection of Ni2+ and Al3+ Ions and Its Imaging in Living Cells

“…Nickel and aluminum have been of great importance in the fields of medicine, the environment, and industrial applications. − Among them, Nickel is an important nutrient used for biosynthesis, respiration, and metabolism related biological processes. Nickel is commonly found in the environment due to a variety of industrial applications like electroless nickel plating, electronics’ cleaning, electrochromic devices, rechargeable batteries, supercapacitors, and precursor for many catalysts. − However, overexposure to this metal by inhalation subsequently has adverse effects on respiratory systems, blood, kidneys, and lungs and causes allergies, asthma, carcinogenesis, central nervous system (CNS) disorder, and nasal cavity related diseases. − In addition, nickel compounds are group one carcinogens with regard to human health, which are classified by the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO). − Nevertheless, the recognition of Ni 2+ has been challenging because of its strong hydration and weak coordinating complexation ability, interference from other metal ions, and its fluorescence quenching properties associated with the paramagnetic nature of Ni­(II). − …”

Solvent-regulated fluorescence off–on signaling of Ni(ii) and Zn(ii) with the formation of two mononuclear complexes with an ATP detection ability by Zn(ii) assembly

“…It is a crucial nutrient required for biological functions like biosynthesis, respiration, and metabolism. [27][28][29] A nickel overload in a person's body affects the blood and kidneys negatively and damages the nerve tissues. Nickel exposure through breathing can seriously endanger human health.…”

A cross-linkable phthalonitrile derivative as a precursor to synthesize nitrogen-doped carbon nanodots for Ni ion detection

“…As an important metal element, nickel is considered as one of the most essential trace elements used by plants and microorganisms in various biological pathways, such as biosynthesis, respiration and metabolism. [1][2][3] At the same time, nickel is also widely used in diverse industrial scenarios, such as metallurgical industry, nickel-chromium batteries, electronic equipment, catalysis and electroplating. [1][2][3][4][5][6] However, the exposure of highly concentrated Ni would result in a series of health problems, such as sinusitis, asthma, acute pneumonia, lung cancer and central nervous system disease (CNS).…”
