Design and synthesis of a carbohydrate-derived chemosensor for selective Ni(II) ion detection: A turn-off approach.

Nickel, an essential transition metal, plays a vital role in biological systems and industries. However, exposure to nickel can cause severe health issues, such as asthma, dermatitis, pneumonitis, neurological disorders, and cancers of the nasal cavity and lungs. Due to nickel's toxicity and extensive industrial use, efficient sensors for detecting Ni ions in environmental and biological contexts are essential.
