A thiol-containing colorimetric chemosensor for relay recognition of Cu2+ and S2− in aqueous media with a low detection limit

Facile and Green Fabrication of Carrageenan-Silver Nanoparticles for Colorimetric Determination of Cu2+ and S2−

“…High sensitivity and selective determination of cations and anions, particularly toxic ones, such as Cu 2+ and S 2− have received considerable attention due to their potential harm to human health and the environment [1,2]. Copper ion (Cu 2+ ) is an essential trace element for human body, and many physiological processes require its participation [3].…”

Three Novel Zn-Based Coordination Polymers: Synthesis, Structure, and Effective Detection of Al3+ and S2− Ions

“…CCDC 1863388 (1), 1863389 (2), and 1863390 (3) contain the supplementary crystallographic data for the present paper. These data can be obtained free of charge from the Cambridge Crystallographic Data Center via the internet at http://www.ccdc.cam.ac.uk/data_request/cif, or by e-mailing data_request@ccdc.cam.ac.uk.…”

“…As interest in environmental and health concepts grows, the effects of various ions on the biological environment and human health are popular focus points. Aluminum and sulfur ions play an important part in our daily lives and are not able to be substituted due to their peculiarly superior properties, such as the light weight and corrosion resistance of the metal aluminum, and the participation of sulfur ions in physiological processes [1,2]. However, if the aluminum ion or sulfur ion content in the body is high, it will affect human health.…”

A selective sulphur‐containing colorimetric chemosensor for Cu2+

“…Moreover, copper is an essential metal ion in the body and plays diverse roles such as energy production, pigmentation and connective tissue formation. Despite these important roles in various fields, an excessive amount of copper can cause numerous neurodegenerative and neurological diseases such as Alzheimer's disease, amyotrophic lateral sclerosis and Parkinson's disease . Therefore, it is important to develop selective and sensitive sensors for detecting copper …”

“…Despite these important roles in various fields, an excessive amount of copper can cause numerous neurodegenerative and neurological diseases such as Alzheimer's disease, amyotrophic lateral sclerosis and Parkinson's disease. [5][6][7][8][9][10][11] Therefore, it is important to develop selective and sensitive sensors for detecting copper. 12 There are various methods for copper detection, such as flame atomic absorption spectrometry (FAAS), atomic absorption spectrometry and inductively coupled plasma optical emission spectrometer, but they have complicated operations and require pretreatment of the sample prior to determination.…”
