Heavy metal ions present in water bodies are of great concern for human health, aquatic life,
and environmental sustainability. The heteroatoms present in small organic molecule-based …

The traditional sensors are designed based on the “lock-and-key” strategy with high
selectivity and specificity for detecting specific analytes, which however are not suitable for …

The abnormal concentration of the metal ions in the environment threatens the health of
Earth and human beings. At present, many methods have been employed to detect metal …

Development of highly sensitive and selective sensing systems of divalent zinc ion (Zn2+) in
organisms has been a growing interest in the past decades owing to its pivotal role in …

Supramolecular chemosensor arrays are powerful analytical methods to classify and
quantify analytes using pattern recognition. This Review summarizes approaches based on …

Continuous efforts to produce functional nanomaterials and flexible/stretchable devices
have promoted cumbersome, laboratorial, detection processes toward wearable and …

There is a continuing high demand to design effective sensors for the determination of heavy
metal ions (HMIs) since they are hazardous to both human health and the environment. In …

In this work, we report the synthesis of nitrogen (N)-doped carbon nanodots (N-CNDs) with
an N doping level of 3.6 at.% by hydrothermal treatment of prawn shell and their application …

In the present work, we report a novel colorimetric sensor array for rapid identification of
heavy metal ions. The sensing mechanism is based on the competition between thiols and …

Heavy metal ions (HMIs), including Cu2+, Ag+, Cd2+, Hg2+, and Pb2+ from the environment
pose a threat to human beings and can cause a series of life-threatening diseases …
