Hexavalent chromium (Cr(vi)) is one of the most toxic heavy metal pollutants in groundwater, and thus the detection of Cr(vi) with high sensitivity, accuracy, and simplicity and low cost is of great importance.
This article reports the novel assembly of a bacteriophage-based fluorescent sensor for the selective and sensitive detection of a model bacterium ‘Staphylococcus arlettae(S. arlettae)’.
A novel water soluble fluorescent sensor was synthesized by employing the carboxyl and imidazolyl moiety as the hydrophilic group site and Hg2+ binding site, whereas a naphthalimide moiety was used as the signal group.
A fluorescent sensor based on aggregation-induced emission for amines was prepared and its highly sensitive detection of hydrazine and application in living cell imaging were investigated in detail.
More than 200 million people in the world are exposed to areas where the arsenic concentration exceeds the limit allowed for living species, which urges people to develop low-cost methods...
Highly reproducible and sensitive detection of small organic pollutants via reduced graphene oxide based ‘turn-on’ fluorescent sensor
