Chitosan-functionalized magnetic peanut shell biochar composite for efficient adsorptive removal of Congo red from aqueous solution.

Synthetic dye discharge into aquatic systems has become an escalating environmental concern because these colorants are chemically recalcitrant, toxic, and resistant to biodegradation. In the present study, a Chitosan-functionalized magnetic peanut shell biochar composite (CS-MPSB) was engineered as an economical, biom...

Synergistic oxygen vacancies and mixed-valence states in SrO/MnO2 nanozyme for trace-level ascorbic acid detection in real human serum and different fresh food samples

Aggregation and surface-state modulated fluorescence quenching of lemon-derived carbon quantum dots for the sensitive detection of 4-aminophenol

4-Aminophenol (4-AP) is the primary degradation product of paracetamol (PA), resulting from its hydrolytic cleavage within the human body and is known for its nephrotoxic, hepatotoxic, and teratogenic nature. Its enhanced levels may cause mutagenic responses and DNA damage in living organisms; therefore, the accurate d...
