Recent advances in nanomaterials-based optical and electrochemical aptasensors for detection of cyanotoxins

Recent advances in photoelectrochemical platforms based on porous materials for environmental pollutant detection

“…Toxins are harmful compounds produced by living cells or organisms, including microcystin-LR (MC-LR), ochratoxin A (OTA), and aflatoxin B1 (AFB1). 250 Therefore, the development of simple and sensitive methods for detecting such toxins is critical. Recently, Li et al constructed a photoelectrochemical sensor for MC-LR detection, employing a bismuth/two-dimensional graphitic carbon nitride/deoxyribonucleic acid (BiVO 4 /2D-C 3 N 4 /DNA) aptamer system.…”

Electrochemical Detection of Flutamide by the Composite of Complex Based on Thiacalix[4]arene Derivatives and Reduced Graphene Oxide

“…During the detection process, it is very sensitive to interference such as background fluorescence and quenching effect . Electrochemical analysis has attracted much attention because of its advantages of rapid reaction, high sensitivity, portability, and low cost in the detection of FTA. − In recent years, electrochemical sensors have been widely used in the detection of FTA. − Hence, it is attractive to construct an efficient and convenient electrochemical sensor for FTA.…”
