A review on optical sensors based on layered double hydroxides nanoplatforms

Gold nanoclusters encapsulated into zinc-glutamate metal organic frameworks for efficient detection of H2O2

“…32 As a result, it is crucial for H 2 O 2 detection in clinical, environmental, and pharmaceutical analysis. To date, a variety of analytical methods have been developed for H 2 O 2 detection, including electrochemistry, 33 colorimetry, 34–36 fluorometry 37–39 and so on. Optical methods, in particular, the fluorescence method have aroused great interest of researchers because of the advantages of being simple, fast, easy to operate and convenient.…”

Kadsura-Shaped Covalent–Organic Framework Nanostructures for the Sensitive Detection and Removal of 2,4,6-Trinitrophenol

“…Therefore, a series of fluorescent probes have been developed for TNP sensing. According to the composition and characteristics of probe materials, probes can be mainly divided into three types: nanomaterials, − organic macromolecules, − and organic small molecules. − …”

A dual-responsive nanozyme sensor with ultra-high sensitivity and ultra-low cross-interference towards metabolic biomarker monitoring

“…A single sensor with various optical responses towards multiple analytes could be used to overcome the difficulties associated with inadequate probe loading and signal interference cross-talk encountered by simply incorporating different transducers on a hybrid platform. [8][9][10][11][12][13] To resolve these issues, some promising sensors have been developed for the detection of multiple analytes utilizing a multi-channel sensing strategy. [14][15][16][17][18][19][20] In addition, the integration of these sensing approaches can gain the advantages of multiple reporting units, which avoids the disadvantages of a single-mode sensor, therefore making the result more convincing.…”
