Green fluorescent carbon dots functionalized MoO3 nanoparticles for sensing of hypochlorite

Recent advances in nanomaterials‐based optical sensors for detection of various biomarkers (inorganic species, organic and biomolecules)

“…[ 108,109 ] The optically activated metal‐oxide NPs are also used for the detection of numerous analytes such as anions, metal ions, biomolecules, or some other due to the advantages of fluorogenic and chromogenic based biosensors, simplicity, selectivity and great sensitivity, sensing and biosensing with optically active metal‐oxide nanomaterials. [ 107 ] For instance, titanium dioxide (TiO 2 ) is a potent photocatalyst; Fe 3 O 4 is a non‐toxic magnetic compound that can be used for drug administration and separation whereas cerium(IV) oxide (CeO 2 ) is an essential oxidative catalyst. [ 110 ] For the fluorescence and colorimetric detection of biomarkers, metal oxide NPs such as Fe 3 O 4 , cobalt(II,III) oxide (Co 3 O 4 ), and bimetallic oxide NPs such as magnesium ferrite (MgFe 2 O 4 ) are being researched.…”

Recent developments in carbon dot-based green analytical methods: new opportunities in fluorescence assays of pesticides, drugs and biomolecules

“…Furthermore, there are several merits of CDs such as low approach for assaying a wide variety of target analytes with improved sensitivity and as a potential candidate for bioimaging and biomedical applications. [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] To date, different fluorescent color CDs have been prepared and integrated with fluorescence spectroscopy for assaying various analytes. 1,28 According to the reported literature, several reviews have summarized the recent developments in the synthetic strategies and properties of CDs.…”

“…16 On the other side, the fluorescence sensing application is widely used to overcome these issues with the merits of high sensitivity, transportability, low cost, and less detection time. 17 However, previous reviews [18][19][20][21][22][23][24][25][26][27][31][32][33] have discussed the synthetic strategies and applications of CDs in bioimaging, bioanalysis, and energy conservation. They either emphasized the topic to be limited or outmoded and examined it from various perspectives.…”

Ultra-bright green carbon dots with excitation-independent fluorescence for bioimaging

“…More recently, carbon dots (CDs) have become a popular choice as an imaging agent due to their remarkable biocompatibility and proven biodegradation compared to other inorganic semiconductor quantum dots [27][28][29][30]. The fluorescent organic CDs are among the emerging low-cost and promising imaging agents due to their tuneable surface functionality, unique optical properties (e.g.…”

“…The fluorescent organic CDs are among the emerging low-cost and promising imaging agents due to their tuneable surface functionality, unique optical properties (e.g. excitation dependent emission), and the ability to use a range of low-cost materials or bio-waste materials as starting precursors for their synthesis [30][31][32].…”
