Constructing carbon dots and CdTe quantum dots multi-functional composites for ultrasensitive sensing and rapid degrading ciprofloxacin

Recent Advances in the Applications of Carbon Nanostructures on Optical Sensing of Emerging Aquatic Pollutants

“…This probe detected tetracycline (fluorescence enhancement) in the concentration range of 0–3.5 μg/mL with a LOD of ∼5.2 ng/mL. A ratiometric sensor was designed to detect CIP based on the CD‐riboflavin hybrids [111] . In this work, dual‐emissive CDs were designed by post‐synthetic addition of riboflavin.…”

“…The sensor has demonstrated a low detection limit ∼0.0127 nM with a linear range of 0–60 nM. Further, the TiO 2 /CDs/CdTe QDs system has been proposed for the photocatalytic degradation of CIP [111] …”

“…A ratiometric sensor was designed to detect CIP based on the CD-riboflavin hybrids. [111] In this work, dual-emissive CDs were designed by post-synthetic addition of riboflavin. The blue emission was enhanced in the presence of ciprofloxacin due to hydrogen bond interaction and conjugate effect.…”

“…Further, the TiO 2 /CDs/CdTe QDs system has been proposed for the photocatalytic degradation of CIP. [111] Recently, aptamer-based biosensors have attracted growing interest in detecting a wide range of environmentally relevant analytes. [112] Aptamers are single-stranded oligonucleotides with a specific binding affinity toward target molecules.…”

A signal-on fluorescent aptasensor based on gold nanoparticles for kanamycin detection

“…[8][9][10] There are also many new methods that have emerged with the development, such as colorimetry, uorescence, electrochemistry, chemiluminescence, electrochemiluminescence, photoelectrochemistry etc. [11][12][13][14][15][16][17][18][19] Fluorescence analysis is characterized by high sensitivity and selectivity. It plays an important role in the preparation of chemical and biological sensors for the detection and analysis of heavy metals, drugs, and biomarkers.…”
