“…Due to their unique photochemical and photophysical capabilities, quantum dots (QDs) as zero-dimensional nanostructures have garnered considerable attention. According to the quantum mechanics’ wave-particle duality hypothesis, QDs are nanoscale crystal materials with characteristics between bulk materials and discrete atoms [ 97 ]. According to Chen et al [ 98 ], a simple and environmentally acceptable technique for producing water-dispersible N-doped SiQDs using wheat straw and AMIMCl has been developed.…”

In recent years, there has been much interest in developing advanced and innovative approaches for sensing applications in various fields, including agriculture and environmental remediation. The development of novel sensors for detecting heavy metals using nanomaterials has emerged as a rapidly developing research area due to its high availability and sustainability. This review emphasized the naturally derived and engineered nanomaterials that have the potential to be applied as sensing reagents to interact with metal ions or as reducing and stabilizing agents to synthesize metallic nanoparticles for the detection of heavy metal ions. This review also focused on the recent advancement of nanotechnology-based detection methods using naturally derived and engineered materials, with a summary of their sensitivity and selectivity towards heavy metals. This review paper covers the pros and cons of sensing applications with recent research published from 2015 to 2022.

“…QDs show good luminescence properties compared to organic and inorganic nanoparticles 45,[67][68][69][70][71] . The emission wavelength of QDs can be modified via the changing in QDs' particle size or by selecting a suitable light source for excitation [72][73][74][75][76] . QDs exhibit a narrow, tunable, and symmetric emission spectrum compared to organic fluorophores 77,78 .…”

Cadmium sulfide (CdS) quantum dots (QDs) were homogeneously embedded into chitosan (CTS), denoted as CdS/CTS, via an in-situ solvothermal method. The intact structure of the synthesized materials was preserved via separating the materials using freeze-drying. The materials were characterized using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscope (TEM), high-resolution TEM (HR-TEM), scanning TEM (STEM), dispersive energy X-ray (EDX) for elemental analysis and mapping, Fourier transform infrared (FT-IR), nitrogen adsorp-tion-desorption isotherms, thermogravimetric analysis, UV-Vis spectroscopy, and diffuse reflectance spectroscopy (DRS). The synthesis procedure offered CdS QDs with 1-7 nm (average particle size of 3.2 nm). The functional groups of CTS modulate the in-situ growth of CdS QDs and prevent the agglomeration of CdS QDs, offering homogenous distribution inside CTS. CdS/CTS QDs can also be used for naked-eye detection of heavy metals with high selectivity toward copper (Cu2+) ions. The mechanism of interactions between Cu2+ ions and CdS/CTS QDs was further studied

“…Recently, synthesized metal-organic frameworks were applied for the sensitive luminescence detection of different antibiotics [49][50][51][52][53]. Various biosensors (with aptamer, antibody, molecularly imprinted polymers and dual recognition systems) [54] and sensors modified with metal-based and carbon-based quantum dots, which were developed and applied for colorimetric, photoelectrochemical, photo-, chemi-and electrochemiluminescence detection of residual antibiotics in food products, were reviewed [55]. All these methods are very sensitive and selective but tedious, time and reagent-consuming.…”

Recent Trends in the Development of Carbon-Based Electrodes Modified with Molecularly Imprinted Polymers for Antibiotic Electroanalysis

Antibiotics are antibacterial agents applied in human and veterinary medicine. They are also employed to stimulate the growth of food-producing animals. Despite their benefits, the uncontrolled use of antibiotics results in serious problems, and therefore their concentration levels in different foods as well as in environmental samples were regulated. As a consequence, there is an increasing demand for the development of sensitive and selective analytical tools for antibiotic reliable and rapid detection. These requirements are accomplished by the combination of simple, cost-effective and affordable electroanalytical methods with molecularly imprinted polymers (MIPs) with high recognition specificity, based on their “lock and key” working principle, used to modify the electrode surface, which is the “heart” of any electrochemical device. This review presents a comprehensive overview of MIP-modified carbon-based electrodes developed in recent years for antibiotic detection. The MIP preparation and electrode modification procedures, along with the performance characteristics of sensors and analytical methods, as well as the applications for the antibiotics’ quantification from different matrices (pharmaceutical, biological, food and environmental samples), are discussed. The information provided by this review can inspire researchers to go deeper into the field of MIP-modified sensors and to develop efficient means for reliable antibiotic determination.
