“…Then, Arslan et al [127] developed CDs of ion-imprinted polymers for ion detection of Pd (II). Subsequently, researchers have developed a sol-gel process using nicotinic acid, [128] bisphenol A, [122] caffeic acid, [58] acetamiprid, [129] phenobarbital, [130] zearalenone, [131] thiabendazole, [132] amphotericin, [133] 4nitrophenol, [54] cetirizine, [134] quinoline, [135] florfenicol, [136] celecoxib, [137] and chloramphenicol [138] as template molecules for the preparation of CD-MIPs polymer molecules (some of the synthetic routes are shown in Figure 11). They all showed good performance in terms of the corresponding specific recognition.…”

Carbon dots (CDs) are a newly discovered type of fluorescent material that has gained significant attention due to their exceptional optical properties, biocompatibility, and other remarkable characteristics. However, single CDs have some drawbacks such as self‐quenching, low quantum yield (QY), and poor stability. To address these issues, researchers have turned to organosilicon, which is known for its green, economical, and abundant properties. Organosilicon is widely used in various fields including optics, electronics, and biology. By utilizing organosilicon as a synthetic precursor, the biocompatibility, QY, and resistance to self‐quenching of CDs can be improved. Meanwhile, the combination of organosilicon with CDs enables the functionalization of CDs, which significantly expands their original application scenarios. This paper comprehensively analyzes organosilicon in two main categories: precursors for CD synthesis and matrix materials for compounding with CDs. The role of organosilicon in these categories is thoroughly reviewed. In addition, the paper presents various applications of organosilicon compounded CDs, including detection and sensing, anti‐counterfeiting, optoelectronic applications, and biological applications. Finally, the paper briefly discusses current development challenges and future directions in the field.

“…The most important limitation of QDs utility is the toxicity of material as a consequence of employment of core heavy atoms (surface oxidation, photodegradation) or hazardous reagents introduced during their preparation process-silanization and A different, more environmentally friendly solution in the field of nanomaterials was proposed by Shirani et al, 2019. The authors described a novel approach in the field of optical sensor based on silane-doped carbon dots (Si-CDs) covered with suitable imprinted polymer for selective detection of acetamiprid in environmental and agricultural samples [48]. At the beginning, the raw nanomaterials Si-CDs were synthetized in stainlesssteel autoclave (heated at 180 • C for 4 h) using 500 µL of APTES combined with 1.0 g of citric acid and 15 mL of deionized water.…”

In the case of quantitative and qualitative analysis of pesticides in environmental and food samples, it is required to perform a sample pre-treatment process. It allows to minimalize the impact of interferences on the final results, as well as increase the recovery rate. Nowadays, apart from routinely employed sample preparation techniques such as solid-phase extraction (SPE) or solid-phase microextraction (SPME), the application of molecularly imprinted polymers (MIPs) is gaining greater popularity. It is mainly related to their physicochemical properties, sorption capacity and selectivity, thermo-mechanical resistance, as well as a wide range of polymerization techniques allowing to obtain the desired type of sorption materials, adequate to a specific type of pesticide. This paper targets to summarize the most popular and innovative strategies since 2010, associated with the MIPs synthesis and analytical procedures for pesticides determination in environmental and food samples. Application of multi-criteria decision analysis (MCDA) allows for visualization of the most beneficial analytical procedures in case of changing the priority of each step of analysis (MIPs synthesis, sample preparation process—pesticides extraction, chromatographic analysis) bearing in mind metrological and environmental issues.

Nanoparticles possess fascinating properties and applications, and there has been increasing critical consideration of their use. Because carbon is a component with immaterial cytotoxicity and extensive biocompatibility with different components, carbon nanomaterials have a wide scope of potential uses.Carbon nanodots are a type of carbon nanoparticle that is increasingly being researched because of their astounding properties such as extraordinary luminescence, simplicity of amalgamation and surface functionalization, and biocompatibility. Because of these properties, carbon nanodots can be used as material sensors, as indicators in fluorescent tests, and as nanomaterials for biomedical applications. In this review, we report on the ongoing and noteworthy utilization of carbon quantum dots such as bioimaging tests and photocatalytic applications. In addition, the extension and future components of these materials, which can be investigated for new potential applications, are discussed.
