“…Carbon-based conjugates of siloxanes in the form of carbon dots, graphene sheets, and multi-walled carbon nanotubes could be examples because of the unique properties of carbon materials. For instance, carbon dots, graphene quantum dots, and carbon quantum dots were used as initial materials for conjugation with tetraethoxysilane and (3-aminopropyl)triethoxysilane to obtain specific photoluminescence materials [ 155 , 156 , 157 ]. In another paper, Li and co-workers [ 158 ] elaborated on a siloxane composite of reduced graphene oxide and tetraethoxysilane/3-(aminopropyl)triethoxysilane with silver nanoparticles as support for modification with a polydopamine layer.…”

Molecular imprinting technology is a well-known strategy to synthesize materials with a predetermined specificity. For fifty years, the “classical” approach assumed the creation of “memory sites” in the organic polymer matrix by a template molecule that interacts with the functional monomer prior to the polymerization and template removal. However, the phenomenon of a material’s “memory” provided by the “footprint” of the chemical entity was first observed on silica-based materials nearly a century ago. Through the years, molecular imprinting technology has attracted the attention of many scientists. Different forms of molecularly imprinted materials, even on the nanoscale, were elaborated, predominantly using organic polymers to induce the “memory”. This field has expanded quickly in recent years, providing versatile tools for the separation or detection of numerous chemical compounds or even macromolecules. In this review, we would like to emphasize the role of the molecular imprinting process in the formation of highly specific siloxane-based nanomaterials. The distinct chemistry of siloxanes provides an opportunity for the facile functionalization of the surfaces of nanomaterials, enabling us to introduce additional properties and providing a way for vast applications such as detectors or separators. It also allows for catalyzing chemical reactions providing microreactors to facilitate organic synthesis. Finally, it determines the properties of siloxanes such as biocompatibility, which opens the way to applications in drug delivery and nanomedicine. Thus, a brief outlook on the chemistry of siloxanes prior to the discussion of the current state of the art of siloxane-based imprinted nanomaterials will be provided. Those aspects will be presented in the context of practical applications in various areas of chemistry and medicine. Finally, a brief outlook of future perspectives for the field will be pointed out.

“…Many chromatographic methods have been developed so far for the separation and quantification of ATP and other neonicotinoids residues in various matrices. For instance, GC [15] and LC‐MS [3,9,16,17] are sensitive and reliable techniques but their high cost, nonportable characteristics, need of skilled technicians, matrix effect, and need of chemical derivatization of polar analytes, such as ATP in GC, make these unsuitable for the routine analysis of pesticide residues in various matrices [2,4,5,7,18]. Whereas, conventional HPLC equipped with UV or DAD is a commonly used alternative technique because of its low cost and versatility [3,8,10,14].…”

This study aims to introduce a simple, sensitive, and cost-effective method for the simultaneous determination of acetamiprid and its main metabolite 6-chloronicotinic acid in environmental samples by using a nonsuppressed ion chromatography hyphenated with an online postcolumn photoinduced fluorescence detection system. The fluorescence detector wavelengths λ ex /λ em = 257/382 nm was set for up to 6.0 min for acetamiprid, while λ ex /λ em = 231/370 nm programmed for 6-chloronicotinic acid for the rest of the analysis time. Both samples were treated by applying miniaturized quick, easy, cheap, effective, rugged, and safe method before the separation of analytes on an IonPac R AS11-HC column by pumping 40 mM NaOH having minuscule content of acetonitrile (5%, v/v) as an eluent. Both intrinsically nonfluorescent analytes were turned-on by online postcolumn photoinduced derivatization, avoiding the need for complex chemical derivatization or addition of a postcolumn extra pump. The developed method was appraised for the analysis of environmental samples, exhibiting excellent linearity (0.050-10 μg/mL) with a correlation coefficient greater than 0.9993 for both analytes. Whereas, obtained limit of detection (0.025-0.0072 μg/mL), recoveries (98.02-116.00%), and inter-and intraday
