Cigarettes, despite being economically important legal consumer products, are highly addictive and harmful, particularly to the respiratory system. Tobacco smoke is a complex mixture containing over 7000 chemical compounds, 86 of which are identified to have "sufficient evidence of carcinogenicity" in either animal or human tests. Thus, tobacco smoke poses a significant health risk to humans. This article focuses on materials that help reduce the levels of major carcinogens in cigarette smoke; these include nicotine, polycyclic aromatic hydrocarbons, tobacco-specific nitrosamines, hydrogen cyanide, carbon monoxide, and formaldehyde. Specifically, the research progress on adsorption effects and mechanisms of advanced materials such as cellulose, zeolite, activated carbon, graphene, and molecularly imprinted polymers are highlighted. The future trends and prospects in this field are also discussed. Notably, with advancements in supramolecular chemistry and materials engineering, the design of functionally oriented materials has become increasingly multidisciplinary. Certainly, several advanced materials can play a critical role in reducing the harmful effects of cigarette smoke. This review aims to serve as an insightful reference for the design of hybrid and functionally oriented advanced materials.

“…Although the oncogenic mechanisms of NNK remain debatable, one possible mechanism is that the metabolic products of NNK are capable of forming adducts with DNA. − TSNAs are formed during the growth, curing, storage, and processing of tobacco leaves. − The determination of TSNA concentration during the postharvest period of tobacco can be used for the quality control of tobacco products. An efficient determination method of TSNAs is based on LC/GC–MS/MS along with preconcentration steps. − The preconcentration of TSNAs using an efficient and selective adsorbent is important, especially for samples with a complex matrix and/or low concentration of TSNAs. Moreover, the efficient adsorbent for TSNAs can also be used to extract TSNAs from tobacco waste to reduce the disposal of carcinogenic species into the environment.…”

“…Over the past decades, several adsorbents for TSNAs have been developed based on inorganic porous compounds, graphene aerogels, and imprinted polymers. ,− However, the removal efficiencies for TSNAs are low (the maximum adsorption capacity for NNK is usually lower than 70 mg/g). Therefore, efficient and selective adsorbents for TSNAs are still highly desired.…”

We designed porous polymers with a tungsten-calix[4]arene imido complex as the nitrosamine receptor for the efficient extraction of tobacco-specific nitrosamines (TSNAs) from water. The interaction between the metallocalix[4]arene and the TSNA, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (nicotine-derived nitrosamine ketone, NNK) was investigated. We found that the incorporation of the nitrosamine receptor into porous polymers increased their selectivity toward NNK over nicotine. The polymer with an optimal ratio of calixarene-containing and porosity-inducing building blocks showed a high maximum adsorption capacity of up to 203 mg/g toward NNK under sonication, which was among the highest values reported. The adsorbed NNK could be removed from the polymer by soaking it in acetonitrile, enabling the adsorbent to be reused. A similar extraction efficiency to that under sonication could be achieved using the polymer-coated magnetic particles under stirring. We also proved that the material could efficiently extract TSNAs from real tobacco extract. This work not only provides an efficient material for the extraction of TSNAs but also offers a design strategy for efficient adsorbents.

“…Many MNPs have been used in MSPE. In recent studies carbon‐based MNPs such as carbon nanotubes [14, 15], graphene [10, 16], phenyl [17], fluorenyl [18], porous β‐cyclodextrin polymer [19], C 8 [20], and C 18 [21] were used as sorbents because of their high adsorption capacity.…”

A new version of magnetic solid-phase extraction performed in a narrow-bore tube has been proposed for the extraction and preconcentration of different pesticides from various vegetable and fruit juices followed by gas chromatography. A few milligrams of C 8 @SiO 2 @Fe 3 O 4 nanoparticles are added into an aqueous sample solution placed in a narrow-bore tube. The sorbent particles move down through the tube under gravity and are collected at the end of the tube by applying an external magnetic field. The end of the tube is narrower and it is connected to a stopcock. After a predetermined time, the stopcock is opened and the solution is passed through the bed of the sorbent maintained by the magnet. Then the adsorbed analytes are desorbed using an elution solvent. To achieve high enrichment factors, a dispersive liquid-liquid microextraction method is carried out. The nanoparticles were characterized by scanning electron microscopy, X-ray diffraction, and FTIR spectroscopy. Under the optimum extraction conditions, limits of detection and quantification were in the ranges of 0.1-0.3 and 0.3-0.9 μg/L, respectively. High enrichment factors (1166-1605) and good extraction recoveries (58-80%) were obtained.
