“…With many of their intrinsic molecular properties and multifunctionality, different nanomaterials have recently become an exciting tool in cancer theranostic applications, assisting in successful therapy, diagnosis, and imaging . However, several obstacles prevent their clinical translation, including systemic toxicity of nanomaterials within the body, nontargeted distribution, complex synthesis, high cost, reduced biocompatibility, stability and reduced photostability. , Another major obstacle to the use of nanomaterials in cancer theranostics is the selection of models as most of the research is in and around cell and animal models that may not be the right models to assess the anticancer efficacy of both diagnostic and therapeutic agents, as these models suffer from various degrees of different chemical and physical stresses and might not be representative of those of whole human organs. In the complex human system, it is difficult to replicate a reaction using just one model.…”

Cancer is ranked as the second leading cause of death globally. Traditional cancer therapies including chemotherapy are flawed, with off-target and on-target toxicities on the normal cells, requiring newer strategies to improve cell selective targeting. The application of nanomaterial has been extensively studied and explored as chemical biology tools in cancer theranostics. It shows greater applications toward stability, biocompatibility, and increased cell permeability, resulting in precise targeting, and mitigating the shortcomings of traditional cancer therapies. The nanoplatform offers an exciting opportunity to gain targeting strategies and multifunctionality. The advent of nanotechnology, in particular the development of smart nanomaterials, has transformed cancer diagnosis and treatment. The large surface area of nanoparticles is enough to encapsulate many molecules and the ability to functionalize with various biosubstrates such as DNA, RNA, aptamers, and antibodies, which helps in theranostic action. Comparatively, biologically derived nanomaterials perceive advantages over the nanomaterials produced by conventional methods in terms of economy, ease of production, and reduced toxicity. The present review summarizes various techniques in cancer theranostics and emphasizes the applications of smart nanomaterials (such as organic nanoparticles (NPs), inorganic NPs, and carbon-based NPs). We also critically discussed the advantages and challenges impeding their translation in cancer treatment and diagnostic applications. This review concludes that the use of smart nanomaterials could significantly improve cancer theranostics and will facilitate new dimensions for tumor detection and therapy.

“…However, these pollutants have large tendency of enrichment in the environment and even at low concentrations they affect the growth of aquatic organisms, thus affecting human health [ 58 , 59 ]. As per the available statistics, the annual output of PPCPs is ever increasing, with the value exceeding 2 × 10 7 tons in 2016 [ 60 ]. As a consequence of their extensive and frequent use in animal husbandry and human activities, PPCPs have become quasi-persistent pollutants via infiltration of surface water and groundwater during transformation and migration, thus threatening human health due to the intake of polluted drinking water and food.…”

Applications of ionic liquids (ILs) for the modification physicochemical properties of porous materials have been extensively studied with respect to various applications based on the understanding and development of properties of ILs. In this review, IL–graphene composites are discussed and provided a perspective of composites of IL. IL has been used as a medium to improve the dispersibility of graphene, and the resulting composite material shows excellent performance in gas separation and catalysis during environmental treatment. The applications of ILs and IL–functionalized graphene are discussed in detail with the actual environmental issues, and the main challenges and opportunities for possible future applications are summarized.

“…Under this premise, various approaches have emerged to remove this contamination. Among those, carbon materials are becoming a promising substitute for the current lacking technology as they present good stability, tunability, and physio-chemical properties [15][16][17][18][19][20][21][22][23][24] . Moreover, the adsorption method is one of the most appealing approaches due to its simple operation, high efficiency, cost-effectiveness, and low environmental impact [25] .…”

The contamination generated by multiple antibiotics represents a general concern given its impact at the environmental level, mainly affecting the planet’s soil and water and impacting the development of numerous species. Additionally, a new problem has been triggered in terms of the development of antibiotic-resistance genes in various pathogenic microorganisms generating concern for the health sector in terms of the efficiency of antibiotics in the future. These actual problems and concerns demand efforts and actions to remove or eliminate these contaminants. Multiple alternatives to reduce the impact of antibiotics in water have been carried out, such as advanced oxidation, reverse osmosis, and membrane filtration. However, adsorption techniques have presented more favorable and viable results in which carbon-based materials are an efficient tool to remediate the environment that can take advantage of other alternatives due to their characteristics. This review presents different carbon-based absorptive materials such as biochar, carbon nanotubes, activated carbon, and graphene to remove these contaminants, given their characteristics and favorable results. However, process integration, production, and modification continue to be challenging and require more research and experimentation.
