Cancer is a complex disease associated with a combination of abnormal physiological process and exhibiting dysfunctions in multiple systems. To provide effective treatment and diagnosis for cancer, current treatment strategies simultaneously focus on various tumor targets. Based on the rapid development of nanotechnology, nanocarriers have been shown to exhibit excellent potential for cancer therapy. Compared with nanoparticles with single functions, multifunctional nanoparticles are believed to be more aggressive and potent in the context of tumor targeting. However, the development of multifunctional nanoparticles is not simply an upgraded version of the original function, but involves a sophisticated system with a proper backbone, optimized modification sites, simple preparation method, and efficient function integration. Despite this, many well‐designed multifunctional nanoparticles with promising therapeutic potential have emerged recently. Here, to give a detailed understanding and analyzation of the currently developed multifunctional nanoparticles, their platform structures with organic or inorganic backbones were systemically generalized. We emphasized on the functionalization and modification strategies, which provide additional functions to the nanoparticle. We also discussed the application combination strategies that were involved in the development of nanoformulations with functional crosstalk. This review thus provides an overview of the construction strategies and application advances of multifunctional nanoparticles.

Heterogeneous photocatalysts have garnered extensive attention as a sustainable way for environmental remediation and energy storage process. Water splitting, solar energy conversion, and pollutant degradation are examples of nowadays applications where semiconductor-based photocatalysts represent a potentially disruptive technology. The exploitation of solar radiation for photocatalysis could generate a strong impact by decreasing the energy demand and simultaneously mitigating the impact of anthropogenic pollutants. However, most of the actual photocatalysts work only on energy radiation in the Near-UV region (<400 nm), and the studies and development of new photocatalysts with high efficiency in the visible range of the spectrum are required. In this regard, hybrid organic/inorganic photocatalysts have emerged as highly potential materials to drastically improve visible photocatalytic efficiency. In this review, we will analyze the state-of-art and the developments of hybrid photocatalysts for energy storage and energy conversion process as well as their application in pollutant degradation and water treatments.

Bismuth(III)-based materials are uniquely suited for in situ subsurface remedy applications, as they offer many beneficial properties, including high affinity for multiple contaminants, low human and environmental toxicity, low cost, and synthetic availability. This review summarizes the current research trends in targeted development of bismuth materials potentially useful for subsurface remedy applications, with an emphasis on recent advances in understanding of relevant structure–property relationships. While various bismuth mineral phases can provide frameworks for contaminant sequestration, layered crystalline arrangements are particularly promising because of their electronic and spatial flexibility and their ability to accommodate a wide range of negatively charged species. This translates into a high uptake capacity for several recalcitrant colocated contaminants found at legacy nuclear processing sites, including technetium-99, iodine-129, hexavalent chromium (chromate), and uranium, and offers the potential for both in situ and ex situ remediation applications. Layered bismuth minerals are found in nature, and knowledge of their structure informs the targeted design and cost-effective synthesis of the structurally preorganized materials from readily available bismuth sources for remedial applications in soil and groundwater. This comprehensive review highlights the structure, synthesis, and environmental chemistry of Bi-based materials, including the interaction between Bi-based materials and key environmental contaminants, to explore their potential use for remediation. Bismuth oxyhydroxides, containing clusters of [Bi6O4(OH)4]6+ and [Bi6O5(OH)3]5+ surrounded by easily exchangeable anions such as nitrate, are versatile and show the greatest potential for environmental remediation applications. Because of their flexible structural arrangement, they have been shown to sequester electronically and sterically different anionic species, including chromate, pertechnetate, iodate, and uranyl carbonate, even when they are present as comingled contaminants in groundwater and pore water containing other competing anions (e.g., nitrate and carbonate) and in contact with subsurface sediments.
