“…The toroid cavity interior of CDS is hydrophobic and contains an isolated microenvironment, which can selectively “encapsulate” compounds of suitable molecular dimensions. Based on this, Yang and co-authors 123 realized the construction of a β-CD covalently-supported TA polymer (Fig. 7(c)).…”

“…Accordingly, the recovery of specific ions from complex wastewater is a crucial topic. Herein, Yang et al 123 tailored an adsorbent by building a CD (β-cyclodextrin) covalently-supported TA polymer nanosponge for the efficient selective recovery of Pb 2+ . Firstly, the TA@CD adsorbent with a mesoporous structure was fabricated via a green and simple chemical crosslinking process (Fig.…”

Cyclodextrin-Based Nanosponges: Overview and Opportunities

et al. 2022

Nanosponges are solid cross-linked polymeric nano-sized porous structures. This broad concept involves, among others, metal organic frameworks and hydrogels. The focus of this manuscript is on cyclodextrin-based nanosponges. Cyclodextrins are cyclic oligomers of glucose derived from starch. The combined external hydrophilicity with the internal hydrophobic surface constitute a unique “microenvironment”, that confers cyclodextrins the peculiar ability to form inclusion host‒guest complexes with many hydrophobic substances. These complexes may impart beneficial modifications of the properties of guest molecules such as solubility enhancement and stabilization of labile guests. These properties complemented with the possibility of using different crosslinkers and high polymeric surface, make these sponges highly suitable for a large range of applications. Despite that, in the last 2 decades, cyclodextrin-based nanosponges have been developed for pharmaceutical and biomedical applications, taking advantage of the nontoxicity of cyclodextrins towards humans. This paper provides a critical and timely compilation of the contributions involving cyclodextrins nanosponges for those areas, but also paves the way for other important applications, including water and soil remediation and catalysis.

BackgroundPesticides are irreplaceable inputs for protecting crops from pests and improving crop yield and quality. Self‐assembly nanotechnology is a promising strategy by which to develop novel nano‐formulations for pesticides. Nano‐formulations improve the effective utilization of pesticides and reduce risks to the environment because of their eco‐friendly preparation, high drug loading, and desirable physicochemical properties. Here, to enhance the utilization efficiency of myclobutanil (MYC) and develop a novel nano‐formulation, carrier‐free co‐assembled nanoparticles (MT NPs) based on MYC and tannic acid (TA) were prepared by noncovalent molecular interactions using a green preparation process without any additives.ResultsThe results showed that the prepared spherical nanoparticles had good stability in neutral and acidic aqueous solutions, low surface tension (40.53 mN m−1), high rainfastness, and good maximum retention values on plant leaves. Release of active ingredients from MT NPs could be regulated by altering the molar ratio of subassemblies in the co‐assembly and the pH of the environment. Antifungal experiments demonstrated that MT NPs had better activities against Alternaria alternata and Fusarium graminearum [half‐maximal effective concentration (EC50) = 6.40 and 77.08 mg/L] compared with free MYC (EC50 = 11.46 and 124.82 mg/L), TA (EC50 = 251.19 and 503.81 mg/L), and an MYC + TA mixture (EC50 = 9.62 and 136.21 mg/L). These results suggested that MYC and TA incorporated in the co‐assembled nanoparticles had a synergistic antifungal activity. The results of a genotoxicity assessment indicated that MT NPs could reduce the genotoxicity of MYC to plant cells.ConclusionCo‐assembled MT NPs with synergistic antifungal activity have outstanding potential for the management of plant diseases. © 2023 Society of Chemical Industry.
