“…Previous studies have reported that MNB application can induce a gas supersaturated condition (Wu et al, 2019) which was consistent with the observations seen here. The ultrafine bubbles have a greater surface area per unit volume and can therefore increase the O2 gas transfer rate into the surrounding water (Fan et al, 2021a). In turn, this is expected to enable more efficient activation of the electron hole during photodegradation (Almquist and Biswas, 2001).…”

“…Its chemical structure is shown in Figure S2 [ 43 ]. Cyclodextrin molecules have a hydrophobic inner cavity, while the outer side and the port are hydrophilic [ 44 , 45 , 46 ]. Cyclodextrin inclusion complexes are compounds formed by one or more suitable guest molecules that enter the cavity of cyclodextrin in whole or in part through non-covalent bonds (such as hydrophobic interactions) [ 47 , 48 ].…”

The clinical use of anticancer drugs necessitates new technologies for their safe, sensitive, and selective detection. In this article, lanthanide (Eu3+ and Tb3+)-loaded γ-cyclodextrin nano-aggregates (ECA and TCA) are reported, which sensitively detects the anticancer drug irinotecan by fluorescence intensity changes. Fluorescent lanthanide (Eu3+ and Tb3+) complexes exhibit high fluorescence intensity, narrow and distinct emission bands, long fluorescence lifetime, and insensitivity to photobleaching. However, these lanthanide (Eu3+ and Tb3+) complexes are essentially hydrophobic, toxic, and non-biocompatible. Lanthanide (Eu3+ and Tb3+) complexes were loaded into naturally hydrophilic γ-cyclodextrin to form fluorescent nano-aggregates. The biological nontoxicity and cytocompatibility of ECA and TCA fluorescent nanoparticles were demonstrated by cytotoxicity experiments. The ECA and TCA fluorescence nanosensors can detect irinotecan selectively and sensitively through the change of fluorescence intensity, with detection limits of 6.80 μM and 2.89 μM, respectively. ECA can safely detect irinotecan in the cellular environment, while TCA can detect irinotecan intracellularly and is suitable for cell labeling.

“…[19] It can provide adequate procedures to generate O 2 *À for photocatalytic degradation of APAP and other emerging organic contaminants. [20] Ti-based material could effectively generate O 2 *À through the surface intermolecular electron transfer in the presence of the adsorbed hydrocarbons. [21] Commercial titanium dioxide (P25, Degussa) is widely known for its extremely high photo- catalytic activity under ultraviolet irradiation.…”

Titanate nanotubes (TNTs) were coated with a cyclic oligosaccharide (carboxymethyl-β-cyclodextrin, CM-β-CD) to obtain a photocatalyst (CM-β-CD-TNT) for efficiently activating molecular oxygen and removing the target contaminant. The hydrophobic cavity and the large specific surface area of the photocatalyst provide abundant active sites for activating molecular oxygen. The free radical capture experiment and quenching experiment showed that cyclodextrin could facilitate adsorption and activation of molecular oxygen to produce O 2 *À . Therefore, compared with the pristine TNT, CM-β-CD-TNT accelerated the oxidation efficiency of paracetamol (APAP) by 3.4 times. Moreover, the ring cleavage reaction induced by CM-β-CD-TNT effectively reduced the acute toxicity of wastewater containing APAP. Furthermore, 100% of bisphenol A (BPA), bisphenol S (BPS), phenol, 2,4dichlorophen (2,4-DCP), and carbamazepine (CBZ) were degraded by CM-β-CD-TNT after 2.5 h ultraviolet (UV) light irradiation. This strategy provides a new dimension for the advanced treatment of organic wastewater by organic macrocyclic molecule-modified materials.
