Summary: Near-infrared fluorophores are widely used in tumor imaging due to their superior resolution, sensitivity, penetration depth, and low auto-fluorescence. However, the efficacy of these fluorophores in tumor imaging is often hindered by background signals and delivery efficiency. The self-quenched liposomal probes DiR-LP-C and DiR-LP-B have been developed as tumor-specific imaging probes with a cellular on/off system, showing potential for tumor imaging and phototherapy.

Summary: The study demonstrates that the release ability of sphingomyelin liposomes in liposomal delivery is affected by treatment with sphingomyelinase enzyme, which can make the liposomes leakier and sensitive to cellular stress. Under radiation-induced stress, the targeting ability of liposomes is enhanced, with a higher concentration of released fluorescent markers found at cancer sites.

Summary: A porous nanocomposite of layered double hydroxide (LDH) nanosheets and chitosan biopolymer was developed for easy uptake and selective release of cosmetic liposome capsules. The nanocomposite exhibited a high BET surface area and porous structure, allowing for controlled release of large liposome particles depending on solution pH and anions. The polymer network effectively blocked liposome release and the nanocomposites could be successfully reused after washing with ethanol.

Summary: Quantum dots (QDs) are nanoparticles with excellent optical properties, suitable for various biomedical applications. However, their potential use in clinical settings is limited by their toxicity. Current research mainly focuses on QDs' induction of cell death through ROS and apoptosis, overlooking other aspects of QDs' toxicity. Therefore, our study investigates the direct interaction between QDs and proteins to explore another mechanism by which QDs negatively impact cellular processes.

Summary: High-efficiency chemiluminescence (CL) resonance energy transfer (CRET) can be achieved by shortening the donor-acceptor distance and/or improving the luminescence efficiency of CRET acceptors. The AIE-active fluorophore adsorbed on the surface of LDHs exhibited high-efficiency luminescence, while LDHs can further adsorb ONOO-. The proposed CL system successfully detected NaNO2 in a concentration range from 1.0 to 100 mu M.

Summary: Graphene-based materials are increasingly utilized in novel nanomedicine technologies due to their large contact and loading surfaces as well as high sensitivities to chemical changes. The study on biomolecule-monolayer graphene-kidney tissue hybrid structures revealed a double-sided graphene-enhanced Raman scattering effect and efficient autofluorescence quenching caused by graphene on kidney tissue emissions. These phenomena can be explained by molecular structure and energy level alignment, leading to effective charge transfer.

Summary: Flavonoids, a class of widely existing polyphenols in food and medicine, have various pharmacological effects such as anti-oxidative, anticancer, and anti-inflammatory effects. However, their low bioavailability limits their clinical application, which is related to their intestinal absorption and metabolism. This review aims to establish the structural requirements of flavonoids for notable anticancer, anti-inflammatory, and antioxidant effects, and discuss the use of nanotechnology for safe delivery of flavonoids in food matrices.

Summary: In this study, protein-polyphenol-polysaccharide ternary complexes were prepared, and the influence of different factors on the complex formation process was investigated. The results showed that the ternary complex exhibited smaller particle size and better emulsion stability when the mass concentration ratio of gelatin to high methoxyl pectin was 9:1, EGCG addition was 0.05%, pH value was 3.0, and ionic strength was 10 mmol L-1. The addition of EGCG promoted the dispersion of the ternary complex and reduced agglomeration. Fluorescence intensity differences indicated interactions between EGCG and gelatin, leading to changes in the protein spatial conformation. Fourier transform infrared spectroscopic analysis revealed that hydrogen bond interaction was the primary non-covalent interaction between EGCG and the gelatin-high methoxyl pectin binary complex.

Summary: This study aims to investigate the effects of casein/cyanidin-3-O-glucoside nanoparticles (CsC3G) on gut microbiota disorders induced by a high-fat diet. In C57BL/6 mice fed a high-fat diet, Cs-C3G improved fat accumulation and liver oxidative stress. Cs-C3G, as a dietary supplement, restored the abundance and diversity of gut microbiota, decreased the ratio of Firmicutes to Bacteroidetes, increased beneficial microorganisms, and reduced opportunistic pathogenic bacteria. Overall, Cs-C3G regulated the disturbance of gut microbiota, preventing HFD-induced obesity and liver damage.

Summary: Bacillus albus YUN5, isolated from doenjang, showed high degradation capabilities for aflatoxin B1 (AFB1) and aflatoxin G1 (AFG1). The cell-free supernatant (CFS) of B. albus YUN5 exhibited the highest degradation efficiency, while negligible degradation was observed in other fractions. Optimal degradation conditions were determined to be 55℃, pH 7-10, and salt concentration of 0-20%. Liquid chromatography-mass spectroscopy analysis revealed the target sites of degradation. The application of B. albus YUN5 in doenjang fermentation showed better reduction of AFB1 and AFG1 compared to without B. albus YUN5.

Summary: Flavonoid compounds play a significant role in promoting health, but current research focuses mainly on their individual functions rather than their complex relationships in food. The gut microbiome is also important in the metabolism of flavonoids, but more progress is needed in this area. This review examines the interactions between flavonoids and food matrices, and their effects on the nutritional properties and bioavailability of flavonoid compounds. The health effects of the interaction between flavonoids and the gut microbiome are also discussed.
