Summary: This report investigates the complexation of azobenzenedyes with cucurbit[7]uril (CB7). The results show that CB7 encapsulates the protonated form of the azobenzene and stabilizes the dye conjugate acid, leading to an increase in pK(a). Molecular modeling suggests that this complex formation is stabilized by ion-dipole interactions, inclusion of the azobenzene ring within the CB7 cavity, and a hydrogen bond between the azo nitrogen and CB7 carbonyls. CB7 complexation not only enhances the stability and hydrophilicity of azobenzene but also offers potential applications in pigment and prodrug development, as well as creating dye displacement assays.

Summary: Using living cells as carriers for target-specific bio-orthogonal catalysis is a cutting-edge approach. However, effectively attaching catalysts to the cells while preserving their interactions with biological systems and maintaining catalytic activity is a challenge. In this study, a layer-by-layer method was developed using a strong noncovalent interaction to create a durable polymer coating on cell surfaces, allowing efficient loading of bio-orthogonal catalysts without impacting cell characteristics or catalyst effectiveness.

Summary: Spectroscopic and computational techniques were used to study the complexation of gabapentin and its lactam form with cucurbit[7]uril in aqueous solution. The results showed that cucurbit[7]uril can form 1:1 complexes with both gabapentin and its lactam form, with a higher preference for the lactam form. The encapsulation of gabapentin within the cavity of cucurbit[7]uril also increased the rate of lactamization, as revealed by NMR spectra.

Summary: Nanoparticle surfactants (NPSs) are powerful tools for stabilizing oil-water interface and constructing all-liquid devices. However, at molecular-scale size, NPSs exhibit dynamic adsorption and liquid-like state due to reduced binding energy. In this study, a supramolecular NPS model called CB[7] surfactant is described, which can form elastic films with excellent mechanical properties at the oil-water interface. The high binding energy of CB[7] surfactant keeps it in a jammed state, transforming the interfacial assemblies from liquid-like to solid-like state and enabling the structuring of liquids. Using CB[7] surfactants as emulsifiers, various emulsions can be prepared, and the assembly/disassembly and jamming/unjamming processes can be controlled, allowing for the reconfiguration of all-liquid constructs.

Summary: This research proposes a method for incorporating thermally activated delayed fluorescence (TADF) dyes with low-cost, heavy metal-free, and long-lived luminescence properties into polymer matrices using a microfluidic droplet-facilitated assembly technique. The resulting composite encoded microparticles (EMPs) are highly monodispersed and efficiently shield TADF dyes from singlet oxygen, preserving TADF emission and increasing the delayed fluorescence lifetime. Additionally, phase separation of polymer blends in the drying droplets allows for spatial separation of TADF dyes with distinct colors, eliminating optical signal interference and generating multiple fluorescence colors. Furthermore, the resulting EMPs show good biocompatibility and allow cells to adhere and grow on the surface, making them promising for biolabeling applications.

Summary: The integration of liposomes into hydrogels can be achieved through direct soaking, providing advantages such as easy formulation, enhanced drug stability, and controlled release kinetics. However, the development of matching porous structures within hydrogels and achieving appropriate affinity with liposomes has been challenging. A new method is proposed for synthesizing macroporous hydrogels, which involves the use of thiolated hyaluronic acid and hyperbranched polyethylene glycol macromonomers in combination with a freezing-induced secondary crosslinking process. This approach allows the formation of macropores that can be locked during freezing and enables easy modification of the hydrogels for liposome association.

Summary: This study compared the therapeutic effects of exosomes derived from different sources of stem cells in osteoarthritis (OA) treatment. The results showed that exosomes derived from infrapatellar fat pad (IPFP) stem cells had a significantly stronger inhibitory effect on the degradation of cartilage extracellular matrix (ECM) compared to those derived from subcutaneous adipose tissue (ScAT) stem cells. Furthermore, microRNA sequencing revealed differences in microRNA expression between the two types of exosomes, and overexpression of a specific microRNA in ScAT-derived exosomes demonstrated efficacy in inhibiting the expression of ADAMTS4, promoting ECM repair in OA. Additionally, a hyaluronan-based hydrogel microparticles (HMPs) encapsulating exosomes were fabricated using microfluidic technology, and their injectability, sustained release, and long-term therapeutic effects on OA were validated.
