Summary: Nanogels that combine the properties of hydrogels and nanocarrier systems are effective drug delivery systems, especially for cutaneous applications. Cyclodextrins can enhance the loading ability of nanogels for poorly soluble drugs and promote sustained drug release. The use of a soluble beta-cyclodextrin/epichlorohydrin polymer (EPI beta CD) without toxic crosslinkers can improve drug delivery efficiency for ibuprofen through enhanced solubility and sustained release.

Summary: Extracellular vesicles play a crucial role in intercellular communication and cell physiology, but quantitative knowledge on their signaling mechanisms is lacking, hampering their therapeutic applications. By using a synthetic approach, researchers have shown that synthetic EVs have functionalities similar to natural EVs and can be used for therapeutic purposes in wound healing and neovascularization. Transcriptome profiling has enabled a systematic decoding of synergistic effects between individual EV constituents, leading to a better understanding of EV signaling.

Summary: Wedge-shaped dendrons based on benzenesulfonic acid can form different liquid crystal mesophases, such as ordered and disordered columnar hexagonal ones. The size and nature of focal groups as well as the length of aliphatic tails are important factors affecting the phase behavior of these materials. The study found that certain dendrons can form a 2D columnar ordered hexagonal mesophase with three annuli: a central channel, virtually hollow channel, and rigid aromatic part enveloped by an aliphatic matrix. The material shows promise for creating temperature-controlled ion-selective membranes.

Summary: This study demonstrates the reversible formation of hydrogels through hydrophobic interaction using poly(N-alkyl-N-vinylacetamide)s. The polymers with different lengths of alkyl chains can dissolve in ethanol and form thin films. When immersed in water, they swell and form biocompatible hydrogels. The hydrophobic association varies with the length of the alkyl substituents, with shorter chains leading to flowable hydrogels that segregate from excess water and longer chains yielding hydrogels with mechanical properties similar to permanently cross-linked hydrogels.
