Summary: This work presents a general and efficient method to synthesize pH-responsive near-infrared (NIR) emitting gold nanoclusters by introducing aliphatic tertiary amine (TA) groups as ligands. The pH-responsive NIR emission is achieved through the protonation and deprotonation of TA groups, which induce electronic structure changes. The pH-responsive gold nanoclusters can serve as specific and sensitive probes for lysosomes in cells, offering non-invasive emissions without interference from intracellular autofluorescence.

Summary: This research develops a nanomedicine based on polycation, which targets visceral fat selectively, preventing obesity and alleviating metabolic dysfunctions. By modulating nutrient-sensing signalling pathways, the polycation uncouples lipid synthesis and storage from adipocyte development, resulting in adipocytes with normal functions but deficient in hypertrophic growth. The study suggests the potential of cationic nanomaterials in treating metabolic diseases.

Summary: In this study, a universal strategy for the integration of inorganic perovskite quantum dots (PQDs) and polymers was reported. By designing and synthesizing photopolymerizable CsPbX3 (X = Cl, Br, I) QD inks with enhanced stability, high-resolution, multicolored fluorescent patterns were achieved on surface-silanized polymers through high-throughput photolithography and inkjet printing. The covalent bonding at the organic-inorganic interface ensured the patterns could be freely stretched and folded without delamination. Furthermore, a light-driven self-deployable information display was demonstrated by integrating photopolymerizable PQDs with a 4D-printed shape-morphing liquid crystal elastomer. This research expands the emerging applications of perovskite-polymer materials with unprecedented functionalities.

Summary: Polyols and polyacrylates are widely used in polymer synthesis and can be used as monomers, initiators, or building blocks. Finding bio-based/renewable sources for these compounds is crucial due to the increasing need to reduce dependency on fossil fuels. By functionalizing the alkene moieties of common terpenes through oxidation, the toolbox of bio-based diols and triols is expanded. These polyols can be easily converted into terpene-derived diacrylates under mild conditions. As demonstrated, these monomers can be used in aza-Michael polymerizations to form new (bio)degradable poly-beta-amino esters.

Summary: The limited efficacy of standard glioblastoma (GBM) treatments is attributed to the highly immunosuppressive characteristics of the tumor microenvironment, interpatient tumor heterogeneity, and physical barriers like the blood brain barrier. In this study, a new local therapy combining doxorubicin (DOX) and CpG was proposed, which exhibited synergistic effects in eradicating GBM. Bioresponsive hyaluronic acid (HA)-drug conjugates were designed for in situ chemoimmunotherapy, with CpG and DOX being conjugated separately to HA. The combined delivery of HA-DOX + HA-CpG showed promising results in a GBM animal model, inducing immune responses, reducing tumor-associated macrophage infiltration, and resulting in long-term survival in a significant percentage of treated animals.

Summary: This study compared the membrane association, cellular uptake, and delivery capacity of all-l and all-d enantiomers of penetratin in different cell models and cargos. The results showed that d-PEN had tighter membrane binding and was superior in delivering hydrophilic peptide cargoes across the Caco-2 epithelium compared to l-PEN. However, there was no enhanced delivery of the hydrophobic cyclosporin, and both enantiomers had similar intracellular insulin uptake.

Summary: The surface density of targeting agents affects the cell interaction, mechanism of cell entry, and intracellular fate of surface decorated nanoparticles. Increasing folic acid density on folate-targeted gold nanoparticles has been shown to enhance their internalization and trafficking to lysosomes in folate receptor overexpressing cells. Higher folic acid density induces more efficient particle internalization and predominantly internalizes the particles by a clathrin-independent process.

Summary: This study reports the biological properties of D-Q53 CecB, which is an all-D enantiomer of the silkworm natural peptide Q53 CecB. Compared to the L-variant, D-Q53 CecB shows enhanced bactericidal activity against P. aeruginosa planktonic bacteria and resistance to in vitro degradation by humans and P. aeruginosa elastases. It is thermostable and maintains its antimicrobial activity at high salt concentrations and in the presence of divalent cations or fetal-bovine serum. In addition, D-Q53 CecB shows cytotoxic phenomena at higher concentrations against different types of human cells. It is also effective in inhibiting and degrading biofilms, making it a favorable candidate for anti-Pseudomonas therapy.
