Summary: The combined method of photodynamic therapy and chemotherapy for treating malignant neoplasms shows great promise. This study investigates the properties of a supramolecular system based on TSPP and LaSurf in an aqueous medium. The complexes can assemble into nanostructures capable of binding anticancer drugs and their stability and drug binding ability can be controlled by adjusting the molar ratio and concentration of the components.

Summary: Imposing chirality to supramolecular architectures is crucial for understanding and utilizing chiral nanomaterials. The self-assembly of amphiphilic chiral copolymers into helical supramolecular rods is achieved through intrachain stacking of chiral units along the main chain. The reversible supramolecular self-assembly retains sublevel chirality even when the helical appearance is destroyed.

Summary: Due to simple synthetic strategies, randomly functionalized amphiphilic polymers have become highly researched. Recent studies have shown that these polymers can self-assemble into various nanostructures, similar to amphiphilic block copolymers. The study explored the self-assembly behavior of randomly functionalized hyperbranched polymers and their linear analogues in solution and at the liquid crystal-water interfaces. Regardless of their architecture, the designed amphiphiles formed spherical nanoaggregates in solution and influenced the ordering transitions of liquid crystal molecules at the liquid crystal-water interface. However, the linear analogues required 10 times less amphiphiles compared to the hyperbranched polymers to achieve the same ordering transition of liquid crystal molecules. Additionally, only the linear analogues responded to biorecognition events, which can be attributed to both of the aforementioned differences.

Summary: The study explores the induction of multistep phase transitions using cationic amphiphiles in molecular crystals, with insights into the phase transitions mechanism revealed through H-1 NMR and fluorescence anisotropy measurements. The findings suggest that multiple pathway-dependent phase transitions of supramolecular self-assemblies can offer a methodology for the development of new stimuli-responsive materials.

Summary: This study presents a novel method for self-assembly using chitin nanocrystals in capillaries. The fixed-boundary evaporation-induced self-assembly (FB-EISA) modality is employed, where a fixed air-liquid interface at the end of capillaries serves as the evaporation interface and initial deposition site of chitin nanocrystals. Through successive evaporation, continuous birefringent structures with a density gradient are generated, leading to the formation of cylindrical tubes.

Summary: Combining metal complexes with amphiphilic molecules can result in diverse functional self-assembled nanostructures. Metal complexes that undergo spin transitions are good candidates to trigger structural conversion of such assemblies due to their response to external stimuli. In this study, we investigated the structural conversion of a supramolecular assembly containing a [Co2Fe2] complex through thermally induced electron transfer-coupled spin transition (ETCST). In the presence of an amphiphilic anion, the [Co2Fe2] complex formed reverse vesicles in solution and exhibited thermal ETCST. Conversely, thermal ETCST in the presence of a bridging hydrogen-bond donor led to structural conversion from reverse vesicles to entangled one-dimensional chains through hydrogen bond formation.

Summary: The study demonstrates the photodynamic activity of phthalocyanine-assembled nanoparticles against bacterial strains. Two chiral Zn(II)Pcs were studied, showing efficient photo-inactivation capacity against both Gram-positive and Gram-negative bacteria. The self-assembled nanostructures of PS-1 were found to be more effective at killing both types of strain compared to PS-2.

Summary: This study investigates the self-assembly of polymer-tethered metal nanoparticle building blocks using an emulsion interface self-assembly strategy. It successfully obtains hollow colloidosomes with a highly ordered hexagonal arrangement of metal nanoparticle building blocks. The interparticle distance within the colloidosomes can be tuned by adjusting the molecular weight of the polymeric ligands. Furthermore, it shows that sheet-like superlattices can be formed by increasing the volume fraction of the internal hexadecane phase. The prepared colloidosomes have potential applications in surface enhanced Raman scattering and photothermal therapy.

Summary: Two new classes of near-infrared molecular probes were developed that exhibit turn on fluorescence when cleaved by the nitroreductase enzyme. These probes have structures that enhance fluorescence brightness and provide better performance when excited by 808 nm light. One of the probes showed higher activity and less self-aggregation when applied in vivo, making it the preferred choice.

Summary: In this study, we introduce carbon monoxide-photoreleasable compounds (photoCORMs) comprised of heptamethine cyanine and flavonol chromophores, which are activated by near-infrared light. These compounds exhibit excellent CO-release yields and uncaging cross sections in aqueous solutions, and their water solubility is enhanced through polar substituents or a host-guest approach using cucurbit[7]uril. Additionally, these hybrids demonstrate outstanding biocompatibility as well as diverse, structure-dependent cell penetrability and internalization.

Summary: Sensitization of lanthanide-doped upconversion nanocrystals (UCNCs) using organic dyes with broad and intense optical absorption is an interesting approach for enhancing their upconversion luminescence. The study showed that specific dyes like Cy 754 can greatly enhance the upconversion efficiency of UCNCs, while the triplet states of dyes play a significant role in the sensitization process.
