Summary: In this study, a quartet photosensitizer Cy-DENT with high singlet oxygen quantum yield was reported, achieved through a radical enhanced inter-system crossing process. By introducing a TEMPO radical, over 20-fold enhancement of singlet oxygen quantum yield compared to Cy-DEN could be achieved under near infrared light irradiation. The electron-donating ability of the terminal substituent group can effectively control the production of singlet oxygen.

Summary: The emergence of antimicrobial resistance has made the development of photodynamic therapy (PDT) related applications essential, since microorganisms cannot develop resistance to this method. This study focuses on the synthesis, characterization, and evaluation of the utility of palladium porphyrins and their chitosan inclusion complexes as photosensitizer dye in photodynamic antimicrobial therapy (PACT). The photophysical-chemical studies showed that the immobilization of the porphyrins into the chitosan influenced their properties. Furthermore, the PACT activity of cationic porphyrin and its chitosan immobilization form were found to be effective in decreasing the number of viable cells up to 100% in vitro.

Summary: The study found that introducing electron-withdrawing fluorine atoms into the PC moiety can significantly enhance singlet oxygen generation and promote intersystem crossing. Cyclic voltammetry experiments revealed a linear relationship between quenching rate constants and oxidation potentials, indicating that the substituent effect is a key factor governing the efficiency of photosensitizers in generating singlet oxygen.

Summary: Symmetry of layered dipeptide crystals can be broken by utilizing CO2, which induces adjacent monomolecular layers to stack in the same direction. CO2 covers the interlayer interaction sites, forcing the dipeptides to adsorb asymmetrically. The dipeptide crystals exhibit enhanced piezoelectricity and the piezoelectric voltage generated from dipeptide-based generators is increased by more than 500% after symmetry breaking. This work provides a potential route to engineer structures and properties of layered materials, and offers insights into the control of non-covalent interactions.

Summary: The development of peptide-based supramolecular materials with hierarchical morphology and tunable guest loading shows great potential as a drug carrier due to their biocompatibility and biodegradability. In this study, a facile Schiff base nanoarchitectonic was reported for the supramolecular assembly of diphenylalanine (FF) metastable gel. The competitive assembly between FF-H2O and FF-GA oligomer resulted in the formation of FF nanoparticles and hierarchical beaded nanofibers. These assembled particles can easily load various guest molecules and release them under weak alkaline conditions, demonstrating their potential application as drug carriers.

Summary: A strategy of matched spectral and temporal light management is developed to improve photosynthetic efficiency by co-assembling natural thylakoid membrane (TM) with artificial long afterglow particle (LAP). LAP with excellent stability and biocompatibility is optically-matched with the absorption of TM, serving as an additional light source for photosynthesis. Enhanced photosynthesis is achieved after co-assembly, with boosted electron transfer, oxygen yield, and ATP production due to down-conversion fluorescence emission from LAP. This proof-of-concept work opens a new route to augment the photosynthetic efficiency of green plants by utilizing precise light-managed materials.

Summary: This study reports, for the first time, that Celastrol can self-assemble into size-controllable nanoparticles via the anti-solvent method using different solvents or varying Celastrol concentrations. In vitro experiments showed that the prepared nanoparticles can effectively kill MCF-7 cells. Furthermore, the nanoparticles can accumulate efficiently in tumors after intravenous injection. Administration of a lethal dosage of Celastrol resulted in significant tumor suppression with maintained activity in mice. These findings suggest that the anti-solvent method holds promise for fabricating Celastrol nano-drugs with controlled size and reduced systemic toxicity for clinical cancer treatment.

Summary: We demonstrate the realization of photozyme-catalyzed oxidative phosphorylation through the assembly of ATP synthase-reconstituted proteoliposome coatings on microcapsules. This is achieved through layer-by-layer deposition of semiconducting graphitic carbon nitride (g-C3N4) nanosheets and polyelectrolytes. The encapsulated g-C3N4 nanosheets act as the photozyme, accelerating the oxidation of glucose to yield protons under light illumination, establishing an outward transmembrane proton gradient to drive ATP synthesis. This artificial design enables higher energy conversion efficiency compared to conventional oxidative phosphorylation systems.

Summary: Controlling the morphology of supramolecular hydrogels is crucial in tuning their mechanical properties. This study investigates the evolution of fibrillar networks in hydrogels by modulating droplets formed via liquid-liquid phase separation. The size and amount of droplets, as well as the structural evolution and network development, can be finely tuned by varying the thermal history. The findings provide insights into the role of phase-separated droplets in self-assembling networks and contribute to the engineering of supramolecular hydrogels with adjustable mechanical properties.
