Light‐Activated Communication Between Synthetic and Living Cells via Photoresponsive Membranes

ChemBioChem, Volume 27, Issue 14, 29 July 2026.
Light‐triggered membrane rupture of SCs enables controlled release of adenosine triphosphate (ATP) and histamine, which activate purinergic and histaminergic signaling in HeLa cells, leading to intracellular Ca2+ mobilization. This biomimetic communication platform provides a simple strategy for engineering remotely controlled chemical signaling ...

Auf dem Weg zu chromoselektiven Transformationen in biologischen Systemen: Perspektiven und Herausforderungen

Angewandte Chemie, Volume 138, Issue 31, 27 July 2026.
Die Kontrolle biologischer Systeme mit organischen Chromophoren hat sich zu einer vielversprechenden Strategie entwickelt und findet Anwendung von der chemischen Biologie bis hin zur Medizin. Die Komplexität von In‐vivo‐Systemen lässt sich jedoch nicht mit nur einer einzigen Lichtwellenlänge adäquat abbilden.

Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges

Angewandte Chemie International Edition, Volume 65, Issue 31, 27 July 2026.
Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.

Polymerization-Induced Polymersome Fusion [PDF]

Journal of the American Chemical Society, 2019
The dynamic interactions of membranes, particularly their fusion and fission, are critical for the transmission of chemical information between cells. Fusion is primarily driven by membrane tension built up through membrane deformation. For artificial polymersomes, fusion is commonly induced via the external application of a force field. Herein, fusion-

The simultaneous role of porphyrins’ H- and J- aggregates and host–guest chemistry on the fabrication of reversible Dextran-PMMA polymersome

Scientific Reports, 2021
Aggregation-induced quenching of porphyrin molecules as photosensitizer significantly reduces the quantum yield of the singlet oxygen generation, and it is able to decrease the efficacy of photodynamic therapy.

Beyond Molecular Determinism: State‐Convergent Polymerization as a Functional Design Principle Under Chemical Complexity

Advanced Science, Volume 13, Issue 38, 9 July 2026.
This work introduces state‐convergent polymerization (SCP), a polymerization framework in which chemically diverse reaction pathways converge toward a reproducible functional polymeric state rather than a defined molecular structure. Using melanin and polydopamine as exemplars, SCP explains how robust polymer functions emerge under chemical and ...

PEG Alternatives in Liposomal Nanocarriers: Physicochemical Characteristics and Sustainable Process Strategies

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 4, July/August 2026.
ABSTRACT The global trend toward sustainable and intensified bioprocesses is driving innovation in the design and scalable synthesis of liposomal nanocarriers, a cornerstone of modern drug delivery. For decades, these nanosystems have relied exclusively on polyethylene glycol (PEG) for their sustained circulation in vivo, but they are currently ...
