Coarse-Grained Molecular Dynamics Modelling of a Magnetic Polymersome

Nanomaterials, 2018
A coarse-grained molecular dynamics framework is proposed to investigate the equilibrium structure and quasi-static deformational response of a magnetic polymersome, a hollow object whose magnetoactive part is its shell (membrane).

Phase Separation of Nucleic Acids: Mechanisms, Properties, and Applications

Angewandte Chemie International Edition, Volume 65, Issue 11, 9 March 2026.
Recent discoveries have shown that single‐stranded long‐chain nucleic acids can undergo temperature‐induced phase separation, enabling formation of micrometer‐sized condensates. This Minireview discusses the current mechanistic understanding of this phenomenon, highlights strategies for controlling the physical and chemical properties of these ...

Programmable Enzymatic Reaction Network in Artificial Cell‐Like Polymersomes

Advanced Science
The ability to precisely control in vitro enzymatic reactions in synthetic cells plays a crucial role in the bottom‐up design of artificial cell models that can recapitulate the key cellular features and functions such as metabolism. However, integration

Click on Click: Click-Flavone Glycosides Encapsulated in Click-Functionalised Polymersomes for Glioblastoma Therapy

Pharmaceutics
In this study, three new 3,7-dihydroxyflavone (1) derivatives with different sugars were designed and synthesised by click chemistry. Click chemistry requires the previously modification of building blocks with azide and alkyne groups and therefore, the ...

Polyferrocene‐Based Cubosomes: Conversion to Magnetic Mesoporous Microparticles, Supramolecular Modification, and Oxidation Response

Advanced Functional Materials, Volume 36, Issue 19, 5 March 2026.
Polyferrocene block copolymers are synthesized and assembled into micron‐sized polymer cubosomes with double diamond lattice and pore diameter of ≈30 nm. The ferrocene functionality is retained within the polymer cubosome wall as demonstrated on supramolecular modification, and oxidative disassembly.

Organic Afterglow Vesicles

Advanced Science, Volume 13, Issue 16, 18 March 2026.
This work constructs organic afterglow vesicles through polymerization‐induced self‐assembly (PISA), integrating thermally activated delayed fluorescence (TADF) type organic afterglow emitters into block copolymer nanostructures. The resulting vesicles exhibited significant room‐temperature afterglow, with an emission lifetime exceeding 200 ...

Quercetin and Its Nano‐Based Formulations Against Skin Cancer: A Narrative Review

Health Science Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Background Skin cancer is one of the most prevalent malignancies worldwide, characterized by the abnormal growth of skin cells and significant clinical challenges. Conventional treatments—including surgery, chemotherapy, and radiotherapy—often suffer from limitations such as adverse side effects, tumor resistance, and inadequate efficacy.

Enzymatically triggered rupture of polymersomes [PDF]

Soft Matter, 2016
Polymersomes are robust vesicles made from di-block co-polymers. We have engineered a two step enzymatic cascade to trigger the release of contents from polymersomes, in which extravesicular glucose oxidase makes hydrogen peroxide, when then penetrates the membrane and is converted by entrapped catalase to oxygen, leading to vesicle failure.

Buoyancy‐Driven Flotation and Magnetotaxis of Vesicle‐Based Prototissue Fibers Induced by Oxygen Bubbles under Enzymatic Reactions

ChemSystemsChem, Volume 8, Issue 2, March 2026.
We demonstrate new strategies to induce motility of vesicle‐based prototissue fibers by generating oxygen bubbles under an enzymatic reaction. The prototissue fibers exhibited flotation due to the buoyancy of oxygen bubbles and magnetotaxis due to the paramagnetic property of oxygen.
