Polymersomes with micellar patches

Journal of Colloid and Interface Science
Hollow block copolymer particles called polymer vesicles (polymersomes) serve as versatile containers for compartmentalization in synthetic biology and drug delivery. Recently, there has been growing interest in using polymersomes as colloidal building blocks for creating higher-order clustered structures.

A micro-incubator for cell and tissue imaging

BioTechniques, 2010
A low-cost micro-incubator for imaging dynamic processes in living cells and tissues has been developed. This micro-incubator provides a tunable environment that can be altered to study responses of cell monolayers for several days as well as relatively ...

Polymersome Crack Film and Its Templating Function in Silica and Gold Deposition

Macromolecular Chemistry and Physics, Volume 227, Issue 13, 15 July 2026.
Polymersome dispersion self‐assembled from PEI‐b‐PPOZ block copolymer in aqueous media can be drop‐cast onto substrates to give cracked films. The cracked film served as an effective catalytic template for the hydrolytic polycondensation of TMOS, producing silica‐coated films that retained the original crack pattern. In addition, gold deposition on the

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.

Mechanical Characterization of Hybrid Vesicles Based on Linear Poly(Dimethylsiloxane-b-Ethylene Oxide) and Poly(Butadiene-b-Ethylene Oxide) Block Copolymers

Sensors, 2016
Poly(dimethylsiloxane-ethylene oxide) (PDMS-PEO) and poly(butadiene-b-ethylene oxide) (PBd-PEO) are two block copolymers which separately form vesicles with disparate membrane permeabilities and fluidities. Thus, hybrid vesicles formed from both PDMS-PEO

Current Perspectives on STING Agonists for Anticancer Drug Development

Chemical Biology &Drug Design, Volume 108, Issue 1, July 2026.
The molecular structures of STING agonists play a decisive role in regulating the STING pathway. Their distinct scaffolds and functional groups orchestrate receptor binding, conformational activation, and the subsequent immune response. ABSTRACT The cyclic GMP‐AMP (cGAS) synthase and stimulator of interferon genes signaling pathway plays a central role

POLIMEROSSOMOS VERSUS LIPOSSOMOS: A EVOLUÇÃO DA “BALA MÁGICA”

Química Nova
Polymeric vesicles known as polymersomes are formed by the self-assemble of amphiphilic block copolymers and have structural organization similar to liposomes.
