Polymersomes Eradicating Intracellular Bacteria [PDF]
ACS Nano, 2020 Mononuclear phagocytes such as monocytes, tissue-specific macrophages, and dendritic cells are primary actors in both innate and adaptive immunity. These professional phagocytes can be parasitized by intracellular bacteria, turning them from housekeepers to hiding places and favoring chronic and/or disseminated infection.

Journal of the American Chemical Society, 2023 The contents of biological cells are retained within compartments formed of phospholipid membranes. The movement of material within and between cells is often mediated by the fusion of phospholipid membranes, which allows mixing of contents or excretion of material into the surrounding environment.

DNA-tethered Polymersome Clusters as Nanotheranostic Platform
CHIMIA, 2021 Nanotheranostics combine the use of nanomaterials and biologically active compounds to achieve diagnosis and treatment at the same time. To date, severe limitations compromise the use of nanotheranostic systems as potent nanomaterials are often ...

Adaptive Polymersome Nanoreactors [PDF]
ChemNanoMat, 2019 AbstractAdaptive polymersome systems have gained much interest in a wide variety of research fields, ranging from cell mimics to nanomedicine, because of their high stability, tunable shape and size. Furthermore, polymersomes can be effectively transformed into nanoreactors via the incorporation of catalytic species. By employing polymersomes which are

Chemical Communications, 2007 Polymersomes, composed of amphiphilic polystyrene-block-poly(acrylic acid) (PS-b-PAA), with the periphery being covered with azide groups, were used for further functionalization using "click" chemistry.

Paramagnetic Porous Polymersomes [PDF]
Langmuir, 2008 The ability of chelated Gd to serve as an effective magnetic resonance (MR) contrast agent largely depends on fast exchange rates between the Gd-bound water molecules and the surrounding bulk water. Because water diffuses slowly across lipid bilayers, liposomes with encapsulated chelated Gd have not been widely adopted as MR contrast agents.

Engineering Polymersome Protocells [PDF]
The Journal of Physical Chemistry Letters, 2011 The field of biomimicry is embracing the construction of complex assemblies that imitate both biological structure and function. Advancements in the design of these mimetics have generated a growing vision for creating an artificial or proto- cell. Polymersomes are vesicles that can be made from synthetic, biological or hybrid polymers and can be used ...

Cascade Reactions in Multicompartmentalized Polymersomes [PDF]
Angewandte Chemie, 2013 AbstractEnzyme‐filled polystyrene‐b‐poly(3‐(isocyano‐L‐alanyl‐aminoethyl)thiophene) (PS‐b‐PIAT) nanoreactors are encapsulated together with free enzymes and substrates in a larger polybutadiene‐b‐poly(ethylene oxide) (PB‐b‐PEO) polymersome, forming a multicompartmentalized structure, which shows structural resemblance to the cell and its organelles.
