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

Polymersomes in “Gelly” Polymersomes: Toward Structural Cell Mimicry [PDF]
Langmuir, 2011 We demonstrate here the formation of compartmentalized polymersomes with an internal "gelly" cavity using an original and versatile process. Nanosize polymersomes of poly(trimethylene carbonate)-b-poly(L-glutamic acid) (PTMC-b-PGA), formed by a solvent displacement method are encapsulated with a rough "cytoplasm mimic" in giant polymersomes of poly ...

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 ...

A new approach to high resolution, high contrast electron microscopy of macromolecular block copolymer assemblies [PDF]
, 2013 Determining the structure of macromolecular samples is vital for understanding and adapting their function. Transmission electron microscopy (TEM) is widely used to achieve this, but, owing to the weak electron scattering cross-section of carbon, TEM ...

A novel diblock copolymer of (monomethoxy poly [ethylene glycol]-oleate) with a small hydrophobic fraction to make stable micelles/polymersomes for curcumin delivery to cancer cells [PDF]
, 2014 Curcumin is a potent natural anticancer agent, but its effectiveness is limited by properties such as very low solubility, high rate of degradation, and low rate of absorption of its hydrophobic molecules in vivo.
