Microfluidic Nano‐Assembly of Red‐Blood‐Cell (RBC) Lipids and Components for Engineering Extracellular Vesicles

Advanced Healthcare Materials, EarlyView.
Engineered red blood cell‐derived extracellular vesicles (eRBCEVs) are synthesized via controlled microfluidic assembly from native RBC lipids, enabling tunable encapsulation of proteins, nucleic acids, nanoparticles, and viral vectors. The platform demonstrates reproducible nanoscale architecture, preserved membrane composition, and functional cargo ...

Rare‐Earth–Functionalized Carbon Dot Hydrogels as Mechanically Robust Antibacterial Wound Dressings

Advanced Healthcare Materials, EarlyView.
The schematic depicts a dynamically cross‐linked PVA hydrogel network in which reversible borate ester bonds and hydrogen‐bonding interactions integrate lanthanum‐doped carbon dots (La‐CDs) and dipotassium glycyrrhizinate (DPG) to form a mechanically robust, multifunctional matrix.

Transition transferases prime bacterial capsule polymerization

Nature Chemical Biology
AbstractCapsules are long-chain carbohydrate polymers that envelop the surfaces of many bacteria, protecting them from host immune responses. Capsule biosynthesis enzymes are potential drug targets and valuable biotechnological tools for generating vaccine antigens. Despite their importance, it remains unknown how structurally variable capsule polymers

A New Method for Staining Bacterial Capsules.

Experimental Biology and Medicine, 1932
A simple method is described by which a capsule-like structure is readily demonstrated about many bacteria. It is selectively stained pink, in contrast to the blue bacterial bodies. Use is made only of stain and fixative. No artificial steps, like preliminary treatment with serum, etc., designed to render the capsule more readily demonstrable, are ...

From Cell‐Derived Vesicles to Hybrid Nanovectors: Biological Membranes as Functional Blueprints for Gene Delivery

Advanced Healthcare Materials, EarlyView.
Biologically derived and hybrid nonviral nanovectors are examined as distinct but convergent design approaches. Integrating synthetic components with biologically functionalized membranes allows efficient interactions with complex cellular environments.

Bacterial Structure with Particular Reference to the Capsule

Experimental Biology and Medicine, 1932
A technic has been described by which capsules can be readily demonstrated not only on “capsulated” organisms but also on certain bacteria and under certain conditions where they are supposed not to exist.1 More extensive studies have confirmed the earlier findings, one of the most significant of which was the observation that R types of pneumococcus ...
