Controlling the Morphology of Poly(ethylene glycol)-b-poly(lactide) Self-Assemblies in Solution: Interplay of Homopolymer Additives and Kinetic Traps.

This study investigates the effects of homopolymer additives and kinetic traps on the self-assembly of poly(ethylene glycol)-b-poly(lactide) (PEG-PLA) block copolymer (BCP) nanostructures in aqueous environments. By using non-adsorbing PEG homopolymers to kinetically trap PEG-PLA nanostructures, we demonstrate that varying the concentration and molecular weight of the added PEG induces a reversible micelle-to-vesicle transition. This transition is primarily driven by changes in the molecular geometry of the PEG-PLA BCPs due to excluded volume screening effects.

Covalent organic nanotubes offer enhanced stability, robustness, and functionality, compared to their noncovalent counterparts. This study explores constructing polydiacetylene (PDA) nanotubes using a two-step process: self-assembly via noncovalent interactions followed by UV-induced polymerization of a diacetylene template. A promising building block consisting of a hydrogen-bonding headgroup, barbituric acid, linked to a linear diacetylene chain was prepared.

Despite significant advances in diverse cancer treatment methods, chemotherapy remains the primary approach, and the development of chemoresistance is still a persistent problem during treatment. Here, we developed a derivative of the natural product mangiferin as a carrier for delivering chemotherapeutic drug, aiming to overcome drug resistance through a distinctive four-pronged strategy, including modulation of inflammatory tumor microenvironment (TME), induction of ferroptosis, deep tumor penetration, and the combinatory anticancer effects. After clarifying the promotion effects of the cancer associated fibroblasts (CAFs) in chemoresistance, and leveraging our previous elucidation of the anti-inflammatory and ferroptosis-inducing ability of mangiferin, we synthesized mangiferin amphiphile (MMF) and developed a self-assembled carrier-free nanomedicine, named MP, through the self-assembly of MMF and the representative chemotherapeutic drug paclitaxel (PTX).
