Techniques To Control Polymersome Size

2015

Polymersomes as synthetic analogues of liposomes appear frequently in relevant literature as promising candidates for a wide range of different applications including drug delivery, theranostic multitools, and nanoreactors. In particular, as nanotransporters for nanomedical applications in vivo, requirements concerning the reproducible manufacturing and reliable size control are extremely high. This Perspective highlights the importance of size control especially in the context of nanomedicine and gives an overview of the theoretical background of amphiphilic self-assembly leading to different preparation methods, where their feasibility of controlling polymersomes’ size is discussed.

Microphase separation in ternary ABC block copolymers: Ordering control in molten diblock AB copolymers by attaching a short strongly interacting C b…

1997

Some specific features of the microphase separation in molten ternary ABC triblock copolymers (in particular, modifications of the molten AB diblock copolymers by attaching a short third block C strongly incompatible with both A and B blocks) are studied rigorously within the framework of the weak segragation approach. It is shown that via such a modification one can control both the stability as to the microphase separation transition (i.e., the corresponding spinodal temparatures) and the smoothness of such a transition. Two modes of such modifications for every composition are studied in detail:  (i) those resulting in the minimal spinodal temperatures and (ii) those that result in the s…
