Polymersomes are exciting self-assembled structures with great potential in pharmaceutical applications. A systematic investigation of a novel series methacrylate-based polymersomes is reported this study. Five well-defined ABA triblock copolymers being based on tri(ethylene glycol) methyl methacrylate and B 2-(diethylamino)ethyl (DMAEMA) were synthesized using living polymerization method. The...
Giant cell-like polymer vesicles, polymersomes, made from the diblock copolymer poly(ethylene oxide)-polybutadiene (PEO-PBD), have bilayer structures similar to the cell membrane but have superior and tunable properties for storage and stability. We have modified the terminal hydroxyl of the hydrophilic block with biotin-lysine (biocytin), a biologically derived group that imparts specific adhe...
Curcumin is a hydrophobic polyphenol extracted from the plant curcuma longa with establishedanticancer properties. However, curcumin benefits have been impaired by its very low watersolubility, low absorption, rapid metabolism and clearance from the body. Recently,nanotechnology promises to be helpful in development of drugs delivery systems by recentadvances in macromolecular design of nanocar...
Traditional cancer treatments contain several limitations such as incomplete ablation and multidrug resistance. It is known that photodynamic therapy (PDT) is an effective treatment for several tumor types especially melanoma cells. During the PDT process, protoporphyrin IX (PpIX), an effective photosensitizer, can selectively kill cancer cells by activating a special light source. When tumor c...
The field of therapeutics is evolving to include a greater proportion of higher molecular weight, hydrophilic biological compounds. To cater for this new era in healthcare the concomitant development of appropriate drug delivery systems is essential to aid cellular permeation. In this manuscript we present the synthesis, characterisation and biological evaluation of a charge neutral polymersome...
