The topic of single-use plastic (SUP) has attracted considerable global attention. Even though it has been investigated extensively by the research community, there is no existing literature that succinctly reviews the progress and developments of its uses, associated impacts, viable alternatives, and end-of-life scenarios through the lens of the f...

Various fabric properties are important for different sports applications. In order to improve fabric performance the focus is more on the material features of fabrics rather than the pattern. Fabric properties like moisture management, air permeability, and stretchability depend not only on the materials (the polymer) but also on their assembly in...

Electrospinning of protein-loaded fibers faces many challenges, e.g. burst release owing to segregation of the protein on the fiber surface, loss of activity due to electrospinning conditions, limitation of loading capacity etc. Core–shell electrospinning provides an effective way to electrospin fibers wherein the core can be loaded with bioactive...

Electrospun polymeric fibers are attractive candidates in the development of scaffolds for the tissue engineering and for providing new systems for delivery of bioactive molecules. Co-axial fibers have emerged as an efficient tool to protect the core material from the adverse conditions of electrospinning process, to spin difficult-to-process fluid...

Sustained DNA delivery from polymeric films provides a means for localized and prolonged gene therapy. However, in the case of bioactive molecules such as plasmid DNA (pDNA), there are limitations on the achievable release profiles as well as on the maintenance of bioactivity over time. In this report, the authors have investigated the bioactivity...

Controlled release of hydrophilic entities, such as peptides, proteins and even pDNA, is difficult to accomplish with conventional approaches. This work suggests one possible approach for controlled release of such actives using electrospun core-shell fiber structures. In particular, we propose strategies for partition control of the release. The f...
