New composite materials made up of nanofibers and hydrogel as biomimetic scaffolds for human pluripotent stem cell culture

Inulin for Cancer Therapy: Present and Perspectives

Inulin is an extremely adaptable polysaccharides consisting of glucopyranose end-capped (β-1,2) fructose repeating units and, as it is, can be classified as an inherently multifunctional polymeric scaffold. It may be further functionalized employing mild conditions to give rise desired biological and physicochemical properties exploitable for targeted anticancer applications (e.g., active targeting toward specific cytotypes, self-assembling behavior, selective cytoxicity and hyperthermia features). In this review, the main chemical features and the inulin derivatives applications in the field of targeted anticancer therapy is reported and discussed

Graphene nanosystems as supports in siRNA Delivery

The nature of graphene-based nanosystems, as well as the possibility to synthesize them at low cost, have made them in the last few years, an interesting proposition in tumour therapy as a drug delivery system. Here, a reduced form of graphene oxide (RGO) has been synthesized and conjugated with a specific antibody for active targeting against tumour cells (RGOY). Furthermore, its bi-dimensional nature permits also p- p stacking interactions with planar molecules like siRNA (RGOY-siRNA). All these nano-complexes were characterized by DLS and DSC analysis, TEM and Raman spectroscopy and their biocompatibility was demonstrated by viability assay on cell line ECV 304. The system is able to be …
