The use of biomaterials for gene delivery can potentially avoid many of the safety concerns with viral gene delivery. However, the efficacy of polymeric gene delivery methods is low, particularly in vivo. One significant concern is that the interior and exterior composition of polymeric gene delivery nanoparticles are often coupled, with a single polymer backbone governing all functions from bi...

Currently, 33 gene-therapy drugs/products have been approved in the clinic. Over 3000 completed and ongoing clinical gene therapy trials reported worldwide. The development/maturation of tools for manipulation delivery, as well molecular advances diagnosis genetic diseases, played a central role therapy, which greatly revolutionized field. Versatile diverse manipulations deliveries, with possib...

Hydrogels can promote desirable cellular phenotype by mimicking tissue-like stiffness or serving as a gene delivery depot. However, nonviral gene delivery inside three-dimensional (3D) hydrogels remains a great challenge, and increasing hydrogel stiffness generally results in further decrease in gene delivery efficiency. Here we report a method to enhance nonviral gene delivery efficiency insid...

objective: curcumin, is the active component in turmeric (curcuma long). this agent induces apoptosis via inhibiting various signaling pathways. however, its poor aqueous solubility prevents its widespread application. in this study, dendrosomes with water-solubility, nano-sized dimensions and nontoxic properties, was used for curcumin delivery to cells. materials & methods: in the present...
