The development of new medical devices and pharmaceuticals plays an integral role in the medical industry. Both natural and synthetic polymers possess benefits that make them valuable components in therapeutics.
Chitosan is a naturally occurring polysaccharide ideally suited for use in medical supplies, devices, therapeutics, and diagnostics. The unique natural characteristics of chitosan include its cationic, biocompatible, biodegradable, non-toxic, non-immunogenic, and antimicrobial properties.
Collagen molecules play a critical role in tissue architecture and strength, and in cell-matrix interactions as insoluble ligands to regulate the diverse phenotypic activities of cells.
In this article, we discuss issues critical to successful application of the electrospinning technique, including control of individual nanofibers to form secondary structures and assembly of nanofibers into 3D architectures.
The use of hydrogel-based biomaterials for the delivery and recruitment of cells to promote tissue regeneration in the body is of growing interest. This article discussed the application of hydrogels in cell delivery and tissue regeneration.
Microfluidic assembly can efficiently overcome the general disadvantages of polyamine nanoencapsulation of nucleic acids, such as a less defined morphology and composition, polydispersity, and poor reproducibility.
