Hierarchical microchannel architecture in chitosan/bioactive glass scaffolds via electrophoretic deposition positive-replica.

Arash Ghalayani Esfahani et al.

Journal of biomedical materials research. Part A, 107(7), 1455-1465 (2019-02-21)

One of the main challenges in the design of scaffolds for cortical bone regeneration is mimicking the highly oriented, hierarchical structure of the native tissue in an efficient, simple, and consistent way. As a possible solution to this challenge, positive

Chitosan stabilizes platelet growth factors and modulates stem cell differentiation toward tissue regeneration.

Alberto Busilacchi et al.

Carbohydrate polymers, 98(1), 665-676 (2013-08-31)

The idea of using chitosan as a functional delivery aid to support simultaneously PRP, stem cells and growth factors (GF) is associated with the intention to use morphogenic biomaterials to modulate the natural healing sequence in bone and other tissues.

Advances in chitosan-based drug delivery vehicles.

Liming Hu et al.

Nanoscale, 5(8), 3103-3111 (2013-03-22)

Within the past few years, chitosan-based drug delivery vehicles have become some of the most attractive to be studied. In contrast to all other polysaccharides, chitosan has demonstrated its unique characteristics for drug delivery platforms, including its active primary amino

Synthesis and characterization of diopside particles and their suitability along with chitosan matrix for bone tissue engineering in vitro and in vivo.

J Pradeep Kumar et al.

Journal of biomedical nanotechnology, 10(6), 970-981 (2014-04-23)

The scaffolds for bone tissue engineering should be porous to harbor the growth of new tissue ingrowths, biodegradable with no toxic end products, and biocompatible with no cytotoxicity. In this study we report that Diopside (CaMgSi2O6) (Dp) particles can be

Chemical modification of chitosan with pH-sensitive molecules and specific ligands for efficient DNA transfection and siRNA silencing.

Bijay Singh et al.

Journal of nanoscience and nanotechnology, 14(1), 564-576 (2014-04-16)

Successful gene therapy depends on the development of efficient and cell-specific gene delivery systems. Currently, animal viral vectors have been mostly used for in vivo and in clinical trials owing to their high transduction efficiency. However, they suffer from numerous
