Photon-assisted Bio Nanopolymers for Applications of Drug Delivery, Diagnosis and Would Healing

摘要

Biopolymers are valuable complex materials. They attract the attention of many scientists, engineers and medical professionals for application research. The focus of this research is a baseline assessment of valuable nanosized biopolymers, chitosan. As ordinary polymers, nanosized biopolymers are visualized as natural and synthetic polymers. Hence, systematic descriptions of nanosized biopolymers, the synthesis methods, characterization methods, and biomedical application will be presented. In this regard, the photon-activated green synthesis of chitosan nano particles is illustrated. The effect of photon on the cry stallo graphic bond of chitosan and degradations of solid edible fungi in the green synthesis process is presented. Hence, the effect ofphoton of optimum energy on producing instability and breaking the bond between chitosan functional groups is presented. Properties such as biodégradations, biocompatibility, photocatalytic activity, sensitivity, and fluorescence of nanosized biopolymer is reviewed. Due to its peculiar physio-chemical properties, such as electrical and thermal stability, chitosan is preferred in biomedical applications as diagnosis, cell/tissue imaging and soft tissue imaging, therapy, wound healing, and nano carrier of drug delivery. Theoretically, the drug delivery and kinesis processes are determined by translational and rotational vibrations caused by angular momenta ofhydroxyl bond in the functional group.
