aResearch and development of Bio-degradable polymer is one of most active areas in material science recently because its importance in national resource security and environment impact. However, current starch based feed stock for bio-plastic are competing with the use of agriculture land for food....
(Smeak, 1998).Polydioxanoneis stiff and more difficult to handle thanDexonorVicryl, but slides easily through tissue.PDSII was developed to improve the handling characteristics of the original form. It has low reactivity and maintains integrity in infected tissues and in urine so is often used...

Main driving force to grow these NPs within the cavities of CP is the presence of free oxygens of one of the monodentate carboxylate groups of BDC ligand. These free oxygens act as anchoring sites for the metal ions of the metal precursors. Chemical and physical characteristics of the NPs ...
Product characteristics and Application:By poly (p-dioxanone) made of bio compatibility is good, after the in vivo degradation product by the metabolism out of the body, no harmful and toxic side effects on the human body. At present, it is widely used in the fields of medicine, absorbable...
