What is biodegradable material
The term biodegradable is used to describe materials that decompose through the actions of bacteria, fungi, and other living
organisms -simply put it has the ability to break down or decompose back into the natural environment without causing harm
Examples of well known biodegradable materials used in medical industries are PLLA, PLGA, PGA, PDO and PCL
What is PLLA
Poly(L-lactide) is a biodegradable material with good bio-absorbability and bio-compatibility. After degradation in the body, PLLA
products are excreted by metabolism and thus has no harmful side effects to the human body. It is for these reasons that PLLA
products are currently widely used in the field of medicine, such as for one-time infusion equipment, medical surgical suture, drug
delivery carriers, tissue engineering scaffolds, bone anchors, injectable microcapsules, microspheres, implants, elastomermaterials
for organ support, etc.
Mechanism
-PLLA(Poly-L-lactic acid)
-Polymer of Lactic acid
-Lactic acid -> CO2+ H2O
PLLA immune reaction
Some PLLA Eaten by macrophage
-By immune reaction activate fibroblast ro produce collagen The other PLLA remain in human body- half life 3years
Mechanism and technique - II
