New Advancements In Biomaterials
Presented by-Pritam Kishore Chakraborty, M.tech,MNDSMSE, IIEST Shibpur
AT A GLANCE• What are BIOMATERIALS?
• Classification of BIOMATERIALS.
• Biopolymers.
• Ongoing applications.
• New advancements.
• Future prospects.
• Conclusion.
What Are Biomaterials?
• A biological or synthetic substance which can be introduced into body
tissue as part of an implanted medical device or used to replace an
organ, bodily function, etc.
• A biomaterial is any substance that has been engineered to interact
with biological systems for a medical purpose - either a therapeutic
(treat, augment, repair or replace a tissue function of the body) or a
diagnostic one.
But still a lot of ambiguity...
BIOMATERIAL CLASSIFICATION• Based On Material Used:-
1. Metallic Biomaterials.
2. Ceramic Biomaterials.
3. Polymer Biomaterials.
• Based On Mode Of Application:-
1. Ex Vivo.
2. In Vivo.
Metallic Biomaterials
• Implants,dentures etc. made of stainless steel,Ti alloys,Co-Cr-Mo alloys.
Metallic Biomaterials
Ceramaic Biomaterials• Al2O3,cermets for implants etc.
Polymeric Biomaterials(biopolymers)
• Cellulose derivatives,chitin,nucleic acids etc.
Why Biopolymers?
• Biodegradable,Biocompatible,Bio-responsive,Versatile,Easy Synthesis & Inexpensive.
Ongoing Applications of biopolymers
• Nano Bio-polymers.
Drug Delivery System
• ADVANTAGE-Can Access Previously Inaccessible Body Parts.
• Example:-Blood Brain Barrier.
Drug Delivery System
Drug Delivery System• Finds uses in:-
• Kidney dialysis.
• Neurological disorders.
• Cardiovascular diseases.
• Diabetes treatment.
• Cancer treatment.
• Pre-natal problems & many more…
Artificial Tissue Synthesis• SKIN SCAFFOLDS- In Other Words Artificial Skin For Burn Patients And
Acid Attack Victims.
Artificial Tissue Synthesis
•Biopolymers actually can help in giving them a new life.
Artificial Tissue Synthesis
Other Applications
• Carbon Fiber-prosthetics.
Other Applications
The Road Ahead..
Remarks
• Bio-Materials are mainly classified into Metals, Ceramics, Polymers and sometime the combination of all three.
• Now more research in focused into use of Nano-Biomaterials and Bio-Polymers for their aesthetic value ,affectivity and versatility.
• New research avenues are giving a hope for a better and healthy life for all.
Conclusion-Tip Of The Iceberg.
• The scope for bio-materials till now is untapped and has unlimited potential,
both in case of industrial production and applications , and if used judiciously
it promises to provide better life for everyone on this planet.
