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.
