Indian Patent Applicaton No: 

2308/DEL/2008

Department: 

Patent Category: 

Overview: 

Quick synthetic route to prepare biodegradable polymers of glycolic acid (PGA), lactic acid (PLA) & co polymer of both (PLG).

Key Features: 

  • The method involves irradiating the starting materials to microwave irradiation under solvent & catalyst free conditions with an exposure time of about 12-150 mins as compared to 6-12 hrs through conventional thermal polymerization involving a catalyst.
  • The PLG polymer shows very good encapsulation efficiency to nano encapsulate tuberculosis drugs such as Rifampicin.

Applications: 

  • Sustained drug release for tuberculosis/anti-cancer drugs.
