Scientists have developed ultra-thin heteroprotein films with excellent thermal, mechanical and pH stability which can pave the way for expanding applications of thin films in biomedical and food packaging industries.



  • It has been developed by Institute of Advanced Study in Science and Technology (IASST), Guwahati, an autonomous institute under the Department of Science and Technology.
  • These films consists of two globular proteins: bovine serum albumin (BSA) and lysozyme (Lys).
  • They used the technique called using Langmuir-Blodgett (LB) technique which gives the films thickness in the order of nanometer.
  • These films are much thinner as compared to the other protein or plastic films. They are soft and thin and have the advantage of being more flexible than the other films.
