Ultra-Thin Heteroprotein Films


Consider the following statements:

  1. Recently, Indian scientists developed ultra-thin heteroprotein films which can pave the way for expanding applications of thin films in biomedical and food packaging industries.
  2. The ultrathin monolayer protein films consist of two globular proteins: bovine serum albumin (BSA) and lysozyme (Lys).
  3. The scientists used the Langmuir-Blodgett (LB) technique which gives the films thickness in the order of nanometer.
