Ultra-Thin Heteroprotein Films

Context: As per the recent research, newly developed ultrathin heteroprotein film is a better alternative to isolated protein films. 

About Ultra-Thin Heteroprotein Films: 

Scientists have recently developed ultra-thin heteroprotein films with excellent mechanical thermal and pH stability. This can pave the way for expanding applications of thin films in food packaging industries and biomedical. These films are much thinner in comparison to the compared to the other protein or plastic films. They are thin and soft and have the advantage of being more flexible than the other films.

A research group from the Institute of Advanced Study in Science and Technology (IASST), Guwahati, has developed ultrathin monolayer protein films. It consists of two globular proteins: lysozyme (Lys) and bovine serum albumin (BSA). They used the Langmuir-Blodgett (LB) technique which gives the film thickness in the order of a nanometer. Films of such protein complexes of BSA and Lys can be useful for fabricating highly stable biodegradable thin films of different protein complexes for expanding their applications in the area of thin-film technology. 

Diverse physicochemical methods such as parameter alteration or incorporation of different fatty acids or polyol moieties (glycerol, starch, gelatin, etc.) into this protein complex can make the film free standing for diverse applications. 

The work was recently published in the esteemed journal of Food Hydrocolloids under the reputed Elsevier publishers.
