The purpose of this lab is to use synthesized Au nanoparticles to form zein protein film using zein, ethanol and glycerol.
Protocol: Zein protein film formation was carried out using the BSA conjugated nanoparticles. A clear solution of zein (10%w/v) in aqueous ethanol (90%v/v) along with glycerol (30% on zein weight basis) was prepared. Then, the BSA conjugated nanoparticles (10%v/v) was added into this solution. Five grams of this solution was placed in a 9cm diameter petri dish and swirled to coat the dish. It was placed in an 40˚C oven for 24 hours to eventually lead to protein film formation. A texture analyzer was then used in order to determine the mechanical properties of the films containing different samples of BSA conjugated Au nanoparticles.
