Maize Protein Zein Based Films for Sustainable Sensing

STATE OF THE ART

Point-of-care (POC) technologies have been gaining interest, since they enable to detect biomolecules in biological fluids quicker and more accurately than conventional techniques. Focusing on the precision medicine of the future, there is also a growth of theragnostics at POC that encourages the use of biocompatible and biodegradable materials. The invention discloses a preparation method of a zein-based film for the deposition of conductive or non-conductive materials, intended for producing optical or electrochemical sensing surfaces for biomolecules detection, and a zein-based biocompatible film for replacing synthetic plastics. The zein film can be used as a direct support for optical (e.g., photonic, colorimetric, fluorescent) and conductive materials. The zein film is suitable for the development of biosensors for any target compound, besides being low-cost and an environmentally friendly approach. Moreover, the zein film is suitable as a bioplastic, due to its biocompatibility and biodegradability. Thus, the present invention regards the area of devices and materials for analyzing biomolecules using optical and electrochemical methods, as well as materials for reducing the environmental impact of human activities.
