Soy protein amyloid-carbon hybrid membranes for water purification

Human activities such as industrialization, power generation and extraction of natural resources have produced significantly high levels of pollutants, including certain heavy metals and metal cyanides, which contaminate water bodies around the world. Existing technologies for the purification of p...

description Human activities such as industrialization, power generation and extraction of natural resources have produced significantly high levels of pollutants, including certain heavy metals and metal cyanides, which contaminate water bodies around the world.

A novel approach has been suggested by Bolisetty et al.,utilizing carbon and amyloid hybrid membranes to filter heavy metal pollutants, which can address the limitations of existing technology. This report will demonstrate the optimization of amyloid fibril formation from soy protein isolate (SPI), atomic force microscopy (AFM) imaging of the amyloid fibrils and the fabrication of a lab-scale carbon and SPI amyloid hybrid membranes.
