The biomaterials are promising for water treatment

gas sensor

energy storage and photocatalysis. However

the traditional preparation processes of the biomaterials are complex

and require toxic organic reagents. Simple and green preparation methods for biomaterials are highly desired. The cold plasma-induced self-assembly of biomolecules at room temperature is simple and green

as it does not use organic reagent

and does not require calcinations

H2 reduction

chemical reduction and photoinduced reduction. By using the plasma-induced self-assembly

biofilm with a height of (1.03±0.14)nm and metal/biomaterial composites with highly dispersed metal nanoparticles (< 10 nm) have been successfully fabricated. However

many fundamental issues about the cold plasma-induced self-assembly

especially its mechanism

are still unsolved. A deep understanding on these problems will allow for controllable and massive syntheses of biomaterials.
