Description

General description

L-Ascorbic acid or vitamin C is a water-soluble vitamin found in various foodstuffs. Benefits of vitamin C may include protection against immune system deficiencies, cardiovascular disease, hyperpigmentation, skin protection, anti-aging, iron absorption, and red blood cell production. It is also useful in the biosynthesis of collagen, L-carnitine, and neurotransmitters.

Application

L-ascorbic acid (L-AA) can be used as a reducing as well as a capping agent in the synthesis of well-dispersed metal nanoparticles and also in the reduction of graphene oxide sheets.

Its immunostimulant derivatives play an important role in cell regulation.

We demonstrated that the individual graphene oxide sheets can be readily reduced under a mild condition using L-ascorbic acid (L-AA). This simple approach should find practical applications in large scale production of water soluble graphene.
