What is the fate of NH2 and OH groups in chitosan when we use it as a reducing agent to produce metal nanoparticles?

It is said that NH2 and OH groups are involved in the reduction process of metal ions during nanoparticle synthesis. Do these groups get converted to some other groups (their oxidised forms) as a...
