Abstract:Nanocellulose has become an attractive biodegradable
material for
surface-enhanced Raman scattering (SERS) sensors. However, the development
of nanofibrillar cellulose-based SERS substrates that are simultaneously
flexible, highly sensitive, uniform, and stable remains a great challenge.
Herein, a highly sensitive, reliable, and flexible gold nanoparticle-decorated
bacterial nanocellulose (AuNPs@BNC) SERS substrate with three-dimensional
(3D) high-density hot spots was constructed by the combination of
in situ… Show more
