Poly(acrylic acid)-capped and dye-loaded graphene oxide-mesoporous silica : a nano-sandwich for two-photon and photoacoustic dual-mode imaging

Poly(acrylic acid)-capped and dye-loaded graphene oxide-mesoporous silica : a nano-sandwich for two-photon and photoacoustic dual-mode imaging

Growth of mesoporous silica on both sides of graphene oxide affords a nano-sandwich (NS) material. A two-photon active dye is then loaded into the mesopores of the NS followed by sealing with poly(acrylic acid). The obtained hybrid exhibits low cytotoxicity and excellent capability for two-photon an...

Description
Summary:Growth of mesoporous silica on both sides of graphene oxide affords a nano-sandwich (NS) material. A two-photon active dye is then loaded into the mesopores of the NS followed by sealing with poly(acrylic acid). The obtained hybrid exhibits low cytotoxicity and excellent capability for two-photon and photoacoustic dual-mode bioimaging.
