Photoluminescent Graphene Oxide Ink to Print Sensors onto Microporous Membranes for Versatile Visualization Bioassays

Herein, we report photoluminescent graphene oxide
(GO) paper-like sensors for the ultrasensitive visual bioassays
of peptide, protein, and DNA. GO nanosheets are a two
dimensional oxidized derivative of graphene, which can be
easily exfoliated from graphite in high yield under simple
oxidizing conditions. Owing to the huge surface area and
a thickness of several nanometers,the ultrathin flexible
nanosheets can easily be assembled into the form of paper
sheets or directly fabricated on solid substrates.
Furthermore, GO bears numerous phenol hydroxy and epoxy
groups at the basal plane and carboxylic groups at the lateral
edge,thus providing the direct interaction with biological
species and the flexibility of chemical modification.
In principle, these features make GO nanosheets an excellent
candidate as basic materials for paper chemosensors. How-
ever, common GO nanosheets possess a finite electronic
bandgap and are usually used as a highly efficient fluores-
cence quencher in many reported biosensors.
The lack of signal output capability greatly limit application in colori-
metric paper sensors. On the other hand, unmodified GO
nanosheets can emit a weak fluorescence at about 550 nm.
In recent work, highly photoluminescent GO nanosheets
were successfully synthesized through the amine reaction and
ring-opening amination at the surface of GO nanosheets.
The emissive peak at 440 nm exhibits a large blue-shift
relative to that of pure GO. Generally, the weak emissions of
GO are attributed to a large number of conjugated aromatic
sp2 clusters at GO nanosheets. When the epoxy rings at GO
nanosheets are opened by the present amination reaction, the
degree of sp2 conjugation will largely be reduced, making the
emissive peak exhibit a large blue shift.
