Nano-fibre optic probe for label-free bioimaging detection

We present 2D nanomaterial-functionalised fibre optic probes for the bioimaging detection of antibodies. Graphene oxide (GO) provides an ideal platform for biophilic binding interface due to its high surface-to-volume ratio and abundant oxygen functional groups. After functionalisation and bio-immobilisation, the fluorescence images reveal that GO-fibre optic probe exhibits significantly stronger fluorescence intensity compared to bare fibre probes. This GO-fibre optic probe can be further developed as a point-of-care medical device for biomedical imaging and portable bio-detection.
