Laser-inducedsynthesis of nano-composite Co-CoO-rGO on paper: miniaturized biosensor for alkaline phosphatase detection.

Recent progress in thesynthesise of various nanomaterials has gained tremendous interest and wide applications in various fields. For the first time to the best of our knowledge, this work reports a methodology of ultra-fastsynthesis of cobalt-cobalt oxide-reduced graphene oxide (Co-CoO-rGO (CC-rGO)) composite by laser ablation. The photothermal reduction technique was leveraged to develop the CC-rGO.
