Glass electronics inspire the emergence of smart functional surfaces. To evolve this concept to next level, developing new strategies for scalable, inexpensive, and electrically conductive glass-based robust nanocomposites is crucial. Graphene an attractive material as a filler; however, integrating it firmly into glass with no energy-intensive sintering, melting, or harsh chemicals has not been possible until now. Moreover, these methods have very limited capability fabricating patterns electronic circuits. In work, (160 OΩ sq-1 ) resilient nanocomposite between graphene achieved via single-step laser-induced backward transfer (LIBT). Beyond conventional LIBT involving mass transfer, approach simultaneously drives chemical transformations in including silicon compound formation oxide (GO) reduction. These processes take place together generation highest-quality laser-reduced GO (rGO) reported date (Raman intensity ratio ID /IG = 0.31) its integration glass. The rGO-LIBT further functionalized silver achieve highly sensitive (10-9 m) dual-channel plasmonic optical electrochemical sensor. Besides electrical circuit demonstration, electrothermal heater fabricated that reaches temperatures above 300 °C continuously operates over 48 h.
