Sorbitol as an efficient reducing agent for laser-induced copper deposition

► Copper lines were deposited on the surface of ceramics using sorbitol. ► Sorbitol as a reductant leads to deposition of conductive copper lines. ► Topology of deposits was studied by SEM and scanning probe microscopy. ► Elemental composition of deposited lines was studied by EDX analysis. ► Electrical properties of copper were examined by impedance spectroscopy.
