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

[Display omitted] ► 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. We have pioneered in revealing the fact that sorbitol may be used as an efficient reducing agent in the process of laser-induced copper deposition from solutions; in this case, it is possible to obtain copper lines much higher quality than by using conventional formalin.
