    abstract = {Laser-induced graphene (LIG) possesses desirable properties for numerous applications.
However, LIG formation on biocompatible substrates is needed to further augment the
integration of LIG-based technologies into nanobiotechnology. Here, LIG formation on crosslinked
sodium alginate is reported. The LIG is systematically investigated, providing a
comprehensive understanding of the physicochemical characteristics of the material. Raman
spectroscopy, scanning electron microscopy with energy-dispersive x-ray analysis, x-ray
diffraction, transmission electron microscopy, Fourier-transform infrared spectroscopy and x-ray
photoelectron spectroscopy techniques confirm the successful generation of oxidized graphene
on the surface of cross-linked sodium alginate. The influence of laser parameters and the amount
of crosslinker incorporated into the alginate substrate is explored, revealing that lower laser
speed, higher resolution, and increased CaCl<sub>2</sub> content leads to LIG with lower electrical
resistance. These findings could have significant implications for the fabrication of LIG on
alginate with tailored conductive properties, but they could also play a guiding role for LIG
formation on other biocompatible substrates.},
