Applications of biomaterials in cancer therapy has been limited to drug delivery
systems and markers in radiation therapy. In this article, we introduce the
concept of phase-functionalization of silicon to preferentially select cancer
cell populations for survival in a catalyst and additive free approach. Silicon
is phase-functionalized by the interaction of ultrafast laser pulses, resulting
in the formation of rare phases of SiO2 in conjunction with differing silicon
crystal lattices. The degree of phase-functionalization is programmed to dictate
the degree of repulsion of cancer cells. Unstable phases of silicon oxides are
synthesized during phase-functionalization and remain stable at ambient
conditions. This change in phase of silicon as well as formation of oxides
contributes to changes in surface chemistry as well as surface energy. These
material properties elicit in precise control of migration, cytoskeleton shape,
direction and population. To the best of our knowledge, phase-functionalized
silicon without any changes in topology or additive layers and its applications
in cancer therapy has not been reported before. This unique programmable
phase-functionalized silicon has the potential to change current trends in cancer
research and generate focus on biomaterials as cancer repelling or potentially
cancer killing surfaces.
