Abstract

In colloidal suspensions with nonlinear optical techniques, it is possible to overcome strong scattering effects and form a self-induced waveguide of light. Previous studies of dielectric, metallic, and biological colloidal suspensions show waveguide formation for spherical, elliptical, and disc-like particles. In all the previous works, the particle can be approximated as a spherical particle. In this work, we study light propagation and the possibility to form a waveguide with long helical-shaped particles. In our study, we extract the strawberry DNA using the CTAB protocol, resuspend DNA in DI water, and study the possibility to form biological waveguides in DNA suspensions at different wavelengths. Since extracted DNA are very long helical-shaped strands, which coil with each other, DNA displays a "topologically frustrated" inability to move and can’t form a typical biological waveguide.
