Fluid Cells Fabrication in Sol-Gel and Porous Glass

Abstract : We investigate laser treatment regimes suitable for the fabrication of the isolated cells in a porous silica glass and a sol-gel film. Three-dimensional structures are produced as a result of the porous glass densification induced by femtosecond laser pulses. We also demonstrate that CO2 laser can be used to form such structures in the sol-gel film deposited on the glass. In the porous glass, barriers with various permeability were created, which were used as walls in fluid cells. Laser-induced microrelief formation on the surface of the sol-gel film provides isolation for the separated porous cells. The impermeability of porous cells is tested by impregnation them with different dyes (rhodamine 6G, fuchsine, etc.).
