“…Biophotonic devices based on optical forces are powerful tools for single cell study and manipulation without physical contact [108][109][110]. The exploitation of optical forces for analysis at single cell level provides significant information, opening new scenarios for the understanding of basic biological mechanisms and for the early detection of several diseases.…”

This paper provides an overview of the rather new field concerning the applications of femtosecond laser microstructuring of glass to optofluidics. Femtosecond lasers have recently emerged as a powerful microfabrication tool due to their unique characteristics. On the one hand, they enable to induce a permanent refractive index increase, in a micrometer-sized volume of the material, allowing single-step, three-dimensional fabrication of optical waveguides. On the other hand, femtosecond-laser irradiation of fused silica followed by chemical etching enables the manufacturing of directly buried microfluidic channels. This opens the intriguing possibility of using a single laser system for the fabrication and three-dimensional integration of optofluidic devices. This paper will review the state of the art of femtosecond laser fabrication of optical waveguides and microfluidic channels, as well as their integration for high sensitivity detection of biomolecules and for cell manipulation.

“…In recent years, this field experienced a tremendous development due to the observation of novel mechanisms of light-matter coupling in optically bounded structures and broad application of chip-scale optical devices for particle trapping. The most notable advances include the use of diffractionless and/or engineered optical beams such as Bessel, 4,5 Airy, 6 optical lattices, 7 miniaturized fiber-optics tweezers 8 and electromagnetic fields in optically bounded structures. [9][10][11] These approaches stimulated observations of optical pulling forces 12 and optical lift 13 effects.…”

Resonant light pressure effects can open new degrees of freedom in optical manipulation with microparticles, but they have been traditionally considered as relatively subtle effects. Using a simplified two-dimensional model of surface electromagnetic waves evanescently coupled to whispering gallery modes (WGMs) in transparent circular cavities, we show that under resonant conditions the peaks of the optical forces can approach theoretical limits imposed by the momentum conservation law on totally absorbing particles. Experimentally, we proved the existence of strong peaks of the optical forces by studying the optical propulsion of dielectric microspheres along tapered microfibers. We observed giant optical propelling velocities ,0.45 mm s 21 for some of the 15-20 mm polystyrene microspheres in water for guided powers limited at ,43 mW. Such velocities exceed previous observations by more than an order of magnitude, thereby providing evidence for the strongly enhanced resonant optical forces. We analyzed the statistical properties of the velocity distribution function measured for slightly disordered (,1% size variations) ensembles of microspheres with mean diameters varying from 3 to 20 mm. These results demonstrate a principal possibility of optical sorting of microspheres with the positions of WGM resonances overlapped at the wavelength of the laser source. They can be used as building blocks of the lossless coupled resonator optical waveguides and various integrated optoelectronics devices.

“…The next method that is often used in 3D nanoscaled patterning is two or multi photon lithography [92,93]. This method was developed to overcome the depth resolution constraints of single-photon stereolithography [94,98]. A photopolymer is radiated with near infrared light.…”
