AbstractWe present a method to develop single-wall carbon nanotube (SWCNT)/polymer composites into arbitrary three-dimensional micro/nano structures. Our approach, based on two-photon polymerization lithography, allows one to fabricate three-dimensional SWCNT/polymer composites with a minimum spatial resolution of a few hundreds nm. A near-infrared femtosecond pulsed laser beam was focused onto a SWCNT-dispersed photo resin, and the laser light solidified a nanometric volume of the resin. The focus spot was three-dimensionally scanned, resulting in the fabrication of arbitrary shapes of SWCNT/polymer composites.SWCNTs were uniformly distributed throughout the whole structures, even in a few hundreds nm thick nanowires. Furthermore, we also found an intriguing phenomenon that SWCNTs were self-aligned in polymer nanostructures, promising improvements in mechanical and electrical properties. Our method has great potential to open up a wide range of applications such as micro-and nanoelectromechanical systems, micro/nano actuators, sensors, and photonics devices based on CNTs. Main Text

Abstract:The current demand for fabricating optical and photonic devices displaying high performance, using low-cost and time-saving methods, prompts femtosecond (fs)-laser processing as a promising methodology. High and low repetition femtosecond lasers enable surface and/or bulk modification of distinct materials, which can be used for applications ranging from optical waveguides to superhydrophobic surfaces. Herein, some fundamental aspects of fs-laser processing of materials, as well as the basics of their most common experimental apparatuses, are introduced. A survey of results on polymer fs-laser processing, resulting in 3D waveguides, electroluminescent structures and active hybrid-microstructures for luminescence or biological microenvironments is presented. Similarly, results of fs-laser processing on glasses, gold and silicon to produce waveguides containing metallic nanoparticles, analytical chemical sensors and surface with modified features, respectively, are also described. The complexity of fs-laser micromachining involves precise control of material properties, pushing ultrafast laser processing as an advanced technique for micro/nano devices.

“…The average energy fluence per pulse was set to 1.2 J/cm 2 according to our previous experience [3] and the machining direction was along the minor axis of the pulsing laser spot with a scanning speed of 3.0 mm/sec. The SHG images of the machined chicken tendon were captured by a home-built, point-scanning multiphoton microscope with a laser source of the ultrafast oscillator [3]. The excitation wavelength of the SHG signal was 750 nm with relatively low energy fluence per pulse of 28.4 mJ/cm 2 to avoid ablating non-targeted regions.…”

“…Additionally, second harmonic generation (SHG) can be employed to directly obtain non-centrosymmetric contour information in specimens, such as collagen within tissue [2]. Due to deeper penetration depth, significantly reduced off-focus photobleaching, and minimum invasion, MPE is not only effective in nonlinear optical imaging, but is also very useful in fabrication [3][4][5] and machining [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] A short pulse width indicates a higher peak power at lower average energy, and can easily confine the reaction region in the focal spot via a high numerical aperture (NA) objective [13]. Therefore, this approach is suitable for biomedical micro/nano-processing ablation of biological materials and tissues [9][10][11][12][13][14][15][16][17][18][19][20][21].…”

Abstract:In this study, a temporal focusing-based high-throughput multiphoton-induced ablation system with axially-resolved widefield multiphoton excitation has been successfully applied to rapidly disrupt biotissues. Experimental results demonstrate that this technique features high efficiency for achieving large-area laser ablation without causing serious photothermal damage in non-ablated regions. Furthermore, the rate of tissue processing can reach around 1.6 × 10 6 μm 3 /s in chicken tendon. Moreover, the temporal focusing-based multiphoton system can be efficiently utilized in optical imaging through iterating high-throughput multiphoton-induced ablation machining followed by widefield optical sectioning; hence, it has the potential to obtain molecular images for a whole bio-specimen.
