“…These patterns can be created or traced by controlling the laser beam focus point with galvanometric scanners or by moving the sample on a high-resolution XYZ stage with a fixed focal point . As the laser uses a wide range of wavelength to interact with the material, this versatility allows the user to add (polymerization), subtract (ablation), or modify different materials without harsh chemicals, preheating of the material, and the need for physical contact between the tools and material allowing the user to create true 3D structures. ,, The few advantages have generated interest in using DLW for the fabrication of many biomedical devices such as stents, prostheses, sensors, drug-delivery devices, and tissue-engineering scaffold. , …”

Fabrication of 3D cell scaffolds has gained tremendous attention in recent years because of its applications in tissue engineering and cell biology applications. The success of tissue engineering or cell interactions mainly depends on the fabrication of well-defined microstructures, which ought to be biocompatible for cell proliferation. Femtosecond-laser-based 3D printing is one of the solution candidates that can be used to manufacture 3D tissue scaffolds through computer-aided design (CAD) which can be efficiently engineered to mimic the microenvironment of tissues. UV-based lithography has also been used for constructing the cellular scaffolds but the toxicity of UV light to the cells has prevented its application to the direct patterning of the cells in the scaffold. Although the mask-based lithography has provided a high resolution, it has only enabled 2D patterning not arbitrary 3D printing with design flexibility. Femtosecond-laser-based 3D printing is trending in the area of tissue engineering and cell biology applications due to the formation of well-defined micro- and submicrometer structures via visible and near-infrared (NIR) femtosecond laser pulses, followed by the fabrication of cell scaffold microstructures with a high precision. Laser direct writing and multiphoton polymerization are being used for fabricating the cell scaffolds, The implication of spatial light modulators in the interference lithography to generate the digital hologram will be the future prospective of mask-based lithography. Polyethylene glycol diacrylate (PEG-DA), ormocomp, pentaerythritol tetraacrylate (PETTA) have been fabricated through TPP to generate the cell scaffolds, whereas SU-8 was used to fabricate the microrobots for targeted drug delivery. Well-designed and precisely fabricated 3D cell scaffolds manufactured by femtosecond-laser-based 3D printing can be potentially used for studying cell migration, matrix invasion and nuclear stiffness to determine stage of cancer and will open broader horizons in the future in tissue engineering and biology applications.

“…[8][9][10][11][12][13][14][15] Regardless of the attractive features of crystals, there is a strong desire to construct on-chip or three-dimensional (3D) devices to implement multifunctions in compact systems. [16][17][18][19] In photonics, such devices are based on structures of optical waveguides. The light propagation can be confined in waveguides in a diffraction-free way due to the total internal reflection, in which the optical intensity is able to reach a high level.…”

“…Previously, people used photolithograph, etching or hightemperature fusion to make the widely investigated microcavities including microdisks, microtoroids, microspheres, microrings and microbubbles, all of which can support high-Q whispering-gallery modes (WGMs). Recently, Xu et al [6] have summarized a newly developed fabrication technique of three-dimensional microcavities using femtosecond lasers. The femtosecond laser processing features with high fabrication resolution.…”
