“…The concept of environmentally friendly optical devices 41,42 has also been demonstrated by the fabrication of a whispering-gallery-mode micro-laser 53 . Figure 6b shows the smoothness and fabrication accuracy of the disk structure that is necessary to control the gallery-mode.…”

“…Assuming that the cross-linking proceeds as a random process, one would expect that the resulting structures would be degradable because the majority of normal peptide or organic bonds would be retained. Sun et al showed changes in proteinaceous structures within two weeks of exposure to collected raindrops, such that the surface became rougher, small features were reduced and structural elements seemed less supportive 41 . These observations suggested that complete degradation could occur within several months, although this was not confirmed.…”

“…In addition to the pH-tunable microlenses introduced in the previous section, a flexible micro-sized kinoform phase lens (KPL) 41 and a responsive whispering-gallery-mode micro-laser 53 have been fabricated based on this concept. Figure 6a presents a KPL formed from polydimethylsiloxane (PDMS) as a flexible diffractive device with good surface properties and a suitable lifetime in an aqueous environment 41 . Three important aspects of this device are its quality, flexibility and capacity for biodegradation.…”

“…These functions include not only the diverse intrinsic properties of native proteins such as charge transfer, molecule modification and cell-cell communication, but also engineered functions of synthetic proteins. Consequently, the resulting protein structures have been applied to fabricate functional microdevices, including pH-sensitive actuators 39,40 and optical microcomponents 41,42 . The integration of proteinaceous microstructures into commercial polymers 43 and protein-polymer hybrids 44 has also been found to increase mechanical strength.…”

Proteins are a class of biomaterials having a vast array of functions, including the catalysis of metabolic reactions, DNA replication, stimuli response and transportation of molecules. Recent progress in laser-based fabrication technologies has enabled the formation of three-dimensional (3D) proteinaceous micro-and nano-structures by femtosecond laser cross-linking, which has expanded the possible applications of proteins. This article reviews the current knowledge and recent advancements in the femtosecond laser cross-linking of proteins. An overview of previous studies related to fabrication using a variety of proteins and detailed discussions of the associated mechanisms are provided. In addition, advances and applications utilizing specific protein functions are introduced. This review thus provides a valuable summary of the 3D micro-and nano-fabrication of proteins for biological and medical applications.

“…The fabricated structures have similar or superior mechanical properties to native silk fibroin and can readily interface with live cells [85]. Another study used femtosecond laser direct writing to fabricate diffraction gratings in protein films [87,88]. Bovine serum albumin was coated to a polydimethylsiloxane substrate and a 120-fs titanium-sapphire laser was used to cross-link the protein to form a grating structure.…”

Optical technologies are essential for the rapid and efficient delivery of health care to patients. Efforts have begun to implement these technologies in miniature devices that are implantable in patients for continuous or chronic uses. In this review, we discuss guidelines for biomaterials suitable for use in vivo. Basic optical functions such as focusing, reflection, and diffraction have been realized with biopolymers. Biocompatible optical fibers can deliver sensing or therapeutic-inducing light into tissues and enable optical communications with implanted photonic devices. Wirelessly powered, light-emitting diodes (LEDs) and miniature lasers made of biocompatible materials may offer new approaches in optical sensing and therapy. Advances in biotechnologies, such as optogenetics, enable more sophisticated photonic devices with a high level of integration with neurological or physiological circuits. With further innovations and translational development, implantable photonic devices offer a pathway to improve health monitoring, diagnostics, and light-activated therapies.

Direct light‐to‐work conversion enables manipulating remote devices in a contactless, controllable, and continuous manner. Although some pioneering works have already proven the feasibility of controlling devices through light‐irradiation‐induced surface tension gradients, challenges remain, including the flexible integration of efficient photothermal materials, multifunctional structure design, and fluidic drag reduction. This paper reports a facile one‐step method for preparing light‐driven floating devices with functional surfaces for both light absorption and drag reduction. The direct laser writing technique is employed for both arbitrary patterning and surface modification. By integrating the functional layer at the desired position or by designing asymmetric structures, three typical light‐driven floating devices with fast linear or rotational motions are demonstrated. Furthermore, these devices can be driven by a variety of light sources including sunlight, a filament lamp, or laser beams. The approach provides a simple, green, and cost‐effective strategy for building functional floating devices and smart light‐driven actuators.
