Fabrication of functional silk fibroin microstructures has extensive applications in biotechnol. and photonics. Considerable progress has been made based on lithog. methods and self-assembly approaches. However, most methods require chem. modification of silk fibroin, which restricts the functionalities of the designed materials. At the same time, femtosecond laser-induced forward transfer (fs-LIFT) has been explored as a simple and attractive processing tool for microprinting of high-resolution structures. The authors propose the use of LIFT with fs-pulses for creating high-resolution structures of regenerated silk fibroin (SF). Furthermore, upon adding Eu3+/Tb3+ complexes to SF, the authors have been able to demonstrate the printing by LIFT of luminescent SF structures with a resolution ∼2μm and without material degradation This approach provides a facile method for printing well-defined two-dimensional (2D) micropatterns of pure and functionalized SF, which can be used in a wide range of optical and biomedical applications. In the experiment, the researchers used many compounds, for example, 4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Application In Synthesis of 4,4′-Dimethyl-2,2′-bipyridine)
4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6) is used as a chemical Intermediate. It can be used for the determination of ferrous and cyanide compounds.Application In Synthesis of 4,4′-Dimethyl-2,2′-bipyridine Furthermore, 4,4′-Dimethyl-2,2′-bipyridine is used in the synthesis of a series of o-phenanthroline-substituted ruthenium(II) complexes.
