Laserprocessingof biomaterials is the application of laser-based techniques for fabrication and/or analysis of medically-relevant materials and biological systems. introduction light processing laser nano based micro of biomaterials amplification by stimulated emission of radiation (laser) has been used for materials processing since the early 1960s. Tpp is an important method of multiphoton-based laser microand nano-fabrication and should play an important role in producing polymer-based optoelectronic and mems devices, since it offers fabrication of 3d structures below the diffraction limit (witzgall et al. 1998). it is also expected that this method will penetrate many scientific. The use of ultrafast pulsed lasers (i. e. lasers emitting pulses of duration shorter than 10 –12 s) for the micro/nano engineering of biomaterials or materials relevant to biological applications opens up several exciting possibilities in this respect.
Among all these maskless methods, direct laser writing (dlw) is an important and widely adopted micro‐processing technique. based on the nonlinear exposure, the feature size can achieve down to tens of nanometers. however, the speed of dlw is a technical bottleneck. The conference is an ideal platform for scientists and engineers working on laser-based processes on microand nanometer scales for advanced applications. these include wearables, photovoltaics, energy storage systems, batteries, fuels cells, moems, mems/bio-mems, nems, microand nanofluidic devices, which, e. g. apply advanced beam source and beam delivery technologies, including high throughput laser processing with high-speed scanners and advanced parallel processing techniques for.
