    Research paper (scientific journal), Joint Work, Accepted,  ISSN  09478396

     View Summary

    In this work, the ablation rate and surface modifications are studied of aluminum nitride ceramic treated by a pulsed nanosecond Nd:YAG laser at four wavelengths—266 nm, 355 nm, 532 nm, and 1064 nm. The ablation depth is presented as a function of the laser fluence and the number of pulses applied. A decrease of the ablation efficiency with the increase of both laser fluence and number of pulses is observed for all wavelengths used. It is found that the laser treatment leads to the formation of a variety of micro and nanostructures on the surface of the material that are strongly dependent on the processing conditions. The laser ablation at the fundamental wavelength leads to the appearance of periodic structures on the surface. Such effect is not observed for the other wavelengths used. It is further found that the laser processing also leads to the formation a conductive layer for all wavelengths. Using a model based on the heat diffusion equation that takes into account the process of ceramic decomposition, the ablation dynamics is followed, and the dependence of the surface layers thickness on the processing conditions is estimated. The results obtained are used to explain the experimentally observed dependences.

     View Summary

    The patterning of electrically conductive structures directly onto the polydimethylsiloxane (PDMS) surface is crucial for the realization of flexible and elastic devices. Herein, defocused femtosecond laser pulses are irradiated for the fabrication of highly crystalline graphitic carbon structures on PDMS and a high electrical conductivity of ≈51.6 S m−1 is achieved. Utilizing the elasticity of PDMS and the high conductivity of fabricated structures, a fingertip-sized pressure sensor, which can detect pressures as low as ≈0.1 Pa, is realized. Moreover, a novel ring-shaped heart rate (HR) monitor, capable of measuring the HR from the index finger, is demonstrated, indicating the potential of fabricated structures in miniature and wearable healthcare applications.

     View Summary

    © 2018 by the authors. Biodegradable polymers have attracted increasing attention in tissue engineering and drug delivery systems owing to their high biocompatibility and biodegradability. Among the various methods for shape forming and modification of biodegradable polymers, laser processing has advantages in a dry processing approach that can process complex-shaped surfaces without using toxic chemical components. This review provides an overview of femtosecond laser processing of biodegradable polymers, especially in the last decade. The interaction mechanism of femtosecond laser pulse and biodegradable polymers, e.g., bond dissociation after laser irradiation, affects the degradable property of biodegradable polymers, which has the potential to control the degradation and sustainability of a structure. Applied studies on controlling cell behavior, tissue scaffolding, and drug release are also described.
