Controlling microbial growth is crucial for many biomedical, pharmaceutical and food industry applications. In this paper, we used a femtosecond laser to microstructure the surface of chitosan, a biocompatible polymer that ...

The concept behind drug delivery systems is to provide the correct amount of pharmaceutical compound to a desired body part within a predefined timespan. It can be made of various materials such as liposomes, niosomes, ...

Irradiation of materials such as iron and silicon with single nanosecond laser pulses produces nanostructures on its surfaces. Nevertheless, the deposition before irradiation of thin films on the silicon?s surfaces can ...

Novel materials have been developed to meet the increasing mechanical, electrical and optical properties required for technological applications in different fields of sciences. Among the methods available for modifying ...

3D-waveguides containing silver nanoparticles have been fabricated in tungsten lead-pyrophosphate glass by femtosecond laser micromachining. Nucleation and growth of nanoparticles occur in a single step process when high ...

We report on the femtosecond-laser micromachining of poly(methyl methacrylate) (PMMA) films doped with nonlinear azoaromatic chromophores: Disperse Red 1, Disperse Red 13 and Disperse Orange 3. We study the conditions for ...

The use of laser light to modify the material's surface or bulk as well as to induce changes in the volume through a chemical reaction has received great attention in the last few years, due to the possibility of tailoring ...

This work presents a particular application corresponding to waveguides manufactured by the femtosecond laser micro-machining technique. More specifically we have conducted the study, design, simulation and implementation ...
