Femtosecond laser patterning of the biopolymer chitosan for biofilm formation
(2016-08-19)
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 ...
Controlled drug delivery system by fs-laser micromachined biocompatible rubber latex membranes
(Elsevier B.V., 2020-03-15)
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, ...
Femtosecond lasers for processing glassy and polymeric materials
(Universidade Federal de São Carlos - Departamento de Engenharia de MateriaisSão Carlos, 2014-03)
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 ...
Femtosecond laser waveguide micromachining of PMMA films with azoaromatic chromophores
(OPTICAL SOC AMER, 2008)
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 ...
Microestruturas em fibras óticas e estruturas planares gravadas por microusinagem com laser de femtosegundos: controle, produção e caracterização
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2019-07-26)
The present work describes the manufacture of microstructures produced with femtosecond (fs) ultrashort pulse laser in transparent planar structures and optical fibers. The general objective of the research is the production ...
Surface morphology and structural modification induced by femtosecond pulses in hydrogenated amorphous silicon films
(Amer Scientific Publishers, 2015-03-01)
This work investigates the modification, resulting from fs-laser irradiation (150 fs, 775 nm and 1 kHz), on the structure and surface morphology of hydrogenated amorphous silicon (a-Si:H) thin films. The sample morphology ...
