Ms. Lefki Chaniotaki is a master student at the department of Materials Science and Technology at the University of Crete. She has received her bachelor in Materials science and Technology in 2019. She joined the Ultrafast Laser Micro- and Nano- Processing Laboratory of IESL in 2017, where she obtained her internship with Evi Kavatzikidou. She made positive PLGA replicas of silicon microstructures via soft lithography and then characterize them with UV-VIS, SEM and RAMAN. Moreover, in 2018-2019 she did her bachelor’s thesis in the same group, but she combined the prosthetic technique (FFF 3D printer) and ablative technique (laser ablation) to make 3D scaffolds with 3D ablation. Finally, in 2020 she started her master thesis where she continues the same topic as her bachelor’s thesis.
