Influence of Initial Surface Roughness on LIPSS Formation and Its Consecutive Impact on Cell/Bacteria Attachment for TiAl6V4 Surfaces

open access: yesAdvanced Materials Technologies, Volume 8, Issue 12, June 23, 2023., 2023
Laser‐induced periodic surface structures (LIPSS) have been widely used as a direct micro and nano structuring technique, however, the influence of the initial surface roughness has not been extensively explored. In this paper we generate differently polished samples and see how LIPSS are formed, to further test the biocompatibility of the final ...

Thermo‐Responsive Microemulsions Containing Deep Eutectic‐Based Antibiotic Formulations for Improved Treatment of Resistant Bacterial Ocular Infections

open access: yesAdvanced Therapeutics, Volume 6, Issue 5, May 2023., 2023
Deep eutectic solvent‐based microemulsions with thermo‐responsive character have been developed and characterized as alternative chloramphenicol formulations to tackle ocular multiresistant infections. These microemulsions are shown to be more stable and effective, providing a sustained‐release and higher permeation of the drug into the ocular media ...

Amination of Polymeric Braid Structures to Improve Tendon Healing: An Experimental Comparison

open access: yesMacromolecular Materials and Engineering, Volume 308, Issue 1, January 2023., 2023
Poly(ethylene terephthalate) (PET) and poly(lactic acid) (PLA) are polymers useful in tendon repair, though with minimal success. There is a need to improve such scaffolds' design and physical–chemical nature. The work concerns functionalization of PET/PLA braids to incorporate amine groups in the braids' surface, improve cell adhesion, and ...
