In recent years, cold atmospheric plasma (CAP) is used for surface disinfection. However, little is known about its ability to improve biocompatibility of metallic surfaces when compared to thermal plasma methods. In this context, the study aimed to evaluate the response of human endothelial cells (Ea.

Results: X-ray diffraction (XRD) confirmed the incorporation of nitrogen into the treated steel. The surface treatment significantly increased SS roughness and hydrophilic characteristics.
A titanium surface nitrided by plasma contains nitrogen ions that guarantee resistance to corrosion and biocompatibility. Despite this, no descriptions concerning the influence of the expression of cell adhesion proteins and their influence on osteogenic cell differentiation are available. Thus, the present study aimed to assess the response of murine pre-osteoblastic cells (MC3T3-E1) cultured on nitrided titanium surfaces.

Electrospinning is widely studied as a method capable of producing nanofibers which enables cell attachment and proliferation, generating a functional scaffold that is suitable for many types of organs or tissues. In this study, electrospinning was used to obtain core-shell and monolithic fibers from the biocompatible poly (lactic acid) and poly (vinyl alcohol) polymers.
