Cell and Tissue Response to Modified by Laser-induced Periodic Surface Structures Biocompatible Materials for Dental Implants

2016

The use of femtosecond laser-induced periodic surface structures (LIPSS) for dental implants surface modification for improving cell adhesion and proliferation is reported. Results demonstrated higher response of cells on modified surface compared to untreated ones.

Cell and tissue response to nanotextured Ti6Al4V and Zr implants using high-speed femtosecond laser-induced periodic surface structures

2019

In this paper, the effect of femtosecond laser nanotexturing of surfaces of Ti6Al4V and Zr implants on their biological compatibility is presented and discussed. Highly regular and homogeneous nanostructures with sub-micrometer period were imprinted on implant surfaces. Surfaces were morphologically and chemically investigated by SEM and XPS. HDFa cell lines were used for toxicity and cell viability tests, and subcutaneous implantation was applied to characterize tissue response. HDFa proliferation and in vivo experiments evidenced the strong influence of the surface topography compared to the effect of the surface elemental composition (metal or alloy). The effect of protein adsorption fro…

Time resolved luminescence spectroscopy of CsPbBr3 single crystal

2020

Abstract The work reports the results of spectroscopic and luminescence-kinetic studies of CsPbBr3 single crystal over 14–300 K temperature range. It is shown that at low temperatures the luminescence spectrum contains three narrow bands at 534, 537, and 541.5 nm exhibiting a fast decay and a broad emission band at ca. 560 nm with long decay. The evolution of the luminescence bands and their temporal characteristics with temperature are discussed from the viewpoint of possible emission mechanisms. The origin of the luminescence bands is discussed in relation with the observed features of their temporal characteristics. The mechanism of luminescence quenching for different emission band is s…
