The use of titanium suboxides, known as Magnéli phase TiO$_x$, is expected to increase in the near future due to their desirable properties. In order to use Magnéli phase TiO$_x$ nanoparticles safely, it is necessary to know how nanoparticles interact with biological systems. In this study, the cyto ...

V doktorskem delu nas je zanimal biološki vpliv izbranih nanomaterialov, ki se lahko uporabljajo za medicinske namene. Vpliv nanomaterialov smo testirali s pasjimi ledvičnimi celicami MDCK in s človeškimi pljučnimi celicami A549 z lastnostmi alveolarnih celic tipa II. Glavni namen doktorskega dela j ...

Poorly soluble, low (cyto)toxic particles (PSLTs) are often regarded as one group, but it is important that these particles can be further differentiated based on their bioactivity. Currently, there are no biological endpoint based groupings for inhaled nanoparticles (NPs) that would allow us to sub ...

Over the last decades, the production of nanoparticles (NPs) has been rapidly growing on the global scale. The data on biological activity of NPs is crucial in evaluating their safe use and in the development of new products containing NPs. Different tests are available for the purposes of determini ...

The irradiation of metallic surfaces by high-fluence laser pulses in an oxygen-containing atmosphere inevitably modifies the surface topography, chemistry, and wettability. These modifications significantly influence cell-surface interactions and, consequently, surface biocompatibility. We investiga ...

The hematopoietic stem cell (HSC) niche undergoes detrimental changes with age. The molecular differences between young and old niches are well studied and understood; however, young and old niches have not yet been extensively characterized in terms of morphology. In the present work, a 2D stromal ...

Dialdehyde cellulose nanofibrils (CNF) and nanocrystals (CNC) were prepared via periodate oxidation (CNF/CNC-ox) and subsequently functionalized with hexamethylenediamine (HMDA) via a Schiff-base reaction, resulting in partially crosslinked micro-sized (0.5–10 μm) particles (CNF/CNC-ox-HMDA) with an ...

Use of orthopedic implants (OI) and dental implants (DI) is increasing due to obesity and ageing of the population. To increase the bio-functionality of metallic biomaterials, used for OI and DI, it is important to modify their surface composition, roughness, and structure without altering their mec ...
