Abstract Having plasmonic absorption within the biological transparency window, titanium nitride (TiN) nanoparticles (NPs) can potentially outperform gold counterparts in phototheranostic applications, but characteristics of available TiN NPs are still far from required parameters. Recently emerged laser-ablative synthesis opens up opportunities to match these parameters as it makes possible pr...

In the last decade, nanobiotechnology has evolved rapidly with an extensive impact on biomedical area. In order to improve bioavailability and minimize adverse effects, drug delivery systems based on magnetic nanocomposites are under development mainly for cancer imaging and antitumor therapy. In this regard, pH sensitive core-shell magnetic nanoparticles (NPs) with accurate controlled size and...

The concentrations of hydroxyl groups located inside and on the surface oxide films of a commercially pure titanium, cp-Ti, a type 316L austenitic stainless steel, SS, and a cobalt-chromium-molybdenum alloy, Co-Cr-Mo, were evaluated using X-ray photoelectron spectroscopy, XPS, and a zinc-complex substitution technique. As a result, the concentrations of the hydroxyl groups detected by the zinc-...

A new biomimetic strategy for modification of biomaterial surfaces with poly(ethylene glycol) (PEG) was developed. The strategy exploits the adhesive characteristics of 3,4-dihydroxyphenylalanine (DOPA), an important component of mussel adhesive proteins, to anchor PEG onto surfaces, rendering the surfaces resistant to cell attachment. Linear monomethoxy-terminated PEGs were conjugated either t...

Glenoid component loosening is a commonly encountered complication of total shoulder replacements. Therefore, focus has been placed on glenoid fixation. Porous metal implants, which promote biological fixation through osteointegration, have provided an uncemented alternative to the traditional cemented implant. In this explantation study, the authors examined the bone ingrowth and ongrowth of a...

Abstract The use of zinc oxide (ZnO) and titanium (TiO 2 ) nanoparticles in ultraviolet (UV) filters can cause serious health issues due to their genotoxicity cytotoxicity effect. Recent research on cerium (CeO has demonstrated biocompatible nature, excellent antioxidant ultraviolet–visible (UV–Vis) absorption properties. CeO -based nanocomposite materials or nano-architectures offer uniform ab...

Abstract In this study, analysis was performed of the macro characterization solar cells with chlorophyll dye from Syzygium paniculatum, using scanning electron microscopy (SEM) and energy-dispersive X-ray (EDX) analysis. Solar based on titanium dioxide (TiO2) nanomaterial S. paniculatum can increase efficiency due to flavonoids batulinic acid content. Photoanode TiO2 is one essential factors d...

Nanotechnology holds great promise for a plethora of potential applications. The interaction of engineered nanomaterials with living cells, tissues, and organisms is, however, only partly understood. Microscopic investigations of nano-bio interactions are mostly performed with a few model nanoparticles (NPs) which are easy to visualize, such as fluorescent quantum dots. Here the possibility to ...

Enhanced performance of polymer solar cells (PSCs) based on the blend of poly[N-9''-hepta-decanyl-2,7-carbazole-alt-5,5-(4',7'-di-2-thienyl-2',1',3'-benzothiadiazole)] (PCDTBT):[6,6]-phenyl-C70-butyric acid methyl ester (PC71BM) is demonstrated by titanium dioxide (TiO2) interface modification via CuInS2/ZnS quantum dots (CZdots). Devices with a TiO2/CZdots composite buffer layer exhibit both a...
