Organic dots is a term used to represent materials including graphene quantum dots and carbon quantum dots because they rely on the presence of other atoms (O, H, and N) for their photoluminescence or fluorescence properties. Cargo delivery, bio-imaging, photodynamic therapy and photothermal therapy are major biomedical applications of organic dots.

Optimal Surface

AbstractSurface topography guides cell behavior and is a tool to endow biomaterials with bioactive properties. The large number of possible designs makes it challenging to find the optimal surface structure to induce a specific cell response. The TopoChip platform is currently the largest collection of topographies with 2176 in silico designed micro-topographies. Still, it is exploring only a small part of the design space due to the boundary conditions of the design algorithm and the surface engineering strategy. Inspired by the diversity of natural surfaces, we assessed to what extend we could expand the topographical design space and consequently the resulting cellular responses using natural surfaces. To this end, we replicated twenty-six plant and insect surfaces in polystyrene and quantified their surface properties using white light interferometry, image analysis and principle component analysis. Next, we quantified mesenchymal stem cell morphology and the pattern of Pseudomonas aeruginosa colonization and compared it to previous data from TopoChip screens. Our data show that natural surfaces extended the TopoChip design space. Moreover, the natural surfaces induced MSC morphologies and bacterial attachment patterns not previously observed on the TopoChip. In the future, we will train our design algorithms with the results obtained by natural surface imprint experiments to further explore the design space and bio-active properties of surface topography.

La1-xSrxMO3 nanoparticles have attracted increasing interest to material sciences due to their tunable Curie temperature (Tc), superparamagnetic nature and electrical properties, which could be utilized in magnetic hyperthermia treatment. However, La1-xSrxMO3 nanoparticles are toxity to biomolecules and very sensitive to oxidation because of their higher chemical reactivity. The surface modification could enhance stability, dispersibility and compatibility of La1-xSrxMO3 nanoparticles. This review article will introduce the progress on the synthesis and surface modification of La1-xSrxMO3 nanoparticles in recent years, and then give the perspectives of outlook.

Metallic biomaterial are the most suitable for replacing failed hard tissue up to now and for that is important to know the tribocorrosion resistance of these materials before use in biomedical applications. Surface engineering can play a significant role in extending the performance of medical implants made of titanium and its alloys. In this work was chosen electrodeposition of hydroxyapatite (HA) coatings into nanoporous titania layer formed by anodic oxidation as modified Ti-6Al-4V alloy surface. The comparative tribocorrosion behavior of untreated Ti-6Al-4V alloy surface, anodic nanoporous TiO2 surface and electrodeposited hydroxyapatite (HA) coatings into nanoporous TiO2 layers has been investigated in a bio-simulated fluid solution. The results of these investigations have shown that both surface treatments applied have improved the tribocorrosion resistance and friction coefficients as compared to the untreated Ti–6Al–4V alloy surface.
