The anticoagulant activity of surfaces decorated with cellulose nanocrystals (CNCs) prepared via sulfuric acid hydrolysis, is explored. Such surfaces bear a high amount of negatively charged sulfate groups, which mimic the naturally occurring anticoagulant heparin in terms of charge density. It is demonstrated that CNC decorated surfaces significantly enhance the coagulation times of blood plas...
A decoration of a hyperbolic surface finite type is choice circle, horocycle or hypercycle about each cone-point, cusp flare the surface, respectively. In this article we show that induces unique canonical tessellation and dual decomposition underlying surface. They are analogues weighted Delaunay Voronoi in Euclidean plane. We develop characterisation terms geometric equivalents Delaunay's emp...
We successfully prepared Au-nanoparticle-decorated ZnS (ZnS-Au) spheres by sputtering Au ultrathin films on surfaces of hydrothermally synthesized ZnS spheres and subsequently postannealed the samples in a high-vacuum atmosphere. The Au nanoparticles were distributed on ZnS surfaces without substantial aggregation. The Au nanoparticle diameter range was 5 to 10 nm. Structural information showed...
We construct geometric models for cluster algebras associated with bordered surfaces with marked points, for any choice of coefficients of geometric type, using generalized decorated Teichmüller spaces. In this context, the cluster variables are interpreted as suitably renormalized lambda lengths.
A regenerable electrochemical immunosensor with novel 3D DNA nanostructure-decorated gold surfaces was developed by taking advantage of DNA-directed antibody conjugation and high resistance to non-specific protein adsorption.
