Abstract Selectively dendronized cellulose at C‐6 was synthesized homogeneously (in DMSO) and heterogeneously methanol) by the conversion of 6‐azido‐6‐deoxy (degree substitution, DS 0.75) with polyamidoamine (PAMAM) dendrons possessing an ethynyl focal moiety via copper‐catalyzed Huisgen reaction (click reaction) under mild conditions. First to third generation PAMAM‐triazolo derivatives values up 0.69 could be prepared, which are soluble in organic solvents (DMSO, DMF) water. The novel...

Biofunctionalized surfaces based on dendronized cellulose were prepared either by embedding 6-deoxy-6-(1,2,3-triazolo)-4-polyamidoamine (PAMAM) (degree of substitution, DS 0.25), obtained homogeneous conversion 6-deoxy-6-azido with propargyl-PAMAM dendron via the copper-catalyzed Huisgen reaction, in a acetate (DS 2.50) matrix or heterogeneous functionalization deoxy-azido film dendron. The amount amino groups provided solid supports was determined and covalent attachment enzyme proven...

Big data has evolved to a ubiquitous part of today's society. However, despite its popularity, the development and testing corresponding applications are still very challenging tasks that being actively researched in pursuit ways for improvement. One newly introduced proposition is application test driven (TDD) big domain. To facilitate this concept, existing literature reviews on TDD have been analyzed extract insights from those sources aggregated knowledge, which can be applied new...
