   Sammanfattning : Antimicrobial resistance (AMR) is one of the major global threats to thehealth of humans, animals, plants and ecosystems. AMR arises whenbacteria, viruses, fungi, and parasites undergo changes over time; makingmedicines such as antibiotics, antivirals, antifungals and antiparasiticineffective at treating infections.

3. 22. Synthesis and characterization of dendritic macromolecules based on 2,2-bis(hydroxymethyl)propionic acid

   Författare :Henrik Ihre; KTH; []
   Nyckelord :;

   Sammanfattning : Dendrimers are a relatively new type of macromolecules characterized by a well-defined, highly branthed, layered structure with a multitude of chain ends, adopting a globular shape at higher molar masses. Dendrimers are usually constructed from ABx type of monomers in either one of the two step-wise approaches known as thedivergentor theconvergent growth approach. LÄS MER

4. 23. Functional Dendritic Materials using Click Chemistry : Synthesis, Characterizations and Applications

   Författare :Per Antoni; Anders Hult; Michael Malkoch; Stefan Hecht; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dendrimer; Dendron; Dendritic; Hyperbranched; Click; Chemistry; CuAAc; One-Pot; Multi-functional; Simultaneous; Honeycomb; Isoporous; MALDI; NMR; GPC; TGA; DSC; Polymer chemistry; Polymerkemi;

   Sammanfattning : Förfrågan efter nya och mer avancerade applikationer är en pågående process vilket leder till en konstant utveckling av nya material. För att förstå relationen mellan en applikations egenskaper och dess sammansättning krävs full förståelse och kontroll över materialets uppbyggnad. LÄS MER

5. 24. Controlling DNA compaction and the interaction with model biomembranes

   Författare :Marie-Louise Ainalem; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; model biomembrane; DNA compaction; cryo-TEM; null ellipsometry; dynamic light scattering; toroid; bilayer; neutron reflectivity; dendrimer; PAMAM; DNA; poly amido amine ;

   Sammanfattning : The studies described in this thesis forms part of a larger collaborative project, Neonuclei, with the objective to design a module for packaging the negatively charged DNA into a ”neonucleus” with transcription competence. There are many applications that require control of DNA compaction, i.e. packaging or condensation. LÄS MER

7. 25. Multifunctional Dendritic Scaffolds: Synthesis, Characterization and Potential applications

   Författare :Yvonne Hed; Michael Malkoch; Mats Andersson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dendrimer; AB2C monomer; Click chemistry; CuAAC; thiol-ene coupling chemistry; TEC; linear dendritic hybrids; micelle; hydrogel; bone adhesive;

   Sammanfattning : The development of materials for advanced applications requires innovative macromolecules with well-defined structures and the inherent ability to be tailored in a straightforward manner. Dendrimers, being a subgroup of the dendritic polymer family, possess properties which fulfill such demands. LÄS MER
