5. 3. Nanowires and Neural interfaces. Biocompatibility in the brain

   Author : Lina Gällentoft; NanoLund: Centre for Nanoscience; []
   Keywords : neural interface; neurons; BMI; nanowires; tissue responses; rat; biocompatibility; astrocytes; microglia;

   Abstract : Chronic neural interfaces that are able to record or stimulate neurons in the CNS are valuable instruments in use today and they hold great promise for the future both within neuroscience research and in the clinic. However, a major obstacle is that they show a decline in performance over time. READ MORE

6. 4. Nanoparticle-based drug delivery systems for neural interfaces - a novel approach for improved biocompatibility

   Author : Alexander Dontsios Holmkvist; Neurofysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Neural interfaces; brain damage injury; Minocycline; Gelatin; Nanoparticles; Drug-delivery systems; Biocompatibility; Tissue responses; immunohistochemistry IHC ; Poly D; L-lactic-co-glycolic acid PLGA ; Hydrophobic ion paring; Emulsification-solvent-diffusion method; Drug release; Microglia activation;

   Abstract : The overall purpose of this thesis was to reduce brain tissue responses around implanted microelectrodes using a pharmacological strategy. One of the main aims was to develop and evaluate drug delivery systems that allow local administration of anti-inflammatory pharmaceutics. READ MORE

7. 5. Mesoporous magnesium carbonate : Synthesis, characterization and biocompatibility

   Author : Sara Frykstrand Ångström; Maria Strømme; Johan Gómez de la Torre; Natalia Ferraz; Mika Lindén; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mesoporous; magnesium carbonate; pore size control; cytotoxicity; in vivo; skin irritation; acute systemic toxicity; hemocompatibility; Ca2 uptake; solubility enhancement; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

   Abstract : Mesoporous materials constitute a promising class of nanomaterials for a number of applications due to their tunable pore structure. The synthesis of most mesoporous materials involves a surfactant liquid crystal structure to form the pores. READ MORE
