2. 1. Development of Nanocellulose Materials for Nano-filtration and Microfluidic Cell Culture

   Author : Lulu Wu; Maria Tenje; Natalia Ferraz; Pasi Kallio; Margareta Krabbe; Lars Evenäs; Caroline Adiels; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose nanofibrils; plasma-derived biologics; virus removal filtration; microfluidics; cell alignment; topography; shear stress.;

   Abstract : Nanocellulose, cellulose nanofibrils or nanocrystals, is an interesting material for a wide range of applications. It can be obtained from abundant sources (higher plants, bacteria and algae), and presents many advantages to be used in the biomedical field such as biological safety, high surface area, porosity, and tailorable rheological properties.

4. 2. Nano and Micro Patterned Organic Devices : From Neural Interfaces to Optoelectronic Devices

   Author : Tobias Nyberg; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : This thesis describes fabrication methods for optoelectronic devices (light emitting diodes (LEDs) and photodiodes) and structures for neural interfacing (neural electrodes and nerve guidance structures) using semiconducting and conducting organic materials as the active elements. Special importance has been attached to the patterning and processing of these devices. READ MORE

   Abstract : The focus of this thesis is placed on the fabrication of engineered nanodevices for the manipulation of soft matter thin films. By combining top-down micro- and nanofabrication approaches with bottom-up self-assembly strategies, new research platforms were developed, tested and characterized. READ MORE

7. 5. Functionalized Biomaterial Surfaces by Micro- and Nanofabrication

   Author : Sarunas Petronis; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanofabrication; surface characterization; surface topography; surface chemical composition; marine biofouling; force-sensing substrates; microfabrication; surface-enhanced Raman spectroscopy; cell-surface interaction; biointerfaces; biomaterials;

   Abstract : In the field of biomaterials, well-defined nano- and micropatterns or features at material surfaces can serve both as models for investigating material-biosystem interactions and as functional features for inducing, hindering or measuring specific bioreactions or biologic responses. Important bioreactions include protein adsorption and conformation, cell attachment and function, and adhesion and function of organized tissues or whole organisms. READ MORE
