Dr. Bergkvist's research interests involve several areas within nanobioscience and nanoengineering. Bionanofabrication/Biomimetics
Nature has over millions of years developed nanostructured systems and functional materials with unique properties, many capable of organized self-assembly in a bottom-up fashion. From a nanoengineering stand point it is advantageous to either utilize these biological systems as is, use components from them or to mimic their function to create new nanostructured materials with advanced function. Dr Bergkvist's research is aimed at creating engineered nanostructures and multi-functional materials by taking advantage of naturally occurring biological nanostructures, such a two dimensional self-assembled protein crystals, viral components and peptides. This "bionanofabrication" approach open alternative routes to create advanced materials with potential use in several diverse fields such as life-science (sensing, targeting and treatment applications), and energy (catalysts, harvesting and storage) etc. His expertise in surface science, colloidal chemistry, nanoparticle synthesis and biochemistry allows him to develop novel bionanofabrication techniques using a range of materials and biological templates. Nanobiotechnology at interfaces
Most biotechnological applications involve various non-biological interfaces, whether they are metallic, ceramic, polymeric or composite materials. Dr Bergkvist is on a fundamental, as well as a practical level interested how biological materials interact with these "non-biological" interfaces and how to manipulate and control that interaction. This area of research include biomolecular and organic molecular self-assembly, protein structure/function on surfaces, biophysics, cell-cell and cell-surface interactions. Materials of interest include for example, soft/hard polymeric materials for tissue engineering and emerging materials for semiconductor and VLSI fabrication which can be incorporated in electronic biosensor/diagnostic applications.
As an natural extension to effectively control biological interfacing to material, Dr. Bergkvist's is also engaged in research regarding surface characterization and surface chemical modification of interfaces (Self-assembled monolayer chemistry, etc.). Current focus in this area is on the modification of polymeric materials and high-K dielectrics.
Current nanobioscience research takes advantage of advanced nanofabrication technology integrated with biology for several purposes. We are interested in the fabrication of nanodevices as a mean to study biological processes (neuron signaling, single cell behavior, biophysics and biological assembly etc.), but also as for developing integrated bio-nano devices where biology and nanotechnology working in unison (applications involving MEMS, diagnostics, tissue engineering etc). CNSE offers unique, world class VLSI fabrication facilities where biological nanotechnology applications can be developed and scaled up to production levels needed to take developments in the laboratory to the masses. Above mentioned research come into play where control/tuning of surface chemistry and interfacial properties, combined with nanofabrication techniques enable layer-by-layer assembly, allow bottom-up self-assembled multilayer chemistries and provide guided patterning of biological molecules for fundamental research or practical integration in functional nanodevices. Nanoparticle/Nanowire synthesis
A key component in many nanosystems today involve organic/inorganic nanoparticles and nanowires. Dr. Bergkvists's lab is involved with the synthesis and derivatization of metal, magnetic, semiconductor and organic nanoparticles/vesciels for multiple applications in material and life-science.
