1. Multidimensional Fluorescence Polarization Imaging of Single Light Harvesting Complexes
Abstract : This thesis presents my research journey in the Department of Chemical Physics,Lund University. Multidimensional fluorescence polarization imaging is used to study single LH2s. The method uses linearly polarized excitation light and the emission is detected through a polarizer. READ MORE

2. Dissecting the photosystem II light-harvesting antenna
Abstract : In photosynthesis, sunlight is converted into chemical energy that is stored mainly as carbohydrates and supplies basically all life on Earth with energy.In order to efficiently absorb the light energy, plants have developed the outer light harvesting antenna, which is composed of ten different protein subunits (LHC) that bind chlorophyll a and b as well as different carotenoids.

3. The light-harvesting antenna of higher plant photosystem I
Abstract : During photosynthesis, two multi-protein complexes, photosystems (PS) I and II work in tandem to convert the light-energy absorbed by the light-harvesting antennae into chemical energy, which is subsequently used to assimilate atmospheric carbon dioxide into organic carbon compounds. This is the main nutritional basis for life on Earth. READ MORE

4. Polarization portraits of lightharvesting antennas: from single molecule spectroscopy to imaging
Abstract : Multichromophoric systems are very important in photosynthesis and any device that uses solar energy for its operation. This is because multichromophoric light-harvesting antennas are responsible for the absorption of light and the efficient transfer of the absorbed energy toward distinct places where it is to be used or stored.

5. The roles of Lhcb1 och Lhcb2 in regulation of photosynthetic light harvesting
Abstract : Photosynthesis in higher plants relies upon collection of light by chlorophyll molecules associated with light harvesting chlorophyll a/b-binding (LHC) proteins. The two most abundant of these are Lhcb1 and Lhcb2, which make up light harvesting complex (LHC) II trimers. READ MORE
