Plants, algae and cyanobacteria have the amazing capacity to perform delicate photophysical and photochemical processes of light capture, excitation transfer, charge separation and catalysis in fluctuating living environments. As a consequence, photosynthetic proteins and membranes form dynamic architectures.…

This thesis is concerned with the constitution of chiral responsive matrix assemblies that may undergo light-driven conformational changes and self-select vibrations to develop vibronic states for driving semi-classical coherent transfer with nearly 100% yield in a lossless NCAP process.

Photosynthesis is the origin of life on earth, but it is a phenomenon that is still barely understood. Take, for example, the extremely efficient mechanism of electron transport. Leiden researchers demonstrate for the first time where one particular cause of this might be found.

Biophysicist Anjali Pandit has been awarded a FOM 'Projectruimte' research grant for her proposal ‘Tuning into the photosynthetic membrane with atomistic precision’.

In a promotional video for the SUNRISE initiative, prof. Huub de Groot explains the impact and ideas behind artificial photosynthesis.

In the programme NWO Open Competition Domain Science - GROOT, twenty new consortia will start a large research project. This boost of more than 47 million euros will make new research possible in the science domain. Among the winners is the Nanoscale Regulators of Photosynthesis consortium in which…

Plants use sunlight to perform photosynthesis, but with too much light they have to dim their activity and protect their cells against photo damage. The protein PsbS acts as a light-stress sensor and plays a key role in this process. Article in Nature’s Scientific Reports.

On Friday 10 July the Towards Biosolar Cells research programme was granted a budget of 25 million euros by the Dutch Government. The Ministry of Agriculture, Nature and Food Quality recommended the programme because it will contribute to green energy, improve food supplies and a create a more sustainable…

Plants could be regarded as small chemical factories, which produce chemical substances via photosynthesis. If we can imitate photosynthesis in an artificial system, we can make clean fuels and materials out of sunlight and CO2. Huub de Groot is very close to designing a system of this kind.

Huub de Groot is professor in Biophysical Organic Chemistry. With his team he works in the field of photosynthesis and artificial photosynthesis. The molecular basis for photosynthesis is formed by protein complexes and organelles that contain chlorophyll molecules. The antenna systems herein capture…

The Honours Class From Solar to Fuel with Bio consisted almost entirely of the workshop on Solar Biofuels from Micro-organisms that drew more than eighty specialist researchers to Leiden's Lorentz Centre in late March/early April. Students Erica Wenker (chemistry) and Jasper van Dobben de Bruijn (law)…

Using photosynthesis to generate energy, or using enzymes to effectively produce biofuel; Leiden chemists Huub de Groot en Hermen Overkleeft have both obtained an NWO TOP funding for their pioneering research. With the money they can take on new PhD students.

Research at the BPOC/SSNMR group is comprised of the following research themes:

How does the photoregulation mechanism work in detail?

The long term goal of the Biophysical Organic Chemistry/SSNMR group, headed by Prof. Huub de Groot, is to reach an understanding of structure, dynamics and functional mechanisms of membrane proteins and self-organized biological assemblies and to translate this knowledge into new concepts for nano-devices,…

Solar energy harnessed by plants and algae has great potential to be converted into biofuels for future generations.

Mycoheterotrophy is a particular mode of life in which plants obtain carbohydrates from their associated fungal partners, instead of by using photosynthesis.

Two things are needed to produce fuel from sunlight: an antenna that harvests light, and a light-driven catalyst. The most efficient antennae contain bacteria. An international team headed by Huub de Groot imitated them and discovered how they function.

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

The transition to new and renewable energy sources should be completed by 2050. Researchers in various disciplines at Leiden University are conducting unique research that will help us make this transition and reduce CO2 emissions.
