  6. 9. Theoretical studies on photophysics and photochemistry of DNA

    Author : Yuejie Ai; Yi Luo; Lluís Blancafort; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; Kvantkemi; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Abstract : Theoretical studies on biological systems like nucleic acid and protein have been widely developed in the past 50 years and will continue to be a topic of interest in forefronts of natural science. In addition to experimental science, computational modeling can give useful information and help us to understand biochemical issues at molecular, atomic and even electronic levels. READ MORE

  7. 10. Novel fluorescent tools and techniques for 3D imaging of the cleared brain

    Author : Alex Yu Hin Wong; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: To better understand the complexity of the brain and how it becomes impaired under different pathological states, a considerably large number of brains would be needed for imaging to generate highly detailed maps in 3D. Chemical probes can offer a readily scalable labelling method that is robust, easy to use with the quick operation, and feasible for human tissue where genetic viral and toxin tracers are inappropriate.
